About 5802040806 - Impeller
Published catalog details are identification references. They do not establish current stock, supplied condition, or confirmed fitment for your engine.
5802040806 is an impeller from the coolant pump group of MTU 956 engines. It is the later number for 5802040506, so lists quoting that number are normally supplied as 5802040806. The catalog unit weight is 2.377 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
