How to check if engine coolant needs to be replaced

[@WhiffenC]

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.

[@jadinwemette8251]

Ridiculous 😂

[@nikobellic3526]

It’s true I’m the oil level pipe

Coolant Pasta sauce was amazing we can rely on that always.

[@1Deejay7]

For anyone taking this seriously, please don't ever taste coolant as it's highly poisonous 😅

[@bonzo3485]

​@@1Deejay7its not that poisonous but the purple stuff tastes really bad definetly not grape

Fun fact nontoxic, rv antifreeze doesn’t taste that bad.

[@ericjacobsen1569]

They call that mt dew

[@leo959]

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 about the blinker fluid

That was funny like 20 years ago

This is fake.

[@MrEvanShmevan]

@TheAncientColossus what’s funny is how you done a simple Google search, you would’ve realized that this is in fact, a real way to check coolant.

[@flightofthefatman]

Chatgpt says not so.

[@defafa9249]

@@MrEvanShmevanjust look at the coolant and you can tell if it needs replacing , no need to waste time with a multimeter 😂

[@GoingGoneGalt]

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?

[@wawaweweph]

i think when coolant deteriorate more likely the conductivity increases.

[@GoingGoneGalt]

@@wawaweweph But he is measuring voltage, not resistance / conductance..??

[@bachmed00]

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.

[@GoingGoneGalt]

@@bachmed00 Voltage and conductance are two completely different things. This is physics, not metaphysics.

[@leo959]

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.

[@andrewmitchell7592]

Interesting

Cool but what if i have no coolant☠️

[@HenryWalkes]

Please tell me when I car run hot when a c is on I did the head job I change water pump I radiator is over a year old the cap change any ideas?

[@bobdelabourer1307]

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.

[@MrEvanShmevan]

Unfortunately, the best advice I can give you is to take your car into a mechanic shop, because I have no idea what you are trying to speak of.

[@zachwilliamsw]

It’s a coolant electrolysis test.

[@reymundmacabenta1]

Doesn't make sense, the job of the coolant is to cool down the radiator

[@guacre2675]

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.

[@Cat-es9rq]

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😔

Coolant valve?

Simple fix tho don’t stress

[@Cat-es9rq]

yes something wrong with thermostat and they had to replace the coolant valve to fix that

[@thehamierocket2412]

Can I add water

[@MrEvanShmevan]

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]

@@MrEvanShmevan -- Water doesn't provide any lubrication to the water pump, so keep it at least 50% anti-freeze.

[@MrEvanShmevan]

@@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.

[@alexk1108]

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.

i just got my coolant changed and when i run my car it still over beats to 120°c and tells me my coolant levels low , could you kno the problem ?
