Well my fan actually has worked all along since I rewired it per the original '86 wiring diagrams. I just had to wait longer 'till it got hot enough. That's the new problem, though. In my '86 shop manual it says it should come on around 220° or so. Problem is, my fan doesn't turn on until it gets to the white line just before the redline on the coolant temp gauge. I assume that white line represents 240°? The fan then remains on until it gets down to 220°, then shuts off. Now I've heard a lot of things...one that the temp gauge could be off...and it's really turning on/off at the proper temps. I've also heard you can go buy another chip or something or other that will let the fan turn on at a lower temp than it is. I've ALSO heard that the coolant temp sensor could be dirty and therefore "thinking" it's at a lower temp. What do you think? It doesn't bother me much as long as letting the car run up to that temp doesn't hurt anything. Does it?

 

another thing to think about is actually how acurate is your dash guage anyway....will we ever know?
