Aftermarket Single fan conversion...
Hey guys,
I was looking in the FAQ and searching around but didnt come up with what i was looking for.
The stock FD has a dual fan setup which weights as much as the engine and looks about as efficient as a dull razor blade. When i pulled my rad/fans out, one fan had 4 blades and the other 5 blades.... the blades were not even radially simetric!!!!!??!?!
Anyways.. i was looking at this fan from summit racing. It has the best CFM:Amp ratio i can find.

How do i hook up this fan to the stock dual plug setup???
Im sure this has being covered many times, but my searches came up with nothing...
Thanks a lot guys.

A.: The stock fans are actually quite efficent and powerful, you'll have a tough time replicating w/ a single aftermarket fan...
B. They are multi-speed and automated for load, so they adjust to conditions better.
C. The 4/5 blade combo is for noise-cancelling, so they are quiet.
Leave 'em along unless you've got a really good reason not to.

I agree with Peter.
However, if you are going to go aftermarket, look at SPAL fans.
Not sure how to make them work with the stock fan relays and such. The next time one of my fans burn out, I'm probably going with a SPAL. Stock fan motors are around $160 each when purchased new. I've burned through 2 used ones in the last 3 years. The electric motors of the stock fans are 15 years old at this point.

here's a writeup dubulup did for me when i was changing my fan setup. just to show you can wire up stuff if you know how. afaik there isn't a significantly better setup than stock.
This new diagram will trigger off the PFC settings...and you can remove the thermoswitch and relay no. 1. and 3.
Now all you have to do is ground the Black wires ("-"; I assume Black) on the fans and splice the Red/Yellow to the Red ("+") on fan #1 and White to the Red ("+") on fan #2. They will both come on at the same time...
hope this helps.
(top row rear and lower row front are the ones you want to keep...double check with the wire colors...you can also consolidate to a single row
)
