Yesterday, after parking it from a short drive, I noticed the radiator fan still running, and a hot coolant smell. Popped the hood and the coolant reservoir was bubbling, a little bit of steam coming off the rad. cap. The reservoir low in water/coolant. Drips on the ground directly underneath, but nowhere else under the car.
This morning, I check it again, cold. Reservoir a little lower. I fill it up with distilled water to the MAX line. I decided at 80k miles, a good time to change spark plugs & wires. Cheap and super easy to get to, took no time at all. With the water filled up and new spark plugs, I let it idle with AC on, with my infrared thermometer, I tried to see if I could measure a temperature differential between the inlet of the radiator and the exit. I was getting 86.3 - 86.7 degrees throughout the radiator, couldn't accurately measure the inlet/outlet pipes.
Drove around neighborhood, and parked, the reservoir rose up from the max line, to where it's at in this picture.
The top tube going in the tank was HOT, boiling water trickling in, and steam coming from cap. After shutting the engine off, a few minutes later the water level when back below the Minimum fill line. Where it was this morning.
>Has gotten warm about 6 months ago >Water pump and cap changed about 6 months ago No problems until yesterday
Id lean faulty waterpump. Even if its new, it can still be out of box failure

Needs a flush you fucking pleb

Thanks, I will try to see if I can tell if it can pump at all

With the motor completely cold, take off the radiator cap/coolant reservoir cap and start it. Look inside the radiator/reservoir and see if you can see fluid moving. Have you consulted the dealer?

First is that the coolant does not have a sufficiently high boiling point due to poor mixture control. Second is that the cooling system cap is faulty and doesn't hold pressure on the system and allowing the coolant to boil earlier than designed.
Or both I suppose.

Drove around the block again, got accurate radiator temperature readings, at the top, passenger side, went from 190 right after parking, after a bit of idling, went to 210, and I shut it off. The reservoir filled up almost to the top.
Bottom of radiator at both corners, 107 degrees.
I believe this means the water is not flowing. SO either stuck tstat, or water pump is not pumping. What tells the W.P. to come on/ off?
