Really need some help!!!!!!! Over heating

doornenbal · Jan 14, 2010

A 2004 Summit 800 that has a can and scratchers we have changed thermostats, temp sensor, checked the rave valves, can see no pintched line any place on the sled. Not leaking out at all. Any ideas we don`t think it is the water pump because the rear cooler warms up

please help not sure what direction to go and dealers are out of options

over heat

delete the thermostat
at any time did someone disconnect the coolin hoses and possibly stuff a papertowel in hose or end of cooler to keep from leaking out?
water pump inlet ect ect.
would sirculate very poorly.
you said rear cooler gets warm not hot,do both sides of cooler get warm?
disch and suction

Does the front cooler get hot? has it been going through coolant?

Does it always overheat or just in marginal snow?

Blown head gasket?

Coolant level doesn't change, so I would say no. Pull the T-stat out of the housing and let it flow that way. Sounds like you're getting marginal coolant flow.

track tension set correct, bogey and axel bearings in good shape
Hyfax good , no mouse nest in the exhaust , air lock in the cooler (good chance of this) along with all the other things
