Oil overheat warning light

I have a 2002 Foreman 450 ES Recently the oil overheat light keeps coming on. My friend had a similar atv and was told it was the sensor for the fan and not to worry about it. His motor went out. I am wondering if it could be the oil cooler or oil pump causing this and how to check for which one it would be?

Yeah, it would be best if you had a manual. Make sure your fan is kicking on when it is hot enough. If it's not, I would check the thermal sensor, first. The manual is probably going to tell you to take it out and submerse it in hot motor oil at a certain temperature, while you check the resistance with an ohmmeter. Might be easier just to replace it with a new one, though. If that checks good, I would check the fan, itself.

I've never seen that problem with a Foreman, unless you are just overworking it and getting it hot, but usually you can let them cool down and they are fine. I have seen the fan quit working on a lot of the 350 Ranchers and it will melt the piston and rings. It seems to be a common problem with them.
