Actually water does perform better than anti-freeze/coolant in dissipating heat, but it boils at a lower temperature and freezes at a much higher temperature, and for these reasons is not used by itself. It used to be used straight, with a rust inhibitor, during the summer months but needed changed for winter weather to an anti-freeze solution. Eventually year round anti-freeze/coolants were formulated than did’t require twice a year draining and refilling of the cooling system.
There is a product called Aqua Clear PX. Developed for the military. You add it to your radiator with your antifreeze. Keeps all scale and rust away for years. Been using it for a long time and never any coolant issues. My one car is a 30 year old Camry. Still going strong and the cooling system is spotless
This stuff WORKS, I watched multiple videos and decided to give it a try. Recently bought 1979 Pontiac Trans Am 20k original miles. Sadly, the coolant broke down over the years and the radiator was rusty, dark brown coolant. Flushed it multiple times, it would get clear and then once closed up, back to rusty coolant. Pulled the thermostat let it flush open, closed it up and added Thermocure. I left it in the car for a few days and drove it. Flush and repeat with a second application of new Thermocure. Same routine, I drained the coolant, filled it up again and flushed. The coolant was clear liquid! I just pulled the water pump which was perfect inside, no rust. I replaced it with a FlowKooler pump and a high flow Edelbrock thermostat. The car temperature is perfect! I am waiting on a replacement radiator to start fresh.
Taking out the termostat before doing this is a clue, did you notice the termostat housing totally clean and the block very dirty is because the cold water close the thermostat and didn't let the chemical go into the block so do it again with out the termostat.
@@dustingeurts7649 i drove around without my thermostat in and i noticed more crap came out of it compared to when i drove me car with it in . Smelt like rotten eggs and the stuff was kinda black .
Great review! As someone who has used the coolant flush from Peak and Prestone for several days as well as home remedies like dishwasher detergent, that is a VERY impressive result and the first time I have seen such obvious results from a product like this. I'm generally not much of a believer in additives, but this seems to be one of the few that actually works.
Had the same issue with mine. I burped the system or so I thought. But it kept trying to just barely overheat. Ended up having to park at an incline and filled the funnel about halfway but I kept the engine running with the heater on this time. Along with squeezing the radiator hose to get all the air out. It took about 10-15 minutes for all the air to finally get out. Great informative video, I was about to buy the thermocure but wanted to see reviews.
Put a CFS 3 core Copper radiator in your jeep xj with a external Haden transmission cooler. Transmission will run hot offroading or towing and raise coolant temp. Replace your auxiliary electric fan with a 1998 or newer 10 blade. I also put a Wix inline coolant filter mounted to firewall. That filter will catch your future rust problem just keep it changed about every 10k miles.
Actually, water is better at removing heat from the engine than coolant. Water just doesn't have any lubricants or corrosion inhibitors and will freeze in the winter. It's also not able to go to as high a temp as coolant. However, any pressurized cooling system will allow regular water to get over boiling without boiling in the block or radiator.
Should flush with no thermostat to get past thermostat housing area. Or at least drill big holes on an old one to get better flow when engine cold or hot. Chuck in a new one at the end of flushing system.
Good thorough flush! I like how you mentioned those (Chunks) that keep flushing out.. with the thermostat housing off remove lower radiator hose take your hose with a rag wrapped around it as to try and create a tight seal and turn the hose up all the way try and blow those chunks out the Block then JUST REPLACE THE RADIATOR don’t mess around! They are relatively cheap and mostly recyclable. Radiators Fatigue from non-stop expansion and contraction.. (yes they do explode) oh and those Chunks? Where exactly do you think they end up? They settle to the bottom of the block and radiator..always Run OEM temp thermostat Temp..and a common funky temp problem is fan clutch going south.
I've flushed my 5.4L three times this summer, and the cooland still looks somewhat rusty, although better than it initially did. No issues with the heater or overheating, it just looks kind of ugly. I might try Thermocure next.
Water is the best for cooling purposes. The difference with tap and distilled water is minerals vs no minerals and distilled doesn't create the corrosion problems tap does. Coolant is used to keep it from freezing and conditioning thats it.
That is absolutely not true. It's called coolant / antifreeze. Read the label and you will clearly see it changes the waters freezing point and its boiling point. Racecars use only water because it is not hard to clean up off the track. Coolant is oil based and oil dont mix well with slick tired on a race track.
Using a lower temp thermostat tells the EMC the engine is still cool and will keep the fuel mixture rich. A lower temp thermostat is a great way to kill fuel mileage.
5 degrees wont do much of anything, I have a 1996 dodge ram 1500 5.9l magnum that I'm about to put a 190° thermostat in cause the 195° keeps causing the radiator cap to vent out coolant, the radiator cap isn't faulty, cause I bought a couple and they all do the same. Yes it's a bad idea to change the temperature range, if it was 10° difference I would fully agree.
@@jamesflores9456 Removing the thermostat doesn’t make all vehicles run cooler. It greatly depends on the engine type, vehicle weight (or load) & how it is driven. Many older in-line 6-cylinders will run ABOVE normal temp if the thermostat is removed. No telling on a Camry. If the ECM detects the engine is below a specific temp, it will adjust to a richer fuel mix, IF it’s working properly. My 2016 4-cy Camry averages over 33 daily driving (which is quite a bit of 2 lane @ 35-55 mph) and gets over 36 on all highway (70-75mph).
@@A1rs1ck Might not matter on your specific vehicle, but you definitely have some other problem. A LOT of vehicles will run well over 200 degrees in stop & go traffic with no pressure release. If the 195 thermo is the stock value, it’s not what is causing the pressure release. There’s another problem causing excessive cooling system pressure. The 190 thermo might resolve the issue (for a while), but it’s not fixing the actual problem.
@@remusredbone1214 The big risk of removing a thermostat is that the engineered flow restriction the thermostat creates forces the coolant to to flow around the back cylinders. Without it you can cook the back cylinders all the while the temp gauge is saying all is a-ok.
As some others have pointed out, pure water is actually the best at removing heat from the engine. "Coolant" is a bit of a misnomer. The "coolant" that engines are filled with is actually a 50/50 mix of water and antifreeze. The water is the coolant and the antifreeze is there to prevent the water from freezing in cold temperatures. The antifreeze does also help prevent the oxidation of iron in the engine which causes rust. People who live in warm climates will often fill their cooling systems with 100% water since it is so cheap (although only distilled water should be used.Tap water and bottled water that has not been distilled will result in mineral deposits that negatively affect cooling performance and the longevity of moving parts such as the water pumps.) Using 100% water is very effective at cooling the engine but will lead to internal rust (which is not good for cooling). To maintain a good balance of cooling performance and mechanical longevity you should always use a mix of distilled water/antifreeze somewhere between the range of 70/30 to 30/70 water/antifreeze. Warmer climates should use between 50-70% distilled water while colder climates should use 50-70% antifreeze. Only the coldest climates, that regularly reach double-digit negative Fahrenheit temperatures, should use 70% antifreeze mix. Most people will be perfectly happy with a standard 50/50 mix.
Water is a better coolant than any antifreeze coolant on the market. But unfortunately it causes rust on it's own. And it freezes. So therefore the need for coolant antifreeze mixes
I have always just used a couple gallons of White distilled Vinegar and distilled water. Add the vinegar and top off with the water. Run it for a good 10 minutes and let it sit all night. The following day drive it around for a half hour and let cool. Then flush system with tap water. When done rinsing with water allow to empty before topping off with anti freeze and distilled water.
If you're going to be doing a long flush like a few days to a week, leave the thermostat out.. Do it in the spring, while there is no danger of freeze, and you don't need your heater.. While driving keep the heat on full hot. This will keep the flush running through your heater core.
@@cebayne he was referring to the incorrect statement made in video.... the only reason why water is not use as coolant in vehicle ...are mainly because of rust an expansion when freeze.
Water actually works better than antifreeze at keeping motor cool. It just freezes and doesn’t prevent rust. And 195 is the correct temperature. That’s what temp it was designed to run.
Antifreeze will raise the boiling point of water a little bit maybe by 25 degrees. But having the system pressurized by your radiator cap puts the system under pressure which increases the boiling point well above the 212 degrees at which plain water boils.
I think the reason why the cast iron turned black is if the Thermocure has phosphoric acid in it that's what it will do. Just like rust converters that contain phosphoric acid turns the rust a dark brown or black color.
Thanks for the video. Not many guides out there with systems as bad as this one. I just got a s10 with the 4.3 and same issue . Never seen anything like it before lol. Going to take some time to fix.
Never use tap water in any cooling system. Use only distilled or reverse osmosis water and your system will thank you for it. I would even use distilled for the cleaning procedure. The problem with tap water is the dissolved calcium and minerals in it. Have been doing this for a couple of decades and it works.
About your overheating issues. Get ride if your electric fan and put on a manual fan with a thermostat clutch.. most all of these jeeps get hot with electric fans
Coolant doesn't transfer heat as good as water. Water doesn't fight freezing like coolant (ANTIFREEZE)...get it ? ANTI freeze. Moreover antifreeze has lubrucating properties to help the water pump. Thats all.
@@Pondsisawesome124 Great advice ! Some folks forget that if you change some parts connected with the fluid, the rust prevention is gone (with the old parts). . . so the new parts rusting even stronger . . .
I think your oem thermostat temp is supposed to be 205° Fahrenheit? My 1987 4.0 Cherokee temp gauge wouldn't come all the way up with a 195° thermostat.
Great video man. I mixed the wrong coolant on my Jeep GC SRT 2019 and now it is overheating. There are plenty of brown sediments inside the coolant reservoir eventhough I flushed it. I found some sort of very strange rust inside de thermostat hose. I am thinking that the chemical reaction has also rusted the internals of the radiator eventhough the internals of the water pump look ok. Do you think Thermocure can help?
I would give it a shot. Just be sure to flush out the entire system as the last thing you want is for thermocure to react with the coolant that’s in there. Thermocure should help it out as long as it is rust, and not something else.
Thanks! The setup I have is one end going to the water hose, and the other two ends is connected to the heater hose going from the thermostat housing to the heater core
Evaporust would probably work but if you ran the engine at all it would likely just evaporate, plus evaporust might eat away at the rubber hoses and other parts. If your going to use thermocure I would recommend leaving it in there for a few more days than recommended to get as much rust out as possible
My coolant is brown from the rust. I’ve done 2 flushes so far. Once with blue devil and another with a different brand can’t remember the name.. block is rusty still from when an old mechanic from 2 years ago put water from a hose in my jeep. Do you think this will help bring back normal coolant color?
Did you get some black soot like substance in the radiator after running the jeep with regular coolant? I used this stuff, did multiple flushes and this black soot came around after driving a couple hundred miles with new coolant. I'm wondering if it's the black stuff you mentioned in the block. I flushed it again and it hasn't come back. Guessing I must of not flushed it 100%
THERMOCURE is $140 on Amazon!!! That's a lot. I used distilled water. I flushed it 3 times driving 2 weeks between intervals. Distilled water is cheap. Don't use tap water.
Does this stuff work for soaking the heater core to flush it out? I want to use a chemical solution but I don't want to eat it away at the aluminum and have it leak! 2007 Ford Edge.
I left in it for 4 days & drove it for a couple hours total with it in there. It's mentioned in the video briefly. Just follow the instructions on the bottle & you'll be fine:-)
@@Pondsisawesome124 I ran it for two days and my system. I left my coolant filter on that I run in line with my heater hose. I was blown away with the crap that got filtered out in that filter. I bang it out and rinsed it out at least a dozen times and it still kept pouring out rust from the filter. Definitely works good, the best one I have ever used.
😂 You can't EVER rely on reviews anymore. Nowadays, as a side hustle, people actually get paid to make false positive reviews. And if I'm right, most owned manuals do not recommend putting any rust additives into the cooling ystem due to possible radiator clogs. They suggest if you insist on using any type of additive during a0 flush, it should only be the type of a recommended cooling system c
This was NOT sponsored, I bought the product based on need at the time & it worked to my satisfaction. I'd use it again in a similar situation - your mileage may vary....
I personally don't think that did anything. All it did was turn the rust black. All that gunk will still flow through the system and kill heater cores and radiators. The only way to really clean out the block is to remove it, strip it down and hot tank it at a machine shop. Not always feasible for some folks.
Well, I have to go for a colonoscopy and I hate the crap they gave me to drink, so, since I’m use to take Theraflu for a cold and it works, I’m going to use this stuff to flush my intestines. P/S… I was told that this world is full of STU.PID PEOPLE, and letting them know that I’m joking, is mandatory. Thank you for sharing your video, I’ll try that… ON MY CAR.
"We have to be careful, water does not dissipate heat as good as coolant does"??? Hahaha!!! Nothing dissipates head better than water! "Coolant" is additives, prevent corrosion and prevent the water from freezing. You have NO clue what you're talking about. At all.

You may have a clogged radiator, also check your ignition timing.
Bad thing about Thermocure is I cannot find it in Turkey.
Drill a small hole in the flat of the thermostat, lets all the air out of the system.
Good idea as some Japanese cars have a hole or "rattle" valve from the factory.
@@Pondsisawesome124 YES, but make sure you put hole at the top of the THERMO. HIGHEST POINT.
Does this stuff work for soaking the heater core to flush it out? I want to use a chemical solution but I don't want to eat it away at the aluminum and have it leak! 2007 Ford Edge.
I never tried that myself, I left the core in the vehicle and with the heater on some would have gone through it during the process.
@@Pondsisawesome124 did it work to clean out your heater core and restore heat?
where did you get the yellow adapter that is on the radiator opening? That's a great way to reverse flush the system.
That was from a Prestone flush & fill kit that I had laying around. Most auto parts store should have them.
مفيد جدا، سأجربه قريبا
great video. how did you make that 3 way hose and what is that spicket coming out of the rad? where did u buy that? Thank you!
I beieve both were from the Prestone flush N fill kit in the description & here: amzn.to/3veW3O0
@@Pondsisawesome124 thank you ! Did it come with the clear tubing to connect to thermostat housing ?
Invest in some white vinegar 9% concentration and see the result!
Do I close the cap or leave it open when I let it sit
Sorry for the late reply. You put the cap on when you leave the thermocure in the radiator
So did it run cooler after that?
It was preventative at the time since the Jeep was sitting so long before I got it.
Wow you cooling system is very clean, next step is to clean the whole house drain system
That upper rad hose needs to be replaced !
Excellent video
Thank you very much!
Thermocure /evaporust did not work for me and I drained coolant added distilled water and this product, so be carefull don't be fooled.
you can amke a filter and remove the sand..sand is no good creates erosion
How long did you rub it with the thermocure? I’m sorry if I missed it if you said it.
I left in it for 4 days & drove it for a couple hours total with it in there. It's mentioned in the video briefly. Just follow the instructions on the bottle & you'll be fine:-)
@@Pondsisawesome124 I ran it for two days and my system. I left my coolant filter on that I run in line with my heater hose. I was blown away with the crap that got filtered out in that filter. I bang it out and rinsed it out at least a dozen times and it still kept pouring out rust from the filter. Definitely works good, the best one I have ever used.
I was expecting better results. I guess a high price mechanic will charge me to replace the heating core and flush the systems
where did you get the t thing and the other angled part?
Those came out of a Prestone "Flush and Fill" kit I had lying around. They're cheap at any auto parts store.
😂 You can't EVER rely on reviews anymore. Nowadays, as a side hustle, people actually get paid to make false positive reviews.
And if I'm right, most owned manuals do not recommend putting any rust additives into the cooling ystem due to possible radiator clogs. They suggest if you insist on using any type of additive during a0 flush, it should only be the type of a recommended cooling system c
This was NOT sponsored, I bought the product based on need at the time & it worked to my satisfaction. I'd use it again in a similar situation - your mileage may vary....
Didn't look like it worked very well to me.
Don't put in a lower thermostat 195 is the right one for it
I personally don't think that did anything. All it did was turn the rust black. All that gunk will still flow through the system and kill heater cores and radiators. The only way to really clean out the block is to remove it, strip it down and hot tank it at a machine shop. Not always feasible for some folks.
The best remedy for this is to get a brand new car, exact make and model. Not always feasible for some folks.
Always remove your thermostat first.
This guts a schmuck. Why the heck would ya put thermostat back in while flushing?. Water won't cause engine to overheat.
Oil does most of the cooling. Add a oil cooler
No, it does not.
Oil lubricates lol
Oil
Cleans
Cools
Lubricates
Seals
So oil coolers definitely help in a couple way.
THIS IS WHY YOU ONLY USE ANTIFREEZE AND NEVER EVER TOP UP WITH WATER!
AND CHANGE ON TIME THE COOLANT!
Well, I have to go for a colonoscopy and I hate the crap they gave me to drink, so, since I’m use to take Theraflu for a cold and it works, I’m going to use this stuff to flush my intestines.
P/S… I was told that this world is full of STU.PID PEOPLE, and letting them know that I’m joking, is mandatory.
Thank you for sharing your video, I’ll try that… ON MY CAR.
THIS IS WHAT HAPPENS WHEN YOU ONLY USE WATER AND BE CHEAP!
Clr works better
Chelation.
I'm assuming this will also work for vehicles owned by heterosexuals.
😁😁😁
YOU HAVE NO IDEA WHAT YOU ARE DOING
"We have to be careful, water does not dissipate heat as good as coolant does"??? Hahaha!!! Nothing dissipates head better than water! "Coolant" is additives, prevent corrosion and prevent the water from freezing. You have NO clue what you're talking about. At all.
I hear vinigar is better and a lot cheaper
