hey guys, i am having trouble with my 90 gxl cooling fan because it wont start and is causing the engine overheat so i took a look at it and the fan is good but the wiring is not attach to anything other than the relay...

so as u can see in the huge pic (sorry about that) there are 2(black and a red) wires from the fan to the relay and then 2 red wires from the relay to ????
i know the red on the right goes to the pos on the battery but cant find the conection to the other which i connected to the negative and didnt do nothing, i let the car run for like 10 min and the fan didnt start..

here are a couple more pics so u can see better whats going on and help me fix this so i can drive my fc again ..

you'll need to trace the wires back to find out what is powering up or grounding the relay to activate it. is the battery relocated or just out of the car?

Out of the car for now

plenty of aftermarket fan wiring diagrams in this thread to use in wiring up yours

Your fan cools your car efficiently? Looks a bit too small IMO. I use a taurus 2 speed fan with the low speed always on, and the high speed controlled by a thermoswitch. I can't recall what the wiring diagram is exactly, but 4 or 5 pin relays are fairly simple to wire up. One to 12v power, ground, 12v switched to activate the relay, and the one providing power to the fan.

That fan looks a bit to small to be efficient in my opinion. I have the above mentioned Taurus 2 speed fan I'll sell for cheap with a 30A relay and a 30A Bussman auto circuit breaker. I can include a wiring diagram as well. PM me if you're interested.

Put the stock fan and shroud back on. That fan wouldn't keep my dog cool. Stock fan designed by short guy with big brain.

Bought the car with this fan. I havent drive it much because it had a bad diff but now thats fixed.

i like the 2 bolts holding the water pump pulley on as well... weight reduction.

Yeah, that's not a factory fan. Or even an acceptably sized fan.

Here is a link to how I wired up the dual fans from an MR2 for $20: http://workingtofu.blogspot.com/2008...on-for-20.html

You can get fans from tons of different cars that will work better.
You'll need a temperature control switch for the fan once you get it (if you decide to stick with an E-fan)

Don't drive it much with that fan or you will be rebuilding soon. Stock fan works very well if you can buy one on the forum. Otherwise do the dual fans as in the writeup. Last thing you want is a hot rotary.
