The marine engine coolant expansion tank holds expanding coolant and lets air separate from the system. It is used on marine propulsion and auxiliary engines on workboats, supply vessels, tugs and barges.
The cooling system keeps engine temperature under control by moving coolant, raw water and air through the block, head, oil cooler and radiator or heat exchanger.
Why it matters
Overheating is one of the fastest ways to damage pistons, liners, gaskets and bearings, so worn cooling parts should be replaced before they fail.
Common signs it needs replacing
- Low coolant level or coolant in the oil
- Coolant leaks or white residue around joints
- Poor cooling at full load in hot weather
- Noisy bearings or wobbling pulleys
How to order the right part
- Share the engine make, model and serial number from the engine nameplate.
- Send a clear photo of the old part and any numbers cast or stamped on it.
- Tell us the application (for example generator set, compressor, pump or vessel) and running hours.
- Ask about available options, condition (new or reconditioned) and lead time.
