Description

The water pump rotary seal is an essential sealing component of the cooling system in BRP Can-Am engines. The OEM part number 420650370 (also replaces part number 21040113901) ensures the water pump shaft is sealed, preventing any coolant leakage into the engine crankcase. This aftermarket replacement seal is recommended during a water pump overhaul, in case of coolant leakage, or as a preventive measure during a complete engine overhaul. Available in packs of 1, 5, or 20 units.

Why Replace the Water Pump Rotary Seal?

The water pump rotary seal is subjected to repeated thermal cycles and the pressure of the cooling system. Over time, it degrades and can leak coolant, compromising engine cooling efficiency and potentially leading to serious overheating.

Coolant leak at the water pump
Presence of coolant in the engine oil
Repeated engine overheating without apparent cause
Preventive water pump overhaul (recommended every 2 years or 200 hours)

It is highly recommended to replace the rotary seal every time the water pump is serviced. Ordering in packs of 5 or 20 units allows for spare parts for several seasons or multiple vehicles.
