I just replaced my thermostat, hoses & coolant. Engine temp comes up normal. Heater works fine now. But I can't get the carb to set back to a low idle even after its up to operating temp. I have made no adjustments to the carb.84 Z28, 305, carb, auto. Prior to this work it would set back to a low idle after warming up. Any ideas or comments? thanks.

 

Are you sure you got a thermostat with the right temp range.

 

Great question. I'll have to double check that. Thanks.

 

did you possibly disconnect a vaccuum line? i had the same exact car and i recall there being lots of hoses and stuff right around the thermostat housing area...

 

there are quite a few lines around the thermostat housing. I was pretty careful to re-connect, but I will double check. Thanks for the input. What is the proper operating temp for the thermostat?

 

I am not sure i don't have the book in front of me but i think it is 195 deg

Yeah it's 195 but the the perfomace thermostats heat range are 160and 180 just at the one's i looked up

 

Thanks for the info.
