3812519 — Rebuild Kit Of Water Pump 21212799 3812519 For Volvo Penta Engine 4.3 5.0 5.7

This is a rebuild kit for a water pump, containing all necessary seals, gaskets, and often an impeller to restore the pump's functionality. It is manufactured to precise dimensions, ensuring a leak-free seal and efficient coolant circulation, unlike a worn-out pump that can lead to overheating. Operators may notice the engine temperature gauge rising above normal, steam from the engine bay, or a loss of coolant if the water pump is failing.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of a failing water pump is often a coolant leak from the weep hole or a whining noise from the bearing. If ignored, the impeller can degrade further, leading to insufficient coolant circulation and engine overheating. Prolonged overheating can cause severe internal engine damage, including warped cylinder heads or blown head gaskets.

Installation Tip

Thoroughly clean the water pump housing and mating surfaces before installing new gaskets and seals. Ensure the new impeller is correctly oriented on the shaft.

Service Note

Inspect the engine's thermostat and radiator hoses for signs of wear or blockage when servicing the water pump.
