Yamaha - Water Pump Gasket - Cooling System Seal - 6EE-G4315-00-00

Overview

Anytime I’m into a water pump, I don’t reuse old gaskets—just not worth the risk. A bad seal here can throw off the whole cooling system, even if everything else is new. I’ve seen engines overheat just from a small leak at the pump housing. With a fresh gasket in place, you know the system is sealed up and ready to move water the way it should.
