Overheating problem...
I went racing on Sunday and sitting in line to get in the check gauges light came on and the car was at 240 degrees. I quick popped the hood and turned on the manual fan switch on high. It brought the temp down but I can't understand what's wrong.
Do you think 240 degrees fried my Mobil 1? I'm thinking I should change it now.
I checked all the fuses and the fans work with the manual switch. At speed, the radiator and thermo seem to be working right. At 45+ it runs 180, which is normal. When I sit idleing or going slow, the temp climbs. I watched it warm up from 180 all the way to 225 and it never kicks on the fan.
Fan relays burnt? How do I check it? How do they work? Are they energized all the time and ground when the car turns off +12 to them or do they turn on and provide a ground? When I pull them out and stick them in while its running I can hear and feel the relay click. Why is there a fan relay #3?
Please help!
