Cooling system problem

>what part I should check into
how about the temperature sensor?

Do they tend to be off several degrees when they go bad? Like 35 for example and still trip consistently just not at the right temp? If so then I will definitely start there. Thanks for replying to my thread btw

There is a sensor on the radiator. Check that. By the way, at what temp does it open?

It opens at 235 according to the mechanical gauge I put in and shuts off at about 210 the over heat light never comes on either I'm not sure what temp trips that but it's probably close to 240

Is it even possible for the sensor to come that far out of spec? I didn't know if they can require maintenance to stay in calibration or if when they crap out they just stop working altogether and some other sensor could be telling my fan to kick on that late like a secondary switch?

Thing is, you usually have two sensors. One is the sensor on the engine that gives you a reading on the dashboard. One is located on the radiator and it acts like a thermo switch and starts your radiator fan. That can be broken due to heat and being old and can open later than it should. I would check owner manual or some repair manual for your atv since i know from the bikes i own that the sensor usually opens at around 230 ish degrees for some models. So, check manual to see the value when the sensor should open or just replace it with a sensor that opens at a lower temp value so you have peace of mind.

Sounds easy enough. Thanks for the help anon!

If u want to check ur sensor, take it off, suspend it in some oil and heat the oil. Taake a multimeter set on ohms and check reading between pins. When it opens you shoukd read 0 ohms or 0.04-0.09 depending on multimeter. Then check oil temp. If value is bigger than what you find in the manual, then replace sensor. Hope it helps.

Or just buy a new sensor and see if it fixes the problem. Much easier.

Yeah man for sure. Best way to fix any piece of machinery is always to just blast the ol parts cannon at it until the problem goes away or your wallet is empty. Doing actual diagnostics and tests is for fags!
