I got a 2004 sportsman 500 and my fan comes on properly when the bike heats up but it won't shut off until I turn my bike off for a while, any suggestions? Thermostat?

Might need a new temp sensor, radiator cleaning or change of coolant - if the coolant is over 3 years old, it should be changed and powersports coolant installed - don't use automotive coolant unless it is a low or no silicate formula

Coolant is brand new and rad has been cleaned but it sat for like 3 years caked full of mud but everything seems to be running fine other than the fan not shutting off
