There’s a special place in hell for the engineer that designed the 2019 drain outlet

My criterium for coolant change is orange smelly foam on the coolant. Works fine too.

@Ethan-burner-acc says:

WTF??? What ifs it mostly or 100% water?? Or the Evan stuff that can go 300’oC

@Vickyvee97 says:

Stop with the multi metering bs, just get a hydrometer they're only a few bucks and it's straight forward with knowing if you have enough coolant. If you want to know if it's generally in good condition, well is it green or is it the yellow, orange, red (depends on its make )? Then it's good! Why do modern people want to over complicate things?!

@DucomaVet says:

Or just flush it at regular intervals

@allnoyz1414 says:

I call bs… The coolant IS touching ground. There's no source of potential to measure from ground-to-ground.
Also…Conductance (measured in Siemens) is the reciprocal of resistance (measured in ohms).
And still, this makes no sense.

The voltage on my coolant was low, so I just added a cup of battery acid to the reservoir and now my radiator it is fully charged.

@thume5976 says:

What would cause the coolant to be below .2 volts?
And could that same reason be for it to be .4+?

@Warnaing-z7d5k says:

a warning of antifreeze in the mouth means that you may have accidentally ingested antifreeze, which is extremely dangerous and requires immediate medical attention; symptoms can include a sweet taste, burning sensation, and may mimic alcohol intoxication, so call poison control or seek emergency medical care immediately if you suspect you have antifreeze in your mouth.

The only reason I change my coolant is when I have a coolant leak and I have to replace a hose, or radiator or a thermostat or water pump

@BABLON856 says:

For 400k miles, everything under the hood looks pretty new. Must have replaced damn near everything.

@ReddShyne says:

Bought my 2008 honda civic in 2012 used with 1 owner plus me. Ac runs cold everything works great except the coolant levels. I recently changed the water pump, change the oil, changed all tyres changed the suspensions gave it a new color. The mileage is at 249266 (788.8miles).

@Th3GaMb3r says:

Is he trolling about checking your coolant

@anandbhattathiri says:

Hi

On nov 9 th my mechanic did the radiator/ reservoir drain and filled new coolant in my suzuki s presso. He used 1.5 litre of distilled water and about. 900 ml coolant to fill and he started the engine for a while then said its done and gave me half a bottle of distilled water to take home to refill. As he did not specify when to refill (my home is 2 km away from workshop ) i did not check it and after 3 days i took the car for a 60 km drive (30 km up and down with 2 hr break ) the next day of my trip i checked the coolant level and radiator and found reservoir level at Low and no visible water in the radiator. I had to fill about 450 ml each on both tanks to bring to the Full level. The Suzuki s presso coolant capacity is total 3.7 litters in paper and the mechanic and me together filled about 3.3 liter and after a few more short trips its not filled with that balance 400 liters yet !. My worry is that did i do any harm to the engine by driving 60 kms with 900 ml short of coolant? I did not get any warning light or overheated engine. Any harm to the head gasket / pistons etc etc.? Please help for my peace of mind

Thanks

Anand

I'm not going to doubt a brother with 407,000 miles on a Jeep.

@JovanyAcosta-z8b says:

First of all, that’s not a part it’s fluid it doesn’t deteriorate it’s just gets contaminated

@ayush_dwr12 says:

I'm sorry 390K MILES??

@osmanmousamusic says:

Where can I buy that multimeter?

@Anonymous333-h5n says:

How they get that car to 390,872 miles?
My 1996 ford explorer V8 5.0 have 260,000 miles still running i hope i can make it pass 390,000 miles
