Hey there snowmobile fans my indy 500 keeps blowing coolant out and popping out the rad cap , wondering if its a bad thermostat ? but then I heard from somebody that this sled doesnt have a thermostat , I have also recently blown and replaced a head gasket, is there anything else I may need to check or any common problems
