heating question for 79 firebird formula.

I went out on the highway driving 90 and over for 20 min. Than next day my car is taking forever to heat up and its still, after 30 min, running at 110 degrees. I am not sure what it is? Also the temp here in Co. is around 20 degrees, but i dont think that is the reason.
PLZ. help :banghead:

Sounds like your thermostat may be stuck open or you might not have one.

I think thermostat is stck open, cuz it used to work before. Thanks. I just needed somebody elses opinion. On the other note ( I am soewhat still learning about cars) is the thermostat under the radiator hose, top one?

Yes, you need a 1/2 inch socket and a screwdriver to change it, scrape the old gasket away and torque the housing to "just tight".

My air conditioning belt blew, since the ac just got shut and did not spin anymore. Before that it was messing up my ac since it was blowing all the time.
Anyway, if i dont start the car with heat on it heats up to the normal temp. without a problem. So i think the ac was the culprate, but i will still check the thermostat.
THanks guys for helping out.!!!


P.S. ( I only need to do 3 more things to this car to make it legitimate hot rod).
1. Headers (sounds good, but the car can sound way better)
2. Shocks ( It squeeks when i go up and down :)
3. Air Scoop from Holey ( I think thats what its called). I want it to stick out high, but sticking out a little bit is what i have to go with.
