Hey Everyone! Just purchased another fiero. Its an auto 87gt. It has a slow overheating issue and before I go replacing things. I wanna know the best approach.

Some things to note. I drove it from pueblo to colorado springs 50 miles goin 80 with no problem.

I dont see any white smoke coming from the tail pipes at any time. Engine seems to run strong so I think I can rule out the head gasket.

Normaly, When I am crusing the temp stays around 190.... when i hit a red and idle it quickly goes to 220.

After a 15 MIN ride the car comletely overheated. I checked the resivoir and its pretty ugly. looks almost like a rust color. I don't see any of the coolent lines leaking and the send and recieve pipe are not bent. Where should i start?

Make sure your fan is running, and if it is, make sure it's not "wobbly".

The rust color is probably BAR's Leak. I know my Fiero had that in it and it makes the overflow tank look rusted.

So it turned out to be the water pump. I took the old one off and tried to rotate the pully by hand.... it made a horrible silent squeak. I put the new one in and filled it full of water. Didnt even get over 120 deg without the t-stat on idle/ drive for 20 mins.

Thanks for the help tho.
