2001 Grizzly 600 Overheating problem
I am having an issue with my 01 grizzly over heating. The fan doesnt seem to kick on at all ever. Sometimes it does but very rarely and my oil temp light comes on. I replaced the oil and filter thinking maybe the oil level was low since its oil cooled but still no luck. Does anyone have an suggestions before I have to take it to a shop. I am not very good with atv mechanics but I can do some basic repairs. Any suggestions would be helpful. Thanks!

2001 Grizzly 600 Overheating problem
I have a 99' grizzly 600 and having the same problem. Oil change does not effect . I did a complete flush of the oil system. Also checked my cooler to make sure it was not plugged up and it wasn't. I next changed the thermo unit. The fan was still not coming on, unless I disconnected the thermo unit and short circuited the wiring. Those wires are run to the back of the 4 wheeler to some relays. After playing with those my fan started running but my Oil Temp light still comes on. Checking the temp with a temp gun my temp got up to 350F, Inlet to the cooler was 197F outlet was 167F. My next experiment is to try and change out the relay assys. Hopefully that will work. If not then I am dead on the dirt I guess.
I will try and post again if I find out. May be awhile so check back. I hope this helps you greg529.

Finally after 2 months I had a chance to start tracking down this problem. All I did was follow the 2 power wires that came from the fan and started disconnecting every wire connection I could find. The problem the whole time was massive amounts of dirt inside these connections. I wish there was a way to prevent this. I really dont want to electrical tape all the connections because it will make a sticky mess if I ever have to take something apart again.

i'm having the same same problem as you guys on my 99 grizzly. but i think i found the problem, the main wiring harness somehow got onto the exhaust and it melted 5 of the wires together. but my question is, how long does it take for the fan to usually kick on? i know the fan is capable of working cuz i hooked it straight to the battery. i was just wondering when it kicks on so that i know if its working or if i'll have to dig deeper into the wiring. any help is appreciated.
