1995 Pontiac Grand Am Quad 4 approx 160K
Car is overheating and I have tried everything to fix it, but it still
overheats and I need some advice.
Here is a list of what has been done and in the order that it was done.
1. Fan blower motor was replaced, and the fan works fine, comes on when it
is supposed to.
2. Thermostat replaced.
3. Complete coolant system flushed out.
4. Head gasket replaced (apparently there was a small leak), and head was
for pressure test by GM, and it came back fine.
5. Radiator replaced. New cap on the coolant reservoir.
Also the water pump was checked and it is working fine.
None of these has fixed the overheating problem, and I don't know what else
it can be.
The temp is fine at highway speeds (about 1/4), but as soon as I get off the
highway the temp goes above 1/2 and
it is evident that it will go into the red if I don't cool it off right
away. So I stop and open the radiator and let the steam
out and also coolant comes out as well, but I do it very carefully using a
towel. The fan stays on, and after about 5-10
minutes the fan turns off, and the temp is back down to 1/4. I am so
frustrated because it is costing alot of money for the
garage to do all this, and it's still no better than when I first took it in
over a week ago. If anyone has any suggestions at all,
or has experienced similar problems, I would really appreciate any advice or
comments. To those in the pontiac group that
have allready offered advice previously, I thank you, and I have tried
everything that has been suggested thus far.
