Jaym14,

The taurus fan has three wires. One for ground, one for low speed, and one for high speed. Is the fan wired for high speed?

Yes it is

yeah my buddy said he has seen many autometer gauges reading wrong. I thought this was my problem as well , but my meeter and my FAST (EMS) read about 5 degres appart.

Yes for some reason my DCC controler did not send enough current to the fan, it was probably my fault, so I dont want to say the DCC didnt work b/c it did and there are many people that are happy with them. BUt with my heat soaked bastard engine just having it directly wired up to the high output of the fan it works like a charm. I even tried a pusher fan, water wetter you name it. I also dumped out some of my coolant because i could not remeber if i used 50/50 mix or straight coolant. I put a gallon of distilled water in and it also helped the temps drop alot faster than they were. it took me about 2 years to figure all this out. I also choked the bypass on the water pump down a bit so it would force more water into the radaitor.

It seems that I'm also going down this road of trying every conceivable thing....
Anyway, I haven't messed with the car in a few days, weathers been crappy and I needed to get my mind off of it for a few. I'll get back at it this weekend and post an update......

Dave, did you have the aftermarket gauge's sender mounted in the t-stat housing? That can cause some strange readings because the stat opening and closing can affect the flow of coolant over the bulb.

For the OP, as someone above noted, I would run the fan hotwired (fused) to the battery just for comparison's sake. Just drive around the block a few times or whatever, and let it sit and compare how hot it gets vs now.

Nope, had it mounted in the intake where the stock sending unit goes. Reads consistently with the stock sender and gauge, although I have no idea what the exact temp numbers are that way; with the Autometer or even the cheap-o Equus mechanical gauges, I get either nothing at all or a proper reading that periodically drops out to 0*F and back again at random times. Seriously, my car is haunted or something.
