Parts:
SW524 Cooling Fan Switch ...AutoZone ...$32.99
Spal 4" 12v Pull Cooling Fan...EBay........$35.99
12v 2 prong male/female connector ...RadioShack....$5.99
Shrink Wrap ...RadioShack..$3.49
ATC Splash Proof Fuse Holder..AutoZone..$3.29
and about a 4' peice of wire i had laying around , i went a little extra and added some 1/4" split loom wire wrap , i got that at Shucks/O'Rielly Auto ..$6.99
So for roughly $88.74 i got a cooling fan that turns on when the temp gets too hot at about 195 then shuts off by itself at about 180
On the Thermo Switch , just go to AutoZone and give them that SW524 part number and they should be able to find it , i think its for a Mitsubishi car , i just cant remember its been too long

Here is my setup , i got the fan from EBay (its the same fan KTM uses) its a Spal Pull Fan http://www.ebay.com/itm/ws/eBayISAPI.dl ... 0932579727 , it needs to be a pull fan not a push fan as it needs to PULL air thru the radiators , the switch is off a car , its a fairly straight forward install , also i would highly recommend getting a 1.6 or 1.8 radiator cap , and Engine Ice instead of coolant , it alone will drop your engine temps by 50 degree's here is a basic jetting guideline to go by for Main Jet
Sea level 165
2000 ft.. 162
4000 ft.. 160
6000 ft.. 158
8000 ft.. 155
The benefit is no worry about overheating and being stranded with no coolant or worse a blown head gasket 30 miles from your rig/camp
I have the same problem with my CRF. Just going to 3-5 miles the engine becomes so hot and the heat comes and touches to my feet. Don't make out what need to do?Hi all, hoping some one can help with an overheating problem I have with my CRF 450X 2010. I've had this bike quite a while and never had a single issue with it. On my last 2 rides the bike overheated and dumped a lot of coolant out of it. The first time was at the top of a difficult hill - enduro and the second time when i was doing a lot of waiting at idle riding with my daughter. I assumed after the second time i had a cooling system issue . After doing a bit of online research everyone who has a problem like this heads for jetting or exhaust changes, not one person even mentioned the cooling system ! I found this odd but it did get me thinking , I noticed after the last ride before the heating issue that i had damage to the header pipe where it bends around the engine. It must have coped a hit and it was slightly kinked directly after it leaves the engine . I'm not sure when i did this and did not notice a performance change. Maybe just a coincidence but it is the only thing different about the bike. The bike is completely stock, I love it the way it is! has anyone had this problem ? Can anyone help me ?
