About a year and a half ago I put in a 160* thermo and programmed my fans to come on sooner.

Last summer the car never got above about 200* in the middle of the day in traffic with full AC. Now that it is hot again, its getting up to around 220-230 in traffic with full AC.

Also, I have noticed that after I drive the car at temps like that, the next morning, I will see a semi-small puddle of coolant in front of the Passenger front tire. Then when I go to start the car, the low coolant light stays on. Then i can drive for a minute or two, shut the car off, and the light is gone upon restart.

I flushed my coolant with new Dex-Cool (50/50 mix) using our machine at work. I checked all my coolant hoses for cracks/leaks. I verified that my fans are working correctly. I have a new overflow bottle, and new hose from the overflow to the radiator. I have a new coolant level sensor. I do not have any oil in my coolant, or any coolant in my oil. Other then the situation above, I have no leaks.

I am sort of at a loss. Everything seems to be functioning fine.

Really the only thing I can think of is that maybe my 160*thermo is stuck open...maybe.

I could really use some help/suggestions guys!

I am starting to get at this problem

Thanks!!

 

Did you bleed the system? Try that, and put in some red line water wetter.

 

Bled both bleeders lol

good idea with the water wetter tho

 

If there is a puddle on the ground, there is a leak or it's overflowing after shut off. Rent a pressure tester to check it out. Have you replaced the radiator cap?

 

pressure tested the cap...functioning perfectly

i know that it is overflowing...just dont know why i guess...
