Engine Cooling problem
1998 Pontiac Sunfire 4 cyl Two Wheel Drive Automatic 156000 miles
The car has 156,000 miles on the frame; however, it has a new motor in it with 70,000 miles on it. I bought the car with the blown motor, replaced it with a new motor only to notice once it was together and running that it would over heat. We replaced the radiator, the cooling temp sensor and have checked the compression on the head and everything tested ok, however, the car was still over heating. My determination was that the fan was coming on only when the car was in park & idling. When in drive, the fan would never come in what-so-ever. Never did know the real cause for this; however, I would like to because right now it's hard-wired to run all of the time whenever the car is on. Oh yeah, all of the relays for the cooling fan was replaced along with fuses. Thanks in advance.
