Little confused on stock fan control....

[Drift_SM]

Alright.

Car has no over heating issues.
It only has the engine fan on the passenger side of the radiator.
I remove all AC components from engine bay, only wiring remains intact.
Im using a 180 degree T-stat. O
On the highway averages 195*
In town it averages 210*

Goal: Fan conrol at any temp for quick cool downs at the track...and driving around town.

Question is: Instead of hooking up the relay bypass and toggle switch...couldn't I just use the factory interior A/C button as a fan switch?

*from what I've read the Engine fan and A/C fan should come on regardless of engine temperature.*

Lets hear it wise men....I know you've all been through this.

When I removed my a/c i left the a/c fan in, so the fan on the passenger side comes on normally whenever temps get high like always, but when i want a quick cool down i just push the a/c button in the car and the a/c fan comes on whenever i want. I would imagine you could wire up the pass. side fan to run off that switch somehow as well.

Yes you can this is what I did, http://www.dsmtuners.com/forums/bolt-tech/238260-how-do-fan-rewire-bypass-after-c-removal.html

When I push my AC button once (orange light), the passenger side engine fan comes on. When I push it twice (green light) the second engine fan (AC fan) comes on as well. This is with the AC/Heat fan speed selector knob anywhere except in the off position. I have no idea if this is standard for 1G's but it was like that when I bought it. Does it work that way with all 1G's?

btw I'm a new member and this site is by far the best DSM site I've seen. Thanks!

OP,

although this does not answer your specific question you may separately want to consider eliminating the hi-lo radiator fan speeds so that when it kicks on it is at the highest speed setting. See: http://www.dsmtuners.com/forums/articles-electrical-wiring/233644-fan-wiring.html

Also, you may want to consider replacing the stock temperature-rated thermostat (IIRC its 180 or maybe even 190) with a 170 degree T-stat. Notice I said replace, not eliminate. "Stant" makes a 170 degree thermostat which fits our cars and its part # 14077.

Prior to the t-stat switch my temps ranged similar to yours which I felt were a little too high for my comfort. Maybe they are perfectly fine but my htinking is long term its better to consistently be within temp specs but preferably on the mid-lower side of same. Since the t-stat switch my temps now range from from 189-192 (very, very rarely reaching 196) in city/stop and go traffic to 189-186 on the highway.

Aside from the t-stat I also have the hi-speed only fan re-wiring, two 10" slim "pusher" fans mounted in front of the A/C condenser which are on whenever the engine is on, and a fluidyne radiator with two 12" "puller" fans. The 12" fans are controlled by the ECU and come only whenas needed. I have a pretty large Greddy Big 24 FMIC which is a major obstruction of airflow in and of itself. Even with all the above though my temps were still a bit on the high side like yours seem to be until I put in the 170 degree t-stat.

Good luck with the heat management issues, hope this might help a bit.
