Don't just go and pull your fan and not follow the rest of recommendations.
Yes the kit is $90... which is arguabbly the cheapest bang for buck mod you can do to you car. (right up there with the Cosmo CAI IMHO)
Since its fall you may not overheat your car, but the first warm day of spring.... I don't want to be there to see it
I was able to 'justify' the purchase of the proper equipment for this mod....
1.. I needed to change my coolant anyways.... hence the water wetter
2. I need to swap out my water pump for the metal impeller (might as well change the thermostat too)
so as far as I am concerned, I spent $30 (price of the fan switch) to 'pay' for this mod.
Good luck
