2011 pro RMK. Was having over heating issues so I found the thermostat had fallen apart, replaced that as well as new seals in the head. Now sled stays around 125 and under down the trail and just playing around but any kind of hard pull the coolant temp shoots up immediately and starts coming back down when I let off. Sled runs fine otherwise, wondering if possible water pump or any other ideas? Only running 5-7 psi.
