electric fan????
« Reply #30 on: July 11, 2011, 12:30:30 PM »
just read the thread and looking to ditch my aux fan.  i already ditched the clutch fan running a lower temp switch and water wetter also running new temp gauge sender.  the car runs pretty cool but hits about halfway sitting traffic.  i would love to put a 14" in the front where the aux fan used to be and a 16" puller behind.  i was wondering how the wiring would be on that.  i would like the aux to turn on with the low temp and have a separate switch which i can control for the puller 16" is that possible?

Well you can use the aux fan wiring to control the 14" like I do. Basically works like stock just pushes more air. Regarding the 16" puller, can you try to wire it to the same wiring but that will probably overheat relays and fuses.  I would suggest you just run 12v to it from a source, and add switch.

i was going to add a switch for the 16 inch puller.  where would you suggest for the 12v source??

In the front of the car you don't have have too many choices for 12v. You might have to pull from the existing aux fan circuit for constant 12v. Other option is from fuse box, you just have to be careful which fuse/circuit to pick from.

Or from the junction block on the passenger firewall, where there are a couple of bolts you can loosen to put a connector on, then fuse it and thread it around to the front, which is what I did. I used the existing aux fan circuit to trip a relay whose power comes off the junction block.

that is correct. The radiator closes to the is the radiator, the other, which is smaller and has AC lines going it, is the condensor. Only needed if you have an AC system. You can remove it. Just make sure the system has no gas.

Will not blind you,if it did get into your eyes just wash it right away.

Happen to me before and I did suck up all the freon out before removing condenser.
