Dude, my car died in Lakeland once - my alt. belt shredded apart.
Anyways, don't rely on the OEM stock sensor man.
I have one fan on when ACC is engaged or car is running. Run power off the LOW FAN RELAY in the fuse box.
Other fan is engaged w/ A/C. I'm thinking about wiring that A/C line in-line w/ the OEM temp sensor.
Keep the KA-T alive
