I have 2002 Camaro Z28, I'm having some really bad overheating issues with it, just put new coolant in and burped the system. I am thinking the T Stat is bad, what is a good way to check this, also I have gargling noises in the cooling system when I turn it off. Air? Lower hose is cold after driving and upper is super hot.

 

did you drain the coolant to begin with? it doesnt seem like you have it filled all the way.

 

Yeah I drained the entire system, topped off the radiator and the reservoir, I have no leaks. But when I try and burp the system, it will not reach 210, and the coolant just keeps flowing over. Thermostat?

 

Can I take the thermostat out and run the car, also is it smart to take the crossover tube to the throttle body off and run the car?

 

T-stats usually fail in the open position, but it is possible to fail closed. You can pull the t-stat out and run the car for a couple minutes to see if your water pump is working, but I wouldn't run my vehicle without a t-stat for long. Have you checked the water pump yet?

 

Thanks bro, no I haven't checked it out yet. No a good way of checking it?

 

Yes , that t-stat is stuck ,,,,,,,,,,,,,not worth messing with ,,,,,,just repace it and get the air out and You'll be good 2 go .

 

Yeah if your top hose is hot as hell and the bottom is cold, t-stat.
