Description:

PP-119574-44010 Yanmar Heat Exchanger / Fresh Water Cooler Assembly
The PP-119574-44010 Yanmar Heat Exchanger, also referred to as the fresh water cooler assembly, is a primary cooling component used on Yanmar 6LY and 6LY2 high output marine diesel engines operating with a closed circuit cooling system.

This unit is a 5" x 23" copper nickel (CuNi) shell and tube heat exchanger, designed to transfer heat from the engine’s internal freshwater (coolant) circuit to raw seawater. Coolant flows through the internal tube bundle while seawater circulates around it, maintaining stable operating temperatures under continuous load and high power conditions.

Copper nickel construction provides excellent resistance to corrosion, scaling, and electrolysis in harsh marine environments. Sacrificial zinc anodes are fitted to protect the core and are service replaceable as part of routine maintenance.

Manufactured to OEM dimensional and flow specifications, the 119574 44010 is a direct fit replacement requiring no modification to original mounting brackets, hose routing, or coolant plumbing. It is commonly replaced during major engine services or when internal blockage, zinc neglect, or seawater corrosion reduces cooling efficiency.

Used across both mechanical and electronically controlled 6LY / 6LY2 engine variants, this heat exchanger is a proven and widely supported solution.
