can i run one fan

[opendown69]

well i am going with a t3 t4 to4e and i was wondering if it would keep my motor cool enough to run right, specially when my secondary fan wont turn on ever, even if my motor is over heating can i just run one fan?

I am currently running one fan due to having not installed my 6 month old slim fan. It ran fine through the 115 degree california summer with one so I think you will be fine.

im going to take one of the fans and put a push style fan in front of the radiator instead
so I can clear up more room in front of the exhaust mani.

The fan on the passengers side of the car, if it is wired with the original wiring, will come one when the car gets to a certain degree. The left fan is meant only to come on when you turn your A/C on. The reason it does this is because when you use your A\C, the condenser that sits in front of the radiator puts off a lot of heat. In order for the car to run at a decent temperature at idle with your A\C on, you need to fans to suck enough air to cool the radiator and the condenser.

The way i have done it in the past is the wiring for the passengers side fan has a high and a low speed setting. (blue wire, blue w/ white strip wire, black wire, black w/ white stripe wire) I dont remember exactly which one was high and which was low speed but i ran the high speed wiring to a relay and hooked both slim fans to that relay. This way when the car hits a certain temperature, it turns on both fans instead of one. My main reason for doing this was i was running a Koyo all Aluminum radiator which is a lot thicker than the OEM one. The stock fans would not fit correctly with the turbo i was running so i had to buy slim fans. I also wanted the drivers fan to kick on at the same time as the other one so that it could also blow air onto the turbo itself.

I would not recommend a push fan setup unless you are totally in need of space and have taken out your A\C Condenser. The push fan and pull fan setup, with a big turbo, stock radiator, and in hot climates will not work as well as 2 pull fans.

I dont have a/c at all but have both my fans set up to come on full blast soon as the ignition is on and its been like this for a yr now with no problems and seems to help.
Im doing away with the a/c fan for clearance and putting a push fan on the other side of the radiator in its place. Should be ok considering I never really needed too fans anyways.

If you A/C Condenser has been taken out, you should be fine on running one push and one pull fan. Good Luck!

1Gs only use one fan. The other is A/C just like Turk said. One fan keeps the needle dead center. I used to have both wired to my switch and it cooled it down fast. One fan does the job fine though.

So if the a/c is removed, is it ok just to take out the a/c fan and not put anything else in?

Yes you can, your a/c fn only turns on when you actually turn on your a/c. You might want to look into slim fans if you are pressed for room.
