Description:
PP-Model MD7 Volvo Penta Heat Exchanger
This Seakamp Heat Exchanger is a marine-grade replacement designed for Volvo Penta marine petrol and diesel engines in sterndrive, inboard and IPS installations, most commonly fitted to the MD6A, MD7A family.
This unit forms the core of the engine's closed-circuit cooling system, transferring heat from the engine's fresh-water coolant loop to the raw-water (seawater) circuit. Engine coolant flows through the internal tube bundle while seawater circulates around the outer shell, efficiently carrying heat away before the coolant is recirculated through the engine.
Effective coolant temperature control is critical for stable engine operation under load. A correctly functioning heat exchanger helps prevent overheating, protects cylinder heads, liners and gaskets, and supports consistent power output and long service life in demanding marine environments.
Manufactured to match OEM dimensions, port orientation and mounting geometry, the Model MD7 is a true direct-fit replacement for the original Volvo Penta component. It installs without modification to existing hoses, brackets or pipework, making it suitable for planned maintenance, corrosion replacement or preventative servicing.
