I haven't ridden my rappy much only twice actually, and I noticed that the fan has never came on. Is this okay. The second ride was like an hour, but i wasn't really riding hard i was just wondering if this was normal. I didn't even know that it had a radiator fan until i looked this morning.

 

I don't know the specs on the Raptor, but it's probably set for somewhere just above 200 degrees F. How close am I Raptor guys?

I don't know where the temp kicks the fan on, but if you shut your engine off by using the kill switch on the handlebars and leave the key on, and it's hot, the fan will continue to run with the engine shut off to cool it down some more.

 

I don't think you would even hear the fan if your riding along because its not that loud compared even to the stock exhaust noise, so are you sure it hasn't come on?

Also depending on your areas temp if cool air is blowing through the radiator it might need to come on. I would start the machine up and just let it set there with no air flow and it a short amount of time especially if it has been ridden it should come on.

 

The Fan will hardly ever come on. Mine has been on like 3 times while riding, all while hill climbing on 90 degree days.

The fan comes on mine at 210. Normally while riding my raptor is in the 165 range.

 

I ride w/ guys w/ Raptors and they hardley ever turn on.....and we are in dunes were at times the temp can be 90+

 

mine turns on but not as much as the DS guys,there fan is always on,mine came on a few times...

 

My fan only comes on after continous drags 600-1200 ft ones.... Ill do them over and over maybe like 10 times down and back (20) withought a break, keep in mind this is humid north Texas In about 100 degree weather in summer.

Thanks alot for the imput. I am not worried at all because both days I rode it was pretty cool. The raptor maintinance file says 202` I think.

 

The sensor that turns the fan on is on the bottom of the radiator. Raptors come with a 160 degree tstat so they got to run pretty hard before the radiator reaches 195 to close the sensor.
