PCM Engine Cooling Hose Assembly | 97310

Keep your engines cooling circuit intact with this OEM-specification cooling hose assembly for PCM inboard engines. At this price point, this is a formed or molded hose shaped to follow a specific routing path in the engine compartment that a straight piece of bulk hose cannot replicate. Using the correct formed hose ensures proper fit, correct bend radius, and a reliable seal at both ends without stress on the hose wall.

Marine cooling hoses operate in a demanding environment: constant heat cycling, vibration, coolant chemical exposure, and the occasional contact with bilge water or oil. A hose that has softened, hardened, or developed a pinhole leak can cause rapid overheating replacing it on schedule or at the first sign of deterioration is far less costly than the engine damage that follows.

Best Use Case

Best suited for replacing a deteriorated, cracked, or leaking cooling hose in the PCM engine cooling circuit during scheduled maintenance or overheating diagnosis. Also the correct replacement when a hose inspection reveals softness, swelling, cracking at the ends, or visible weeping at a clamp. Formed hoses like this one should be replaced as a unit they cannot be repaired or substituted with straight hose stock cut to length.

Parts Desk Insights

Confirm fitment using your engine model and serial number before ordering formed cooling hoses are position-specific and will not fit correctly if ordered for the wrong engine or circuit location. When replacing this hose, inspect all clamps and the mating fittings for corrosion; a new hose on a corroded barb or a weak clamp is a leak waiting to happen. Replace clamps at the same time as a matter of course. For related cooling system fittings, see the PCM Engine Cooling Elbow 97387 and the PCM Pump-to-Thermostat Housing Elbow R024002.
