Engine Cooling problem
1991 Chevy Blazer V8 Four Wheel Drive Manual 235000 miles
I recently had the engine in my Blazer (5.7L TBI) rebuilt. I initially had some trouble getting it running smoothly, but eventually working with my mechanic, got it running well. HOWEVER, engine seems to run pretty hot (around 210 F) about 50% of the time. The other 50% it runs around 185 F. When it is running hot, there is a noticeable lack of power & it smells prett "exhausty" and rich. I have done the following:
Installed new thermostat
Replaced BOTH temperture sensors (one for guage, one for ECM)
have the same problem?
