Some FCs came with the electric fan in front of the radiator stock. Has anyone disconnected this fan and used the wiring hookup for their black magic fan on the other side? Would this work? Does anyone know what temp that stock electric fan is triggered to come on?

 

Which models came with the electric fan? If they did I never seen one or heard of one.

 

I have seen this in the factory manuals.

I have never seen a factory fan..

tell us which had this?

 

The stock electric fan triggers at 97ºC (207ºF), which I suppose is about right for an electric fan. It would be an interesting experiment to see if it worked. It wouldn’t be a major to change to a separate thermoswitch if it didn’t.
Note the stock fan only draws about 2.5A, so you wouldn’t want to run an aftermarket fan straight off it’s wiring, but through a relay instead. Also the stock temp switch is closed up to the switchover temp, then opens, so you’d need a SPDT relay. Use a 30A automotive relay fed directly from the battery via a 20A fuse. Control the relay with the stock fan’s wiring.

 

just a fan clutch.

 

factory front electric fans were found on loaded GXL and some TII models. A automatic in the car increased the odds of it having the supplimental fan by 50%

 

Thanks guys I think I will be trying this within the next few weeks so I will let you know how it went.
Btw what does SPDT stand for?

 

sold in hotter regions??

 

Isn't standard operating temperature 174ºF? My guage never goes above 190 anyways (sits at just under 180ºF, but climbs when i push it hard).

BTW i have the clutch-type fan.

 

Ignore what I said about that relay, I was wrong. Any 30A automotive relay’s fine. Since you’re using the stock fan’s power supply to operate the relay (not the temp switch directly) it doesn’t matter about the switch being normally closed instead of normally open. Just run the stock fan’s wires straight to the control side of the relay. Sorry about that!

 

Not according to the FSM.
