Fan Problem Cure
I replaced my thermo switch for the main fan today. First test run indicates that the fan now comes on at 100 degrees and keeps it below that temperature in traffic.
So all of you that seem to be having the same problem should consider replacing the temp sensor.
It costs about 20 bucks more or less, and requires a deep socket of 22 mm. Easy out, easy in, no need to even drain any coolant!
Try it, you'll like it!!
