Chevrolet Lumina LS, 1996 with 95,000 miles. As best as I can tell the electric fans for the radiator never come on. While driving the temperature seems to stay in the low to mid range of the gauge. If I let it idle for awhile (> 5 minutes) it starts to drift to the high end. I also believe it may have small leak somewhere along the intake manifold. How do I determine where the fan problem lies? Is it a bad thermostat? I read on one of your posts that the fan should come on at ~220 degrees. Where is the sensor and how would I check it? I checked for fuses but only found a relay for each one. I'm not sure how to check the relays?
