1991 245 Turbo, automatic
Okay, I've been looking all day and can't find quite what I'm looking for.
I have been stuck in traffic a few times lately and my temperature gauge has climbed all the way up to red. Seems to come back down just fine if I get some clean air in front of me and can drive for a few minutes. However, when I turn on the A/C even on the interstate with lots of air moving over the condensor and radiator my temps climb up to red again and I have to turn it off. I checked today and my pusher fan does come on after a minute or so of the A/C coming on and I get cold air in the cabin of the car.
This all brings me to my current conclusion. I want my pusher fan to come on when temps climb to help keep the engine cool when I'm stuck in traffic or temps get too high.
I've checked the wiring diagram and it appears that it will only currently come on when the A/C is on and creates pressure. I don't want to do an electric fan conversion.
Can I wire the pusher fan to come on when the engine temps get too high? Seems like I should be able to use a Saab fitting in the lower radiator hose, but I wondered if I could install a radiator from another year/model with a thermostat switch already installed.
