So be careful with 2021 Husky FE350s. It's got two seals back to back in there with just a circlip between them. Very, very easy to hit that second seal with the drill bit. To remove that inner seal you have to remove the whole side cover, and water pump bearing.

Jeff do the new impellers work as good as the aftermarket metal ones.?

[@slaverace1]

Hello James: The Checkpoint impellers slavensracing.com/shop/water-pump-impeller-ktmhusaberg-2-strokes-checkpoint/ definitely improve coolant flow but it you have overheating issues, fan kits slavensracing.com/shop/radiator-fan-kit-for-ktm-husaberg-husqvarna-by-trail-tech/ are the only cure.

I hope this isn’t to stupid of a question: What are the signs that the water pump seal could be failing?

Gear box oil that looks like chicken soup

Hello Steve: When the pump seal fails, the pressurized coolant migrates pass the seal and into the transmission fluid. When the coolant integrates with the transmission fluid, the fluid becomes milky looking.
