3801578 — Water Pump 3801578 20726077 For Volvo Penta Tad520Ge Tad720Ge Tad721Ge Tad722Ge Engine

This is a water pump, responsible for circulating coolant through the engine block and radiator to maintain optimal operating temperature. Manufactured to meet strict OEM specifications, it ensures efficient heat transfer and prevents engine overheating, unlike a worn pump with a failing impeller or seal. Operators may observe engine overheating, steam from the engine bay, or coolant leaks under the equipment if the water pump is compromised.

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

Visible coolant leaks from the front of the engine or a whining noise from the pump pulley are early indicators of a failing water pump. If left unaddressed, the engine will begin to overheat, potentially leading to severe internal damage and costly repairs. Continued operation with an overheating engine risks catastrophic component failure.

Installation Tip

Thoroughly clean the mounting surface on the engine block to ensure a proper seal for the new pump. Do not reuse the old gasket or sealant; always use a new one designed for the application.

Service Note

Inspect the drive belt tensioner and the condition of the radiator and heater hoses when replacing the water pump.
