ok - guys im not searching cuase its too much stuff to look thru



so relaly quick - i bought a fiero efan on ebay



now what do i need to buy and do and whatever to get it to work with the car - i want it to go on and off automatically



so im guessin i need an adj. thermostat for it - and some relays maybe?



i dunno gimme so help

on a fiero they have a thermoswitch right in the coolant, you could reproduce that and wire it into a relay.

yeap.... i have no clue what you mean.... i bought the fan....just the fan....

like on the S4 RX-7's, the thermoswitch in the bottom of the radiator... it's a simple switch that turns on/off based on temperature. Water-cooled bikes use the same setup, just a thermoswitch wired right into the fan circuit. You can just get one of those and a relay to wire the switch to, and have the fan wired into the relay (the fan will pull some amps, probably not what you want going through the thermoswitch, hence relay). You'd have to put it somewhere in the coolant, maybe on the elbow/goose neck over the thermostat. I've seen some people with temp senders installed in the top coolant hose simply by adding a segment of hard pipe in the middle with a boss for the sensor, you could do the same for a thermoswitch.



The other possibility is a temp probe with a thermostat circuit like the flex-a-lite black magic fan comes with... which has a probe you install in the fins of the radiator, preferable if you're not interested in tapping into the coolant system.

this is what i'd do, pull the small fan on the front on the radiator and toss it. Then using those two wires, wire in a bosch relay for your new fan. Should run on the same temp as stock and that way not battle with the thermostat.

argh......thats a bitch to get to....i guess its not too bad when the rad. is out though



thats the AC fan right? the one that goes on when u turn on AC?



or does it go on at a certain temp as well?

i think its temp dependant, i have mine run like that but i have the line to the sensor shorted so that its always on, still not even enough cooling though.

this cooling / summer sucks



ill let you know about my koyo and how it works out for me

I think that fan turns on when the temp is up and the AC is turned on, or something like that. I'd have to look at the wiring diagram to be sure, but if i remember correctly, that fan is wired into the AC subharness.
