I have never actually seen it working, it is always one that turns on cools off the engine. Is it supposed to be this way or it needs to be checked?

It is linked to the AC

it runs when the A/C is on. Draws a constant flow of air thru the condensor to improve cooling.

You are quick Jetman!

 

[Rosko]

very quick, both of you
My AC doesn't work too so I guess that explains the fan. Thanks!

Family is in the kitchen carving pumpkins! Kids and knives making me cringe so I thought I'd hide out in the office here at the back of the house and keep an ear out for bleeding finger screams!

Saabs are good ambulances too

My oil cooled turbo does sound like a siren!

I just spoke with one of my mechanic friends about this today. It kicks on when the the temp gauge hits 3/4 without AC on.

I'm assuming that the main cooling fan is the one on the intake side (drivers) so if I wanted both to run when the main fan runs I could just splice a power wire from the main fan to the aux ( A/C fan) does this sound right?

 

[jetman]

The main cooling fan is on the exhaust side. I think you have it backwards there. And yes, you can just splice the wires together if you want. Although it shouldn't actually be neccesary with a properly functioning cooling system.

Make sure it's not broken - they wear out quit quickly with the a/c being on....

If it is broken, fix it, as the a/c heat exchanger in front of the radiator tends to reduce the air flow.

Ask me how I know!

There are several different iterations of the auxiliary cool fan wiring, each working slightly differently. That's why there are a variety of answers every time the question comes up.

I would avoid simply wiring the two fans together. The fuse and wiring were never intended to take a doubled load.

 

[DanF.]

Good point... I may just wire up a manual switch like some others have done.. ( btw I have no a/c, had to make room for fmic )

 

[jetman]

That's a good plan. Or at least better then just wiring them together. Its not something I would want kicking in all the time. I might flip mine on a few times a year at most.
