I know for a fact this works! My coolant resevoir was boiling so i knew something was wrong. I stumbled across this video to see if it holds true went outside and tested for a voltage of .17v
What doesn't make sense? Coolant, over time, develops an electric charge and becomes conductive. That's bad because it makes it a route for electrical discharge from electronics.
This makes no sense to me at all... but maybe I am missing something. I am a shade tree mechanic with a degree in electronic engineering, so it's not like I don't get what is happening. Why would the difference in potential between the chassis ground and a random spot in the coolant mean anything? How could you quantify it? There will be major variances with coolant chemistry, block and radiator metallurgy, harness wiring, and others. What could this possibly tell you, and why would the desired reading be consistent between many different vehicles?
Correct, however. What happens when something detoriates more and more and becomes more conductive @@GoingGoneGalt? Right on, that voltage will increase. So you are not wrong, but theres multiple roads you can walk.
You have a valid point. The only way to check is if you have a boiling coolant reservoir. Then you know the there is something wrong with the coolant. I would take the voltage reading of that boiling coolant when the car is cold started. Then compare that reading to a proper running radiator. We as scientists must test these theories to find out.
Is it a red flag the coolant valve replaced on a 15000kms only 2.5 year old car🥺 My Mazda CX5 (bought in Dec 2021 brand new) showing check engine light and coolant valve needed to be replaced. I'm really worried if it's gonna run into more problems😔
@@therottenoneslim hey it ended up being the thermostat it was stuck opened? or closed not sure but one of the two and i had replaced it and now my cars back to normal
If you car has an electric radiator cooling fan it should be on when AC is on. Cooling fan running has to help radiate heat out from the condensor that is taken away from the cabin. This is why you should get cool air from the evaporator when the cabin fan blows air through it's spaces. Also check the outside of your condensor and radiator for debris that may reduce or impede the flow of air. With engine cold, Check coolant level, if low, do a static pressure check with a free tool from advance auto or AutoZone. A great time to look for coolant leaks. Pressure test the radiator or expansion tank cap. It should open at approx. 20 psi (see your vehicle specificity). If aforementioned checks out ok, take to a qualified technician.
Another way to do it is stick your pinky in the oil level pipe and your tongue into the coolant and compare that to the feeling from licking a 9v battery. If the tingle is anywhere less than 18x as buzzy then replace the wiper fluid.
If you need to top off your coolant in a pinch, and you don't live somewhere where it is currently dropping below freezing or expected to, then you can use pure distilled water. Though it is always best to use whatever coolant your car is designed for.
@@WakeUpAmerican000s that is very true, that’s also why I said in a pinch. Because if you are in an emergency situation, distilled water, will at least help get you to somewhere where you can get the proper coolant.
You can if you’ve sprung a leak and just need to get home/to a shop, but you need to flush it afterwards asap. It will cause engine damage, possibly a lot faster than you’d think and obviously if it gets below freezing you’re playing a very dangerous game.
