Sierra Sea Water Pump 18-36001, Replaces 46-862914A13, Fits V6 & V8 Engines with V-Belt and 1 Piece Pump

The Sierra Sea Water Pump 18-36001 is a complete sea water pump assembly built to circulate raw cooling water through V6 & V8 engines equipped with a v-belt and 1 piece pump design. As the sea water pump is the component that draws in raw water and pushes it through the engine's cooling passages, a worn or failing unit is a common cause of overheating, so replacing the full assembly with 18-36001 restores reliable raw water flow rather than patching an aging pump housing. This pump uses impeller 18-3016-1, so buyers who already have this pump installed and only need the wear component should order that impeller separately rather than the full assembly. The housing and internal components are constructed from glass material for durability in a raw water cooling environment. This pump directly replaces OEM number 46-862914A13, making it a straightforward swap for boat owners and marine technicians servicing V6 and V8 engines with the v-belt, 1 piece pump configuration. Each unit ships as a single complete sea water pump, ready to install in place of the original equipment part.
