Request Parts InquiryParts by Engine Series
Cooling system parts vary by engine application — marine (raw-water or keel-cooled), industrial (radiator), or rail. We confirm the correct variant by engine model and serial number for MTU 2000, 4000, 396, 595, and 956 series.
MTU engine cooling systems are application-specific — a marine engine running on raw-water cooling through a keel cooler requires different pump and thermostat configurations than an industrial engine on a closed-loop radiator or a rail engine with split-circuit cooling. Ordering the wrong cooling-system variant is one of the most common parts-matching errors because the same engine series can have multiple cooling configurations.
Our cooling system catalog covers coolant pumps (5062000601, 5592001001/31), seawater pumps (5502003201), impellers (X00022524, 5582040406, 5592010007, 5592010307), thermostats (5841800175), coolant pump shafts (5552010005, 5842040714), flanges (8490740063), and sight glasses (5502030060). For each inquiry, we confirm the correct variant by engine model, serial number, and application type. Common replacement triggers include impeller wear from abrasive cooling water, pump shaft seal leakage, and thermostat sticking in the open or closed position.

Common RFQ Scenarios
- Bulk replenishment for repeated service items
- Cross-series part-number verification
- Old-stock replacement and supersession checks
- Mixed RFQ lists from service companies or shipyards
For mixed lists, send the spreadsheet as-is. We return line-by-line availability, replacement notes, and practical shipping options instead of a generic catalog reply.
