fan doesn't work!
 

2002 honda foreman es, anyway i went mudding and i went in some water that was too deep, it came up to the fender and the quad died on me, so we pulled it out, drain the exhaust, airbox, and carb. its running great now, but the overheat fan won't come on, any ideas?

Try hot wiring it, and see if it works. Then youll either find the fan is junk or you have a wiring/wetness problem. Check the fuses, it could have tried coming on, but shorted out because it was wet...might work again when it dries .

I urge you to pick up the Service manual from Helm or your local dealer, it will tell you how to test what is wrong with it exactly, ie thermostat, fan motor, etc.
