I have a 2002 Raptor 660 and i don't think the radiator fan is kicking in.. i havnt actually got out and steamed it up really hard but let it warm up well enough for it to have kicked in, and it just doesn't. is there a way i could test it? or what other problem could cause it?

ive heard thermal switch, and also heard its very unlikely to go bad.. what should i do? how do i test the fan? how do i know it isn't something else?

 

they hardly ever kick on unless your riding it hard. if you want piece of mind just wire up a toggle switch for it.

 

i had mine only kick in once and it was in summer and ridding in the desert. i also had the same concern.

 

id toggle switch the fan if it were mine. i wish my 99 big bear had a fan on the oil cooler. i have thoguht about changing the cooler to a bigger one and adding a fan.

 

Never had a overheating problem on the Raptor 660. It is pretty hard to get that fan to run. You would probaly have to be working it hard and a slow pace with no air to get it to kick in. Is your fluid overflow full?

 

Same with mine, let it idle for hrs and no fan action. Ride the dunes hard in summer and no fan still. Get a in line temp gage if your worried, or just keep a eye on your overflow bottle.
