i have 2001 bombardier ds650 its got less than 25 hours on it. i went to start it today left it idling for about 10minutes and the red light comes on but the fan does not turn on so i turned on the fan manually with a paper clip and it runs like a new fan i also checked the fuse under the seat its good i dont now what else to do.

 

i just took apart the the thermostat housing everything looks ok i cleaned up the two sensors and put it back together and the fan still wont turn on

 

Pull your fan sensor and check it with an ohm meter.You need infinite,i believe.
Good luck.

 

I hate to tell you this, but your fan is no good. I know I went through 5 fans on my 2001 DS. Bombardier knows about the problem. They gave me the 5 fans because they knew it was a design flaw. To correct the problem the new DS went to rubber mounts on the fan.

In order to correct your problem you need to use rubber mounts. After I made rubber mounts for my DS I had no fan troubles.

Maybe I could draw you picture how I did it and e-mail it to you if you want.

 

the fan runs like new if i use a paper clip but it wont turn on when it gets hot

 

does anybody know were i can get the water temp sensor. i tried heating up the sensor with a lighter but it wont work

 

your local dealer ought to carry them.. i have had two of them go out on me... i think they are around 18 or 19 $...

 

The original fans were not waterproof.
Try spraying some WD into the rotor while hand spinning.
Let dry for an hour and then retest.

This is because the viberation has jared the brushes in the motor. You said it will run if you gave it a push. That means all the sensors are working, sending electricity to it.

 

i use the paper clip to unite the two conectors that go to the thermal fan sensor and i just turn the key and the fan turns on
