C5 Fan Trick
Get a chance to hot-lap at the drag strip? Hate paying that horsepower penalty when the coolant temp soars? There is a work-around short of a fan switch or tuning the PCM.
All it take is a 6 inch piece of wire and a couple minutes to do the set up the first time. After that about two minutes each time you go to the track. Helpful in the summertime too; keeps the engine temps in the range for good power.
I put up a page at my site with a how-to for turning on the fans without tuning or a switch.

Not without more extensive wiring that I wanted to do.
With the low-speed fans on, I never saw a coolant temp above 195 even on four passes four minutes apart. Most I ever did literally back-to-back at a rental.

WOW,,,you could even solder a small switch in the jumper, velcro it to the relay and just leave the wire in place and flick the switch when you want the fan to come on!
