About 5502003201 - Seawater Pump
Published catalog details are identification references. They do not establish current stock, supplied condition, or confirmed fitment for your engine.
5502003201 is a seawater pump catalogued for MTU 396 engines. The catalog unit weight is 26.620 kg, which we use to estimate freight before quoting.
Technical Notes: Cooling system
The cooling system removes heat from the cylinder liners, cylinder heads, lube oil, and charge air. Marine MTU engines usually combine an engine coolant circuit with a seawater circuit through heat exchangers, while generator engines often use radiators. Coolant quality has a direct effect on liner cavitation and pump seal life.
When This Type of Part Is Usually Replaced
- coolant leaks from the pump weep hole indicate seal wear
- engine temperature rises under load or fluctuates, pointing to thermostats or flow problems
- seawater pump impellers show cracked or missing vanes at inspection
Checks Before Ordering
- Replace thermostats and their seals together, and check the opening temperature on the replacement
- Seawater pump impellers should be kept as onboard spares for marine engines
- Flush and refill with an approved coolant after replacing pumps or heat-exchanger parts
