Hi, I bought an 09 rzr 800 this fall and every time I take it out for a ride If the motor is up to temp and I sit at idle for any amount of time it starts flashing engine hot but once I start moving again it will cool back down not noticing any coolant use or loss. Could it be a thermostat issue I have read that they had a problem but wasn’t real sure exactly what to do. Note I have bled the system multiple times over and over and the radiator is clean and fan does work. Any info would be great thanks!
