Description

he PCM R024002 is a genuine OEM pump-to-thermostat housing elbow used in Pleasurecraft Marine (PCM) fresh water cooling (FWC) systems.

This component connects the circulating water pump to the thermostat housing, forming a critical junction in the engine’s cooling circuit. It directs coolant flow from the pump into the thermostat assembly, ensuring proper circulation through the heat exchanger and engine block.

Unlike thermostats themselves, this is a hard component (housing/elbow), not a temperature-regulating part. Its role is structural and flow-directing—maintaining proper hose routing, sealing, and coolant transfer within the closed cooling system.

Constructed from marine-grade materials and machined to OEM tolerances, it is designed to withstand constant exposure to coolant, vibration, and thermal cycling typical in marine engines.

Parts Desk Insight

This part often gets overlooked—if you’re chasing a coolant leak around the thermostat housing, the elbow itself can corrode or crack, not just the gasket
