Water vs Coolant Temperature Test. Which One is Better

[@frankj4212]

Don't use tap water, use distilled water to avoid rust in the future.

[@babybeast693]

It's quite the opposite. Distilled water can readily absorb oxygen and minerals due to lack of minerals, so it will rust faster

[@JeremypoythressPoythress]

Its nice to have a good prediluted balance of coolant and distilled water. I keep a mixed jug of water wetter, distilled water, and coolant laying around to prevent overheating or if i need to top it off. too much of one or the other can cause overheating,freezing or corriosion, because it changes the boiling and freezing points.

[@TreeE30VeRT]

I run deionized water and water wetter and i get a solid 10 degrees less than coolant and we have highs of 115degrees here and i never get past 210 degrees even with the ac running in stopped traffic you just have to change it every oil change or less

No. I live in really hot country and my car is parked under the sun all the time during the day. The water doesnt dried up that much. Plus, its not hard to get water

Water doesn't evaporate or "dry up" in a closed system. If you poured water on the sidewalk it would evaporate, but so would coolant.

[@2oswalds]

I always wished these kind if comparisons used engine cylinder or head temp because the best coolant type/additive, which draws heat away from the engine most efficiently, will paradoxically heat up your coolant and coolant temp sensor the most. At least initially, until it’s improved heat transfer ability results in radiating heat out away from the coolant faster- which itself could be skewed by the other variables of thermostat and radiator fan.

[@2JZLS]

Hey heres a potential idea: “Drag-Racing Coolant” Does your local track require the use of water as engine coolant? Do you want to daily-drive / park your vehicle below freezing level? If you answered yes to both, this product was made for you. (Am i onto something? 🤷‍♂️)

[@usmanghani2371]

What is the method of using coolant in a car that has been using ordinary water for a long time and would it be correct to put coolant in it? Our area is hot and humid. The temperature here is never less than ten degrees Celsius. It is generally said that a car that has been using water for a long time, if coolant is used in it, will cause rust and disturb the engine of the car.

[@CarModsGarage]

Hmmm interesting. I would think that water causes rust and the outside temperature doesn't matter much since the engine and the water/coolant will get got anyways. That happened to me before when I took the old rusty coolant on my carbon Brazil and flush the system it took rusty spots that were covering or preventing water from leaking so it started leaking. It would leak eventually anyways. So in short water boils with lower temperature than coolant. Coolant has things in it that prevents rust. I can't tell what will happen to your car but if you been running for a long time anyways and it doesn't overheat there is no reason to replace. Check the color of the water though. I bet it is rusty

[@dnegel9546]

Technically water is actually better at cooling then coolant. The problem is water does not lubricate the internal parts. This is where an additive like "water wetter" comes into play. It makes the water cool even better while also adding all the lubrication you need. Alternative you can do a mix of more water then coolant. (70/30) or so. Most race cars use plain water. Since most tracks ban anything else. For safety reasons. (Clean up etc.)

[@hellohello8556]

If your running exsreme temps use distilled water with 33%coolant the coolant and distilled water will stop rust and cavitation and also the coolant will lubricate your water pump. Unless your car runs hot just go with 50%coolant and 50%distilled water.

[@Annsweets]

Is it fine to change mind from distilled water to coolant ?

[@CarModsGarage]

Yes idistilled water is good since it doesn't have all the minerals . The only catch for distilled water is if you live some place that gets at or below 32 degrees F it will freeze. If not keep your distilled water

Thanks & best wishes for your future videos 😊👍

[@CarModsGarage]

Hey John, I appreciate the support 🙏! Yes if you use the concentrate coolant you should use distilled water to mix. Usually I get the 50/50 so I don't need to worry but yes mix 50% of the concentrate and the other 50 with distilled water and you are good to go. 👍

[@blueballsbkueballs]

@@CarModsGarage I guess the quest is " battery top up water " as distilled water. Answer is Yes, actually battery top up water is deionised water not distilled water. Out of two, deinoised water is better to mix antifreeze because it doesn't absorb iron from engine metal like distilled water, though the difference is not much in practical but from a scientific perspective.

Someone told me that use pure concentrate collant without water.so it is good or bad for my car to use 3 liter coolant without mixing water.

[@nilsfrahm1323]

I think the coolant boils at much higher temps, like 160C, so your water is boiling at 100C, causing more pressure and wearing out the system. You should add some coolant. Coolant lubricates parts and boils at very high temps, so in normal use it will not boil. Also it prevent freezing unless you go lower than -20C or even -36C (depending on mix ratio with water).

Gotta use coolant unless you are on the track and they don't allow coolant. If your car overheats with water there is a very good chance you have a problem so it might overhear with coolant also. Water was on my system for around 2 months. Driving very little and the water came out rusty. The temperature the car was running was higher but not overheating. Switching to coolant after 4 months the coolant is the same color so it sis not promote any rust. Car runs a bit cooler for longer. The fans will kick in at certain temperature so regardless of water or coolant mine at 176F will run the fans.
