Engine Cooling problem
2002 Chevy Impala 6 cyl Front Wheel Drive Automatic 137000 miles
Hello I am having a problem with my cooling fans. They Will not come on unless I unplug the temp sensor, Unplug it fans come right on no problem but of cource the temp guage does not work. I replaced the temp sensor hopeing this would be the problem, But no such luck. Also I checked all the 3 relays that a labeled fon cont. And fuses but this checked out as while. Im thinking that the computer reads the signal from the temp sensor and once it sees 210 or how ever many oms it sends a signal to the relays to turn the fans on. I know that the perv. Owner had some cooling problems and had in the shop sevrel times.
have the same problem?
