He's just saying use what the manufacturer tells you to and he's right also he's right about the air and removing the thermostat. I've been a professional mechanic for 23 years, I use distilled water but I've used tap water in the past and it's never caused any damage so I'm not sure how true that is that you have to use distilled water.
You can back flush the engine with good ole tap water and then fill it with distilled and the rad flush additives to nuetralize any minerals and run it for a while, just dont want the tap (or mainly city water)it in there long term. Drain and fill 50/50 with distilled. Its honestly more of an issue based on your water quality.
So if you put water in and it’s only to flush it you should be fine idk why people are such but hurt 🐈 about distilled water if it’s temporary then there’s no real issue I see
I personally don’t know a single professional automotive technician or automotive shop that uses distilled water. That’s just been my experience. Thank you.

@@chrisvelazquez5167 lol no I know I’m just joking. I personally do not know any professional, working automotive techs that use it in their personal vehicles for doing a coolant service. Good question though
Undo the lower coolant hose. Let it drain. Reattach hose. Add water. Run vehicle until thermostat opens. Rinse and repeat. Careful handling hot water/coolant. That will clean out the system. Then add concentrated coolant until it’s a 50/50 mix. Hope that makes sense
Yeah the hard water isn't optimal. But I've worked at Luxury dealers & independent shops. Everyone just uses tap water for flushing and diluting coolant. There's no big special tank in the shops for distilled water. I would imagine in a performance or race shop they might. It would be interesting to hear input from someone that works in that side of the industry.
@@aiyogarage Using distilled water for mix is the proper way as tapwater is very corrosive with mineral buildup a prime example is your water heater has anode (aka sacrificial rod, )that gets badly damaged just from the tapwater, so what do you thinks gonna happen to your engine block? It becomes the sacrificial block with tapwater, especially since a lot of those places don’t even use proper filtration and even if you did there still a mineral deposits. You can ask any car detailer why they don’t use tapwater either .

@@Asimo44 modern vehicles have specific coolant fluid requirements. Using green/generic coolant isn’t ideal, but if that’s all you have it’s better than nothing. It’s just frustrating as a tech and you go to work on the cooling system and you see green coolant. Now you have to also try and sell a coolant flush so you’re not mixing different coolants. Just trying to get the word out there 👍
@@Asimo44 I’m saying I don’t use distilled water at all. Any shop that has ever serviced your car does not use distilled water either. Common practice. Not saying it’s right, you should always follow manufacturer instructions. But just being honest with the public about it
@@aiyogarage so you say green coolant is bad but then you also say you don't follow manufacturer's instructions? Kinda just lost all your credibility there. I'll keep using green coolant and distilled water. 👍
I'm not aware of any shop or dealership that takes the time to mix coolant with distilled water. There really isn't time. Just straight tap water. I know I've seen it in work instructions before, and I'm sure loads of forums say only mix coolant with distilled water. But really the important thing is making sure you're using coolant that was designed for your specific vehicle. Hope that makes sense. If you're into performance or racing its a whole different subject. Hope that helps. Thanks for watching.
I stopped using green years ago and moved to Orange Dexcool in my trucks, for my car I use purple coolant. I like the pre-mixed because it’s just easier after I flush. However, never ever mix coolants.
lol yeah thats over 20 years old, green should do you just fine. Always go with what the manufacturer recommends. That statement is for people putting universal coolant in a modern vehicle.
I use Prestone Green in my '68 C/10 and '71 GMC Jimmy. The orange stuff would corrode my Brass radiator and heater cores. For my '03 Tahoe the Dexcool Orange works. They don't mix.
Instead of removing the hoses and the thermostat can you just open the petcock on the radiator and turn heater on and flush it that way? Im assuming removing the hoses and thermostat is just quicker?
@@vasilybk1760 It's not about being lazy, its about being efficient. If you'd ever worked in a flat rate environment you would understand what I was talking about.
@@aiyogarageIf it’s a warm day (75°) is it a bad idea to drain and fill with pure water, then drive the truck (~50 miles) to flush/dilute the contaminants in the system before refilling with new coolant?
It's important to use air to get as much of the water out of the system so you don't dilute your coolant too much. You can always use an Antifreeze Coolant Refractometer (on Amazon for like $20). to double check the freezing of the coolant point after you've completed the flush and re-fill.
great question! a lot of the materials used in manufacturing modern vehicles are not compatible with green. You could use green in an emergency, but I would always go with coolant specific to your vehicle. hope that helps
@@aiyogarage thank you for taking the time to let me know but whenever I buy universal fluid for my Altima, it always comes to be green if it's Preston

@@Imadethistocomment13 Hey no worries. I would consider that a somewhat older car and wouldn't be too worried about putting universal coolant.

Feel free to check out more videos on the channel and to ask more questions.
You could in theory, but I would strongly advise getting a new head gasket installed on your engine. And at that point, probably do some other tuneup related work.
I would sort out the head gasket situation first. That'll take priority over maintenance. There's also a small chance that coolant could flood the cylinder well and cause internal engine damage.
Idk where you got that information.. but it is entirely wrong. Putting water in the coolant system is a common practice. Example: On a race track, coolant is not aloud in the cooling system, only water. Please feel free to reach out if you have any more questions or concerns.
People were putting water as coolant for their car in the 50’s, we only stopped because the invention of antifreeze and when they saw that over LONG periods of time water could rust or be frozen in the engine. In an emergency you could pour in water to make it to the closest shop. So doing a flush with water then air to mostly clean it doesn’t hurt the vehicle after adding more coolant because coolant is 50/50, WATER and antifreeze….You don’t know shit clearly so keep your 2 cents to yourself buddy 😂
@@aiyogarage only reason that it would be necessary to not use water is when it’s below freezing. Otherwise it really doesn’t make much of a difference
My Ford leaks so it flushes itself through twice a year
lol I mean that’s funny. Probably wouldn’t a bad idea to look into fixing those leaks.
The paint is faded on the tailgate of my sticker on my Chevy truck where I removed the sticker of Calvin taking a leak on the Ford logo.
Step one: Stop using green coolant.
