Coolant temp overheat

[jimim]

That plan was before this happened. So I’ll watch it still and post pics each morning of level. Take it back to them. They said they wanted to leak test it again for some reason. Maybe at that point they will do other tests if they feel it’s warranted if I’m paying.

That test kit should be here tomorrow too.

$180 an hour is always painful , you can buy a pressure tester kit for about $100, that’s what I did when I suspected issues, but I used it twice, no leak, and now it sits with my cool tools I have pile.

I did put in the aluminum coolant tank, as a preventative measure.

That’s all they did for the leak test pretty much? I just did a quick google.

Morning boys yesterday am vs this morning. Bottom is this am. Top yesterday.

Normally leaking headgasket will cause bubbling in the coolant and the car will overheat quickly. I have never heard of a car "eating coolant". They can do a test to look for combustion residue in coolant to confirm its the headgasket or watch for bubbles in the coolant with engine running. I think its more likely there is a leak somewhere and they are not seeing it. Probably a small leak that overtime emptied your overflow reservoir.

Especially since it seems the OP never once checked the level.

People need to check their fluids!!! My brother has blown not one, but two engines due to low oil. Does he check his oil level now? Nope.

yes i have learned. i will now be more way proactive vs trusting otherswhen servicing eve nthough I ask to check ALL fluids. I'm going to wash the jeep today then check the other truck's levels. i'm on it anymore. new years resolution is to deff learn more about my trucks and take care of more on my own. i got a busy life with the kids so it has always been easier to drop off and hop in a loaner and go.

My wife's sister is the same. Here car always has no oil in it. I check when she comes to visit. I always tell her that her Toyota is testament to Toyota quality. Zero maintenance, zero oil changes and zero oil in it, car just runs..

Ok I got the test. Coolant temp is at 212 with engine running and liquid did not change. So am I good or does the thermostat actually have to open to allow coolant to flow through to see if there is a leak in the he head. I hope I’m saying that right.

Pretty sure the thermostat opens at 195 on the 2.0

Ok so should the fan inbetween the radiator and engine kick on? Or if there was a leak I would know by now with it at that temp?

Fan won’t come on until 225, unless you put the ac on max, but I think your fine at the 202 to do the test. The fan on isn’t indicating that the thermostat is open., engine temp is

Shouldn’t they have check [the level of antifreeze] when it was in for service last week? I just went in for oil change and new brakes and literally said to check all fluids. Isn’t that one they check?

The coolant reservoir tank is pressurized. The technician wouldn't be able to safely remove the cap until the fluid had cooled sufficiently to prevent injury. Enough time would had to have passed during the service appt. for said cooling to occur. Unless your vehicle was there for several hours, that's not likely to occur.

As the 2.0T's main reservoir tank is opaque, due to the chemistry of the plastic required to tolerate the heat of the adjacent turbocharger, there aren't any shortcuts here.

It was there 6 hours for my brakes and oil change. Cause I tld them to keep it for the day. . . so yah they could have checked.

Ok so I called it at 212 degrees. No color change. So do I assume the stat was open to allow coolant to be flowing to see if the test was valid? Cause if stat doesn’t open then coolant isn’t flowing to know if there is a leak? Am I correct? Just trying to understand when to know if there was a leak that co2 would be in there to turn it.
