Product Description
Restore the cooling performance of your Volvo Penta diesel engine with this high-quality intercooler housing, Volvo Penta OEM 861657.

Replacing a worn intercooler housing helps restore proper cooling performance.
Why does the Volvo Penta intercooler housing fail?

Why should I replace a corroded intercooler housing?
A damaged or corroded intercooler housing can reduce cooling efficiency, increase intake air temperatures and negatively affect engine performance. Replacing it helps maintain reliable operation and protects the engine from long-term damage.
Is this suitable for both freshwater and saltwater boats?
Yes. The housing is manufactured from marine-grade materials suitable for both freshwater and saltwater applications. Regular inspection and maintenance are still recommended, especially in saltwater environments.
