I recently had my 94 Z LT1 serviced in which they had to replace a heater core. At the same time they replaced the t stat. I used to run when the engine was fully heated about 180 degrees and now run 200. is this a normal operating temperature? I checked the bleeder and no air was found....thanks

Do you know what degree thermostat they put in and if it was the correct long style LT1 thermostat?//

 

Not sure but done at Pep Boys. They should know their stuff but I'll check.

 

Yes, you should check.
