Those "Dealerships" you worked at didn't care about maintaining their customers' batteries with the longevity of the batteries NOT their concern. Tap water in the customer's batteries means more battery SALES later on. THEY get to go "ha ha" at the fools who believe their bulls**t while they sell 'em a new battery that would have lasted MUCH longer with the use of Distilled Water.
@Davemike27 Because the "subject matter" turned out to be Distlled Water being used in both Radiators AND Batteries. In both instances, only DISTILLED WATER should be used -- due to huge variations in water hardness across the entire U.S.A. . Pity the fools who refuse to believe science when they say Tap Water "is just as good".
@@Davemike27because idiots put tapwater in their batteries which ruins the expected life of the battery by introducing sulphides into the lead plates. And adding tapwater to coolant completely negates using corrosion inhibitors and biocides and will cause the pump to work harder and is not the fluid the car was supposed to use ultimately reducing cooling performance and system performance overall
I'm a 30 plus year professional mechanic and have been told for many years that you have to use distilled water in cooling systems and batteries. I have in fact used both in the radiators and never seen a problem with either. Unless you use straight coolant or straight water. Either of those are bad. Now in a battery I only use distilled or DI water. Here's my theory, a cooling system is mixed with coolant which is going to dilute the water and condition it. So there won't be a build up especially if you flush it at the manufacturers recommend schedules. And it will just leave (at the worst case scenario) a thin film of scale and, when you flush your system, if you throw in some C.L.R. and flush it with that it will clean the mineral scale. As far as the battery is concerned, I never use tap water cause its impurities will stick to the sides of the lead plates shortening the life of the battery or shorting one or more of the cells and you can't just flush a battery.
So actually the reason to use distilled water is because distilled water is none conductive. Electrolysis in the system can cause damage to the engine faster this especially plays a part when you have iron to aluminum parts. I was under same impression for years that tap water made no difference but after dealing with a antifreeze rep for way to long there is a massive improvement of the life of the antifreeze which also means less radiator and heater core issues.
And that's totally fine. But for the price of one of those premixes, you can make 2 gallons of 50/50. Which is more beneficial if your car has a high capacity cooling system.
It makes your anti-freeze cost twice as much. The premix is 50/50 and cost the same as concentrate. The 50/50 mix is good for topping off only. If you get the Prestone yellow, it will mix well with any type anti-freeze.
Good point, I guess I overlooked the extra costs of it some how. Lol Thanks for pointing that out, I will keep that in mind next time I need to replace the coolant.
If the car is old and you don't want to throw money into it - it's ok. If you want to sell the car and pour in three tubes of leak patching dust - then that's a bitch move and these people should burn in hell.
For all the naysayers here - • Distilled water has zero minerals or impurities that can corrode the radiator and engine parts. • Distilled water has a higher heat transfer rate than most of the anti-freezing coolants available in the market. • Distilled water prevents electrolysis in the car’s cooling system and prevents scale formation. Tap water contains minerals that will eventually form deposits inside your radiator, plumbing, and water pump. This is also referred to as the hard water scale. This is all types of tap water we are talking about here, no matter where you live.Tap water has mineral deposits in it by nature. When tap water is repeatedly used in your cooling system, you will start to get a buildup of calcium and magnesium. This build-up is also referred to as a hard water scale, and you’ve likely seen it on your household appliances. When your radiator gets mineral buildup or hard water scale, it becomes less effective at cooling off those hot engine parts. And even just a little build-up is a huge problem. A 1/16-inch hard water scale will make your cooling system 40% less effective. That means your engine can get 40% hotter than it should, which can cascade into many other engine-related issues. A less effective cooling system can lead to your engine overheating. When your engine overheats, it can, and if untreated, will cause damage to your engine. Some engine parts will warp with the heat they are not meant to withstand. Common parts that break and require repairs after engine overheating include a cracked head gasket (average replacement cost $1500), warped cylinders (average replacement cost $500), and water pump replacement ($350- $700). It is much cheaper to be proactive and replace your coolant with the proper ingredients before negligence or laziness leaves you without the convenience of your vehicle because it is in the shop undergoing a costly repair.
Dude you explained this so perfectly. People seriously don't understand the ramifications of using tap water in their car. I believe that's why none of my cooling system components have gone out yet. My aunt used to always get it maintained at a local shop that does great work and does not skimp. I'm sure he's sold her coolent flushes and anytime it was topped off she never used water. I've only ever used coolant to top off and have always been good.
Everyone here should stop reading other comments once they've read this since the facts are here. Why use tap water on a multi thousand dollar vehicle? Distilled water is less than $2 a gallon.

Tap water works just fine I’m a mechanic dads a mechanic been using it since like 2010 when everything started to get absurdly expensive and all cars are working just fine
I’ve used tap water to mix coolant, and when I pulled the motor apart a couple years afterward, it had kidney stones in the water passages. Always use distilled water, especially if you have hard water
The reason why you don't want to use tap water is because of electrolysis. It will cause build up and corrosion in your cooling system over time. It also makes quick work of the plastics which have become so commonplace now on newer engines. Distilled water doesn't contain ions, therefore it doesn't conduct electricity. It literally costs under a dollar at the supermarket. Just buy a couple gallons and store it at home for future use. In case of an emergency, it can be drank. 👍🏽

keeping your coolant clean and changing it every few years will counter any issues the average person has with tap water over the average life span of the vehicle. Basically, you can go to ridiculous measures, but what do you really gain in the long run, unless you keep the car for like 30 years.
That is if, you have one of the lame GM vehicles that came with orange coolant. And then of course you’re looking forward to having coolant leaks and corrosion problems in the future no matter what, unless you get it all flushed out and replaced with a quality coolant mixture. 👌
I hate those jugs. You can't even tell where the 5th quart line is. I never use those jugs for mixing. I use a kitchen JAR with all the marked lines on the side for more accuracy
I buy the Mobil1 oil in the 5 quart jugs and those also don't have a 5th quart line so my workaround is..... 🤫 When I buy the jug new, I use a sharpie to mark where the oil level is. I hope it's accurate. 😆
They say to use distilled water because the minerals in regular water can mess up your thermostat and clog up your cooling system. Distilled water is also recommended for water cooled PC’s. Same principal on a smaller scale.
Just get a bucket and pure both the antifreeze concentrate and the one gallon of distilled water. Pure what you need in to your radiator and the rest in to antifreeze bottle.
So long as the concentrate contains > 95% ethylene glycol (which has a boiling point of 200° Centigrade) and the water is distilled/demineralised. A telling feature of the concentrate is density; must be greater than 1090g/litre..
Yes. Tap or hose water has ions and particles in it that will solidify in your coolant loop and are very difficult to remove and at some point, impossible. Distilled water has nothing in it, no ions to stick to hoses or anything. But it's really bad to drink 😅
Good video, would you make another video showing why it is important to use distilled water, and why coolant/anti freeze is mixed with distilled water. As a young man i had no clue about this info. In modern cars, they have many different metals in the system. * Also - how often should the coolant be changed. Doing the correct maint. can prolong the life of things in system like, water pump, thermostat, radiator. Not to mention avoiding over heating and a frozen engine block in freezing temps. There is alot to this subject for the DIY folks who are new to car maint. I like your videos, good job.
No sense making another video on this subject, because at least half of the respondants are arguing against the use of Distilled Water, claiming that "it doesn't matter" which kind of water is used in Batteries and Radiators. I use ONLY Distilled Water in our Batteries and Radiators. What other people do is none of my business.
50/50 mix is the bare minimum to mix it. Have not done that in 40 years, I always do a 70/30 mix antifreeze being the 70 percent, you have a higher boil temperature and lower freeze protecting.
I was standing at autozone Waiting to talk to the manager.. And I noticed on their signs they changed it to "just add distilled water" and "use only distilled water" posted everywhere now.. Most of the jugs said it too.. instead of "just add water" like yours
Fur reals! I used to use tap water for headlight fluid and it made the lens really chalky! Now that I've been using distilled water with a custom-made funnel, my headlight lenses are crystal clear! =D
I got rid of DEX-COOL…….was going through radiators and water pumps for quite a while. Went back to the old school yellow and never had the problem again.
They used to sell distilled water at O’Reilly for that purpose. FUN FACT. In the winter a 60/40 mix is more stable, and in summer a 40/60 mix is more stable. That’s why it’s 50/50. Also, no need to be so precise. Shoot from the hip, you’ll be fine.
WTF are you talking about !?? The "stability" of a chemical mixture DOES NOT vary with the 4 Seasons. It's 50/50 for convenience AND accuracy, plus the 50/50 mixture fits exactly within the normal temperature range of engines operated in the U.S.A.
@@SlikLizrd yes, and the thermal stability of a 60/40 mix in winter is better than a 50/50 mix. And a 40/60 mix is more stable I. The summer. That’s what the HELL I’m talking about. Do you have google, read some articles on coolant principles and applications.
@@MechanicalTriage Oh, I see -- in order to maintain that "stability" that you suggest, I just need to change out my coolant 2wice per year. Gotta keep that "stability", eh !?? NAH. It's 50/50, year 'round -- just like the Car Makers and the Coolant Makers recommend -- and the ratio that I have used succesfully since Ethylene Glycol was introduced as an automotive coolant, several decades ago.
This method will easily leave the engine under-dosed with concentrate. Read the manual. Add the correct % volume to the cooling system (eg 50%). Top up with distilled water. This ensures that anything trapped in the system cannot dilute your coolant below its correct concentration.
I worked at a dealer for 10 years. They never had distilled water in the parts department and we always filled batteries and radiators with tap water. Never had a comeback due to using tap water.
Over the decades I've only used tap water, never a problem. But the last couple of vehicles I bought a couple gallons of distilled water. It's cheap and for the couple of times it's done over the years...why not?
I think the last time that I did my radiator draining & fill. Instead of mixing containers, I drained the system, flushed it with a bit of hose water. Waited for it to drip out. Filled up the system with the concentrate and the water and let the system do the mixing for me!
Actual distilled water is not as easy to find as you might think. Check that it has nothing added. I always buy premix 50/50 and if you need 70% antifreeze add concentrate to the premix.
It is in every grocery store in my town, right next to the gallon jugs of drinking water. It is also usually found in drug stores. I have never had a problem finding distilled water.
It doesn't matter, I have been filling my truck with tap water/coolant for 25 years with zero issues. Does this mean you won't, not at all, but from my experiences, it doesn't matter.
This is moot if you have a filter. Added one to my truck about 5 years ago. Best part is, you can get replacement filters that have conditioners in it to revitalize your coolant so you dont need to flush it under normal circumstances.
I've used Water from a garden hose for over 100 demo derby cars with no issues. Lol. But, I've also used that water mixed with 100% coolant and never had issues in any vehicle over the past 30 years. Now, the oldest in my fleet now is from 2000. So it's only 23 years old. But it still runs fine, and has NEVER had a coolant issue. I'll ask you. Why don't you run well or city water in the system, if that water is clean enough to drink??? Here's why it's on there. Distilled water lacks impurities, but clean drinking water has such a small amount that it's "safe" to consume. You're coolant system will be fine if you use well or city water. However, there is a possibility your cooling system will corrode premature, however, with clean water, it's so slow, it'll never happen in our lifetimes. With older copper and brass radiators, it can happen in years, but all new systems are plastic and alum. So why is it on the bottle, to use distilled??? To save them from lawsuits when older cars fail, and it never left from the early 80s when those brass/copper rads were used. If you have a 1989 or never Chevy (not sure for others) you are fine using the drinkable tap.😊
All my mechanic friends and I always used distilled water after doing cooling system repairs in the early 80’s …😆😂🤣. Technically you should use distilled water,but I guarantee you if you had cooling system repairs done at any repair shop,the water is coming from a hose,not a bottle. All the owners manuals (far back as the 60’s & 70’s said “distilled water”. On a newer car you should drain and refill every other year when the car hits 40-50,000 just to keep the acidity low so you don’t blow gaskets as much. Antifreeze isn’t good for 100 grand just like oil change intervals shouldn’t be 10 grand either…if you plan on keeping it!!
@@SD-pi9co no water softener and minerals make no difference cause they dont create more of themselves from nothing and build up like people claim. It's just another excuse for stealerships to charge you more for basic service work that doesn't take long and doesn't require much to do. Go ahead and believe everything else you read on the internet. Lol
Never use faucet water in a radiator it will scale up over time and plug up its channels always have distilled water 💧 after you put in your concentrated anti-freeze.

as a mechanic i want everyone to know ur car at a dealership or shop is getting tap water mixed with concentrate. i’m just giving you the facts. never seen it cause a problem.
Using Dex-Cool is a mistake... according to some people. Seems fine in my 2003 GMC 4.3, but I do change it every 3 years (rather than the 5 GM recommends). Five seems fine for the green stuff in my 1999 Ford. My 1997 Toyota gets only the proper Toyota red specification stuff.
I used to only use 50 50 in my cars, I had a honda that would take on long distance trips and I would notice after a few months that my levels got lower, I started adding a bit of concentrate, about half a bottle, and I didn't have anymore overheating issues or it boiling out..
The problem with mixing 50/50 is, you still have coolant in the system, even after a flush, and you don't know if that was 50/50. The 50/50 you put could and will probably be more diluted from the liquid still in the engine,
This is just as saying the #1 mistake when put transmission in park is not using hand, parking or e brake, before after or not at all, it doesn't matter, it doesn't ruin the transmission... AT ALL!!!
It so much easier if you just use Shell Rotella 50/50 prediluted, it cost more, it pre mixed and it's good for 5 years! I have used it in hundreds of Diesel Engines for over 20 years it's the best I have ever used!!!
I've read not to use distilled water either. Says something about it stripping electrons from metal. Said soft water is what to use. I have no fkn clue so I just starting buying the pre mixed.🤯
I was rather surprised how many local mechanics use tap water. I've always used deionized water (typically good ole distilled water from the grocery store).
I remember my friend wanted me to flush his trucks radiator. The rust was so bad it looked like mud and I had to break it loose with a clothes hanger. I didn't bother doing a flush with cleaning chemicals it was so bad I opened the bottom shove a garden hose in the top ran the truck at the same time till it was only clear water the I took clean and distilled water and did a final washout with that then used 50/50 mix then he wrecked it a week later 😂
Tap water is full of heavy metal & mineral salts, which plate out in your engine’s cooling system, and eventually lead to corrosion problems. This is especially critical in aluminum engines, as some of the minerals/metals are horribly corrosive to aluminum. Distilled water is cheap.

Never had a problem...right away. It takes time for precipitates to form and start to cause issues.
GM's DEX COOL should ALWAYS
be purchased already 50/50 mixed..they use the proper distilled water so you don't have to..👍
That is if, you have one of the lame GM vehicles that came with orange coolant.
And then of course you’re looking forward to having coolant leaks and corrosion problems in the future no matter what, unless you get it all flushed out and replaced with a quality coolant mixture. 👌
I hate those jugs. You can't even tell where the 5th quart line is. I never use those jugs for mixing. I use a kitchen JAR with all the marked lines on the side for more accuracy
I buy the Mobil1 oil in the 5 quart jugs and those also don't have a 5th quart line so my workaround is..... 🤫 When I buy the jug new, I use a sharpie to mark where the oil level is. I hope it's accurate. 😆
I don't think a few ounces off is gonna make a big difference buddy lol
are you really worried about that 3 degrees difference when 50/50 is already good to about -25 degrees F?
There is no fifth quart mark because it's a gallon jug.

You can get free distilled water from your condensing tumble dryer. Use Distilled water also for screen wash dilution.
True!
They say to use distilled water because the minerals in regular water can mess up your thermostat and clog up your cooling system. Distilled water is also recommended for water cooled PC’s. Same principal on a smaller scale.
Just get a bucket and pure both the antifreeze concentrate and the one gallon of distilled water. Pure what you need in to your radiator and the rest in to antifreeze bottle.
That funnel is AWESOME!!!
Better yet you should explain why distilled water is recommended versus tapwater. Because I know I have never personally used distilled water.
Dex Cool. I have that on my 1998 Chevy Cavalier.
To all the boat owners. Make sure your lake is distilled water
dis a joke right?
Thanks. Made my day!
😊
Its usually distilled from the ocean
Lake water and distilled big difference in bacteria idiot
So long as the concentrate contains > 95% ethylene glycol (which has a boiling point of 200° Centigrade) and the water is distilled/demineralised. A telling feature of the concentrate is density; must be greater than 1090g/litre..
Yes. Tap or hose water has ions and particles in it that will solidify in your coolant loop and are very difficult to remove and at some point, impossible. Distilled water has nothing in it, no ions to stick to hoses or anything. But it's really bad to drink 😅
This dude never drank from the hose as a kid.
Too late, I filled your brand new chevy with dexcool and tap water when it had 7 miles on it at the dealership. :3
😂
Good video, would you make another video showing why it is important to use distilled water, and why coolant/anti freeze is mixed with distilled water. As a young man i had no clue about this info.
In modern cars, they have many different metals in the system. * Also - how often should the coolant be changed. Doing the correct maint. can prolong the life of things in system like, water pump, thermostat, radiator. Not to mention avoiding over heating and a frozen engine block in freezing temps. There is alot to this subject for the DIY folks who are new to car maint. I like your videos, good job.
No sense making another video on this subject, because at least half of the respondants are arguing against the use of Distilled Water, claiming that "it doesn't matter" which kind of
water is used in Batteries and Radiators.
I use ONLY Distilled Water in our Batteries and Radiators.
What other people do is none of my business.
Really depends how good your water is. I fortunately live where the water is really good. However some places you definitely cannot add hose water.
Seems extremely silly to not spend a buck or two for a bottle of distilled water.
how good is your "good water" anyways
I'm 60 years old I've never mix with water just straight antifreeze never had a problem an live in Michigan
If I have left over real anti-freeze, I mix it with distilled water for when the reservoir gets a bit low.
"Team Straight To The Hose" 🙋🏾♂️.
This is why I don't buy expensive antifreeze and have to mix it myself as I buy it already pre-mixed.
Make sure that it doesn't have minerals added for flavor because that is gold reasoning for using
50/50 mix is the bare minimum to mix it. Have not done that in 40 years, I always do a 70/30 mix antifreeze being the 70 percent, you have a higher boil temperature and lower freeze protecting.
Too strong unless you in major freeze zone
I've just always used clean well water in my batteries and auto cooling systems and never had an issue.
I was standing at autozone Waiting to talk to the manager.. And I noticed on their signs they changed it to "just add distilled water" and "use only distilled water" posted everywhere now..
Most of the jugs said it too.. instead of "just add water" like yours
Yes tap water has minerals that can build up
I mix headlight fluid this way too
Fur reals! I used to use tap water for headlight fluid and it made the lens really chalky! Now that I've been using distilled water with a custom-made funnel, my headlight lenses are crystal clear! =D
@@dawabbitt3079 tap water not good for anything
Home boy forgot to mention that the flouride in tap water will ruin your vehicles 3rd eye. 👁 🤦♂️
I got rid of DEX-COOL…….was going through radiators and water pumps for quite a while. Went back to the old school yellow and never had the problem again.
I've run Dex Cool in my 25 year old truck with 300,000 miles and never had an issue.
70/30 is the correct mix. More antifreeze than water. Less corrosion and problems.
They used to sell distilled water at O’Reilly for that purpose. FUN FACT. In the winter a 60/40 mix is more stable, and in summer a 40/60 mix is more stable. That’s why it’s 50/50. Also, no need to be so precise. Shoot from the hip, you’ll be fine.
WTF are you talking about !?? The "stability" of a chemical mixture DOES NOT vary with the 4 Seasons.
It's 50/50 for convenience AND accuracy, plus the 50/50 mixture fits exactly within the normal temperature range of engines operated in the U.S.A.
@@SlikLizrd yes, and the thermal stability of a 60/40 mix in winter is better than a 50/50 mix. And a 40/60 mix is more stable I. The summer. That’s what the HELL I’m talking about. Do you have google, read some articles on coolant principles and applications.
@@MechanicalTriage Oh, I see -- in order to maintain that "stability" that you suggest, I just need to change out my coolant 2wice per year.
Gotta keep that "stability", eh !??
NAH. It's 50/50, year 'round -- just like the Car Makers and the Coolant Makers recommend -- and the ratio that I have used succesfully since Ethylene Glycol was introduced as an automotive coolant, several decades ago.
I mean usually it’s not a big deal because the coolant has additives to prevent any corrosion or anything
This method will easily leave the engine under-dosed with concentrate. Read the manual. Add the correct % volume to the cooling system (eg 50%). Top up with distilled water. This ensures that anything trapped in the system cannot dilute your coolant below its correct concentration.
I also put a zip tie on the bottle so I know it’s a mixed bottle
I use a sharpie and write mixed on my bottle.
Sharpie
It's the mineral content of the water that causes blockage of the core
and use distilled water and the wiper washer mix so you don't have hard water spots on the paint
I worked at a dealer for 10 years. They never had distilled water in the parts department and we always filled batteries and radiators with tap water. Never had a comeback due to using tap water.
50/50 mix is a general guideline, mix your coolant according to the climate you will be driving in
Over the decades I've only used tap water, never a problem.
But the last couple of vehicles I bought a couple gallons of distilled water. It's cheap and for the couple of times it's done over the years...why not?
I think the last time that I did my radiator draining & fill. Instead of mixing containers, I drained the system, flushed it with a bit of hose water. Waited for it to drip out. Filled up the system with the concentrate and the water and let the system do the mixing for me!
Actual distilled water is not as easy to find as you might think. Check that it has nothing added. I always buy premix 50/50 and if you need 70% antifreeze add concentrate to the premix.
It is in every grocery store in my town, right next to the gallon jugs of drinking water. It is also usually found in drug stores. I have never had a problem finding distilled water.
@@eilliwwasniahc a lot of it has minerals added. Last time I checked there was nothing.
It's 5 aisles over from the Antifreeze at Walmart.
I don't actually need it.
It doesn't matter, I have been filling my truck with tap water/coolant for 25 years with zero issues.
Does this mean you won't, not at all, but from my experiences, it doesn't matter.
This is moot if you have a filter. Added one to my truck about 5 years ago. Best part is, you can get replacement filters that have conditioners in it to revitalize your coolant so you dont need to flush it under normal circumstances.
I've used Water from a garden hose for over 100 demo derby cars with no issues. Lol.
But, I've also used that water mixed with 100% coolant and never had issues in any vehicle over the past 30 years. Now, the oldest in my fleet now is from 2000. So it's only 23 years old. But it still runs fine, and has NEVER had a coolant issue.
I'll ask you. Why don't you run well or city water in the system, if that water is clean enough to drink??? Here's why it's on there. Distilled water lacks impurities, but clean drinking water has such a small amount that it's "safe" to consume. You're coolant system will be fine if you use well or city water. However, there is a possibility your cooling system will corrode premature, however, with clean water, it's so slow, it'll never happen in our lifetimes. With older copper and brass radiators, it can happen in years, but all new systems are plastic and alum.
So why is it on the bottle, to use distilled??? To save them from lawsuits when older cars fail, and it never left from the early 80s when those brass/copper rads were used. If you have a 1989 or never Chevy (not sure for others) you are fine using the drinkable tap.😊
All my mechanic friends and I always used distilled water after doing cooling system repairs in the early 80’s …😆😂🤣. Technically you should use distilled water,but I guarantee you if you had cooling system repairs done at any repair shop,the water is coming from a hose,not a bottle. All the owners manuals (far back as the 60’s & 70’s said “distilled water”. On a newer car you should drain and refill every other year when the car hits 40-50,000 just to keep the acidity low so you don’t blow gaskets as much. Antifreeze isn’t good for 100 grand just like oil change intervals shouldn’t be 10 grand either…if you plan on keeping it!!
Have done it with hose water my whole life and never had any problems. Lol
You like minerals floating around inside your engine? And the salt added by your water softener. Shade tree mechanic.
@@SD-pi9co no water softener and minerals make no difference cause they dont create more of themselves from nothing and build up like people claim. It's just another excuse for stealerships to charge you more for basic service work that doesn't take long and doesn't require much to do. Go ahead and believe everything else you read on the internet. Lol
My grandmothers Datsun that she purchased new in Texas has had nothing but water in it. Still running
Texas stays hot enough that it won't freeze I'm hoping lol
@@justjamesAMX well it's been in Mexico for most of its life
@@w900kw2 fair enough, yeah water is fine as long as you don't let it freeze
@J H we did have a problem with it freezing one time only. We ran it without serpentine belts for a couple minutes.
😀👍🏿Great Tips,Good Stuff
Never use faucet water in a radiator it will
scale up over time and plug up its channels
always have distilled water 💧 after you put
in your concentrated anti-freeze.
I've been using distilled water in my cooling systems & batteries for YEARS.
I thought everyone knew this??
NOPE!
You gotta remember, not everyone is like us! 😂🤣😂. Same concept with computers.... we have very computer illiterate people in 2023.
Everyone has their own specialty.... i might know how to drop a trans engine and tear down everything, but i wont know baking welding or fishing like the next person 👍
Distilled is a thing of the past.
@@IndiansAuto It's STILL for sale all over the U.S.A. !!
I thought everyone knew that Donald Trump is and always was a ticking time bomb -- but he's still around, spreading hate and discontent wherever he goes.
President Joe Biden's the guy who "reads the instructions". Joe Biden was the People's Choice.
2wice-impeached, disgraced, ex-President Trump is the guy who "knows better" than anybody about anything. Trump never won the Popular Vote. He was NOT the People's Choice.
Makes ya wonder.
Same here
But did you read the car manual for what the car requires?
Just look up the capacity of the cooling system and divide by 2. Then make a gallon of 50/50 mix and keep that on hand.
as a mechanic i want everyone to know ur car at a dealership or shop is getting tap water mixed with concentrate. i’m just giving you the facts. never seen it cause a problem.
I try to explain this to people at my parts job and they never understand...
It’ll mix itself in the car don’t over complicate it.
Crazy how red it looks on camera. Not orange at all.
Using Dex-Cool is a mistake... according to some people. Seems fine in my 2003 GMC 4.3, but I do change it every 3 years (rather than the 5 GM recommends). Five seems fine for the green stuff in my 1999 Ford. My 1997 Toyota gets only the proper Toyota red specification stuff.
I used to only use 50 50 in my cars, I had a honda that would take on long distance trips and I would notice after a few months that my levels got lower, I started adding a bit of concentrate, about half a bottle, and I didn't have anymore overheating issues or it boiling out..
The problem with mixing 50/50 is, you still have coolant in the system, even after a flush, and you don't know if that was 50/50.
The 50/50 you put could and will probably be more diluted from the liquid still in the engine,
The zerex brand says mix with clean tap water or distilled water.
Distilled water is a dollar a gallon at Walmart or you can make it like I do
This is just as saying the #1 mistake when put transmission in park is not using hand, parking or e brake, before after or not at all, it doesn't matter, it doesn't ruin the transmission... AT ALL!!!
if the water is potable then its fine to mix in your coolant. The container also says "Do Not Drink"...So... there`s that
no there are minerals in drinking water that can clog the fins and gunk up the works so distilled is best
I've used tap water for almost 50 years without issue. Maybe low mineral content in Rhode Island?
I maintain over 250 of the same engines some for over 30 years, I've never used distilled water. just saying. but I like that funnel
If you know the capacity, dump both in with a total gallon to spare.
It so much easier if you just use Shell Rotella 50/50 prediluted, it cost more, it pre mixed and it's good for 5 years! I have used it in hundreds of Diesel Engines for over 20 years it's the best I have ever used!!!
20 year tech here, you can use water from the tap. Never had an issue, ever
You wouldn’t see a problem u til down the road. You completely missed the point bubs. How many customer vehicles have you filled with the garden hose?
@@teamdada2194 literally hundreds, no comebacks bub
I've read not to use distilled water either. Says something about it stripping electrons from metal. Said soft water is what to use. I have no fkn clue so I just starting buying the pre mixed.🤯
That's some good looking Kool-Aid
I was rather surprised how many local mechanics use tap water. I've always used deionized water (typically good ole distilled water from the grocery store).
Just... Get a harbor freight bucket. Throw on gallon of concentrate , and one gallon of distilled water, mix it.. it's ready
Yeah most tracks require water. Only ran hose water in alot of dirt track cars. Never had a issue
I remember my friend wanted me to flush his trucks radiator. The rust was so bad it looked like mud and I had to break it loose with a clothes hanger. I didn't bother doing a flush with cleaning chemicals it was so bad I opened the bottom shove a garden hose in the top ran the truck at the same time till it was only clear water the I took clean and distilled water and did a final washout with that then used 50/50 mix then he wrecked it a week later 😂
Would reverse osmosis pure water be just as good as distilled water?
Pro tip. If you are in a pinch most fluids (no sugars) can be used as coolant. I mean if you really need to. Piss in that radiator.
Tap water is full of heavy metal & mineral salts, which plate out in your engine’s cooling system, and eventually lead to corrosion problems. This is especially critical in aluminum engines, as some of the minerals/metals are horribly corrosive to aluminum. Distilled water is cheap.
If tap water was full of heavy metal, we would have much more pressing issues to be dealing with.
