I've been meaning to fiddle with my fans for better cooling on my 94 sc....today i did some rewiring and managed to connect the pusher fan on the outside of the radiator to a switch inside the center console hoping that it would help with cooling.
The RESULTS:
Unfortunatelly the fan is either too small or the 'pushing' action is not as efficient as the 'pulling' of the big fan...nontheless, the fan really does nothing for cooling when the engine is opperating. The temperature continues to rise even when the fan is on the whole time. It does somewhat cool once the engine is off, but not while its running
CONCLUSION:
Im going to try and see if its possible to turn, or reverse, the fins on the fan and re-test to see if there is any difference. If not then I will spend countless hours pondering as to WHY IN HELL ford decided to put a pretty much obsolete fan on these SC's. The only thing that I see from this fan is rewiring it and using it to cool the engine at the track or something.
Attached is a lil diagram i made while doing my hw on the fan which explains the factory operation of the pusher fan. One small correction: the pusher fan relay is mounted directly to the fender on the (facing the engine) top drivers side corner of the engine compartment (next to the brake booster & clutch fluid reservoir on 5speeds) , not inside the wheel-well like the diagram sais. Its a small black relay mounted on a metal frame.
