About X54920200040/87 - High-Temperature Water Pump
Published catalog details are identification references. They do not establish current stock, supplied condition, or confirmed fitment for your engine.
Keep the /87 suffix when requesting X54920200040/87. The catalog separates this high-temperature circuit pump from other cooling-pump references and lists EX54920200040/87 as a later number. The EX prefix alone does not confirm supply condition or a core-return policy.
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
Technical Data Status
Published catalog details help identify this part, but they are not a controlled drawing for the item offered. Measurements that are not shown here still need confirmation before substitution or order.
- Confirm high-temperature circuit, pump drive, ports, mounting interface, offered condition, and any exchange/core terms.
