Most cars & trucks these days have electric fans,with some or most being dual fan setups. They typically come on at 180-190 degrees. On a dual fan setup from the factory (GM) does one fan come on or do both fans come on at the same time? On this 94
GranPrix I am using, just one fan comes on at 190 degrees and the other one never comes on. Temperature never goes beyond 195 degrees. Do I have a bad fan?
