Is the cooling fan working? If it is electrical make sure the fan switch is working, if not replace it. If the fan is belt driven your fan clutch might be bad. Try Redline water wetter in your coolant which will help the car to run a little cooler.

It's belt driven. I'll have them check it tomorrow. I'm also getting another thermostat in the morning just in case it's sticking. Any other suggestions are appreciated.


If you didn't do it before, have them flush the radiator and engine.


Didn't realize I had to ask them to do that. I'll have them do it when I take it back in. Thanks!

U may want to have them bleed the system u might have air pockets in it


Ended up being the fan assembly. Didn't have a fan clutch. Glad it's taken care of now!!!
