this is my first time on this forum, i was refered to come here from a car buddy of mine... i'm havin problems and i'd like to hear and suggestions or advice anyone might have.
i have a 92 firebird, and it all started with my fan belt shreading and overheating real bad.... now, the radiator cooling fan won't turn on till around 250 degrees. i bypassed the relay to make sure the motor was still in tact, and it was, so i replaced the relay, and it still won't turn on til real hot. other than that, i keep overheating on the highway... so there's another problem as well. i replaced the thermostat because there was no pressure in the big hose that goes into the radiator... still it's getting very hot very fast. any input is much appriciated.

 

a search will turn up some things to check, also read this, lots of great info there.

be sure you have a good radiator cap, for your fan coming on at such a high temp, check your fan switch.
for the overheat on the highway, make sure your air damn is on the car & in good shape
