My buddy's '07 overheated last season. After riding for four hours we stopped for a cocktail. When we started up again it overheated and pooped out the coolant within 5 minutes of startup. When we got it trailered back to the cabin we pulled the thermostat and verified it was working. Once again when it would overheat it would crap out the coolant so we refilled and burped the air out of it. Then it would overheat again. The sled ran like a top for the past several seasons without any engine/coolant issues or associated maintenance actions. I swagged we had a bad water pump so we pulled the engine. The impeller and shaft look fine. Y'all have any ideas on where to look? I'm at a loss.
Another clue - the radiator stayed cool.

have you flushed the coolers and the rad out? might have a chunk of crap from a hose coming apart internally restricting the flow. have had it happen in air and hydraulic systems at work.

So heat exchangers are not getting warm? Did you crack the rear bleeder screw?

Depending on where it's leaking coolant at, it could be the coolant tank instead of the cap based off of this thread:

Not sure about the front exchanger or running boards, but the radiator stayed cool.

rad is after the right side cooler on my sleds, so i would say the coolers are staying cold.

Have a look at my thread. Sounds similar. Wound up being the head gasket.

RS Venture GT losing coolant
Related to RS Venture GT takes forever to warm up, now I find myself losing coolant. To recap, it had low coolant with no obvious leak, replaced the thermostat, refilled and it idles fine and gets up to temp and pressure. I also installed a temp gauge and bled the system of air (had it...
