Volvo Penta D3 impeller pump – 21379102

Volvo Penta D3 impeller pump 21379102 is an original seawater pump (also known as an impeller pump or external water pump) essential for the cooling system of various Volvo Penta D3-series diesel engines. This pump draws in seawater and pumps it through the heat exchanger, ensuring the engine stays at an optimal operating temperature and preventing overheating. This part replaces older part numbers such as 21106041. Without a properly functioning impeller pump, water circulation may decrease, leading to higher engine temperatures and potential engine damage.

Key features and benefits:

Reliable cooling water circulation: Ensures seawater continuously flows through the cooling system.
Original Volvo Penta part: OEM quality for a perfect fit and long-lasting performance.
Direct replacement: Suitable for replacing older part numbers like 21106041.
Prevents overheating: Keeps the engine at the right temperature under varying loads.
