PP-129670-33000 Yanmar Oil Cooler Assembly
The PP-129670-33000 Yanmar Oil Cooler Assembly is a compact marine grade lube oil cooler designed for use on Yanmar JH series marine diesel engines, including the widely installed 3JH and 4JH platforms used in cruising yachts and light commercial vessels.

This oil cooler plays a key role in regulating engine oil temperature, ensuring correct oil viscosity and stable lubrication across a wide range of operating loads and ambient conditions. By controlling oil temperature, it helps protect bearings, pistons, camshafts, and valve train components from thermal stress and premature wear.

The 129670-33000 uses a shell and tube heat exchanger design, where engine oil flows through an internal core while raw water circulates around the exterior shell. Heat is efficiently transferred away from the oil and discharged via the seawater circuit, maintaining optimal lubrication performance.

Manufactured to OEM dimensional and flow specifications, this unit is a direct fit replacement requiring no modification to original hoses, fittings, or mounting hardware. It is commonly replaced during major servicing intervals or when corrosion, internal blockage, or zinc depletion reduces cooling efficiency in marine environments.

Used extensively across both mechanical and electronically controlled JH series engines, the 129670-33000 oil cooler is a proven, reliable component
