Yamaha - Water Inlet Cover Cooling System Component 6L2-45214-00-00. Overview. The water inlet area is one of those spots that takes a beating over time-debris, sand, and constant water flow all add up. When the cover gets worn or damaged, it can affect how water feeds into the cooling system. I've seen engines run hotter than they should just because this part wasn't sealing or sitting right. It's a simple replacement, but it plays a big role in keeping things running cool and steady.. Key Features.
