Oil temperature light comes on

Hey all. I'm riding an 03 Rincon and one of the problems that I have been having is that the oil temperature light turns on with in about 10 mins of riding it. The fan works and I have been thinking about replacing the Thermostat. Any ideas of what could be causing this?

Thank you

Have you cleaned out your radiator and oil cooler? Spray both sides of them down. Most say don't use a power washer, but I do with a tip that is designed for light cleaning. You can also test your thermostat by taking it out and boiling it with a thermometer in the water and see what temperature it opens at. You can use the search engine on this site to find out the temperature it is supposed to open at.

A common issue, however your 10 minute time may be incorrect....start it up, and time it (just leave her idle for 5 minutes. If it comes on at 5 minutes, the oil temp sender wire has most likely broken and fallen off. ECM time out, will turn on the lamp (no signal) Located about center bottom at the back of the motor, easily accessed by removing a rear tire. Re-attach the wire, yer done.

Pressure washer and rads are not friends Phil! The water pressure bends the light aluminum fins on the rad, which effects cooling. (No air can pass) hose water pressure, even when you jet it with your finger can damage the fins... Rad cleaning usually needs the front end to come off to do it properly.

Whatever in life be your goal, keep your eye upon the doughnut and not on the hole.

I had a large piece of wood come up off the trail and knock a hole in the plastic skid plate. In doing so it also knocked the wire off the rear of the engine and would cause the oil temp to come on. It was an easy fix once I found the wire off, I just crimped the connector and reinstalled it.
