I know a buddy of mine has a switch on his Integra to keep his fan running even when his car is off to keep his engine cool, does anybody know how to do it on a 2k1 civic? With my header and no cat, my engine tends to stay warm for a pretty long time. Anybody got any advice? Thanks.

The fan running after the car is shut down won't cool the engine any faster, it'll only cool off the radiator. Since the car is shut off the engine isn't circulating coolant so its useless. A engine running hot isn't a problem because there designed to run that way, as long as you're not over heating, I wouldn't waste my time on it.

Damn, kinda bummed out after that. Thanks anyway!

Yeah...solar kinda has a point there.
