i have a 03 raptor, the problem is that i have only seen the fan run a hand full of times.. now, since the motor has been built, im overheating.. how can i check to see if the fan works and what can i do to check my over heating problem?? i just changed oil, not milking. all of the coolant in the overflow tank shoots out. not much in the radiator is gone?? please help!!!! thankx

 

You will need a Metal Thermometer that goes up to arund 220..
You will need a Cooking pot
You will need a Propain tourch (or somthing like that)
You will need water..

Ok Take your fan sencer out of the bottom of the radiator...Put the metal part of the sincer in the water in the pan..Place your metal thermometer in the water too..Heat bottom of pan SLOWLY...{Do not heat up sincer fast it will not work right anymore} Ok watch your thermometer while you are heating the bottom of pan slowly..Your fan sould kick on around 202 to 205...You can test up to around 230 but i would not go any higher..If it was working right it would have came on before 210...

This is the easyest way i have found to test your cooling fan..Just dont put open flame on sincer..

I hope this helps..[img]i/expressions/face-icon-small-smile.gif[/img]

 

wowoow i did that and mine did not kick in until 218..

 

I think a rappy fan kicks on at 202 but i would have to look back in the book...The Thermometer your putting in the water to see how hot its getting can be off..Im sure the old one i use is off a little..But its a good way to find out if your fan is kicking on or not

 

The thermostatic switch lasts less than 2 years. I am on my third one. Just go buy another one.

 

thanks guys for all the help!!!!!!! i will try these tings and post back.. once again thanks alot
