Parts 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.

Cooling Circuit and Assembly Boundaries

Engine coolant and seawater circuits require separate identification. Pump, actuator, housing and seal references do not imply a complete repair kit.

Coolant pump0002000001 X54920200040/87	Complete pump versus repair components	0002000001 is listed under MTU 183. Preserve /87 on X54920200040/87 and confirm the high-temperature circuit.
Thermal actuatorX52420300037 05132155	Actuator only; housing and seals requested separately	Housing drawing position, operating marking and mating seal; no complete temperature curve is established here.
Pump seal700429100000	Specified ring and material	Dimension convention, material, fluid and sealing position; a nominally equal ring is not automatically equivalent.

Request a Line-by-Line Quote

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.

Component Coverage

Use these focused topics to narrow the catalog before sending a part-number list. Final fitment is confirmed against the complete engine or component reference.

MTU Coolant Pumps

Engine coolant pumps, shafts, seals, housings, and related replacement components.

MTU Seawater Pumps and Impellers

Marine raw-water pump parts selected by engine model and cooling-system configuration.

MTU Thermostats

Thermostats and temperature-control parts for marine, generator, rail, and industrial installations.

Catalog Scope and Fitment Method

MTU Cooling System Components includes catalog references listed under MTU 183, MTU 4000, MTU 396, MTU 956, MTU 1163, MTU 2000, Verify by engine serial number. Engine-specific fitment remains subject to verification. We do not treat a part number as interchangeable until the engine serial number, installation position, and any superseded reference have been checked.

Part Numbers & Selection Checks

These numbers have part-specific identification checks. Catalog measurements, where shown, still require confirmation for the quoted item and engine.

Part No. Component Engine Series Check Before Quote

0002000001 Coolant Pump MTU 183 Confirm pump drive, mounting flange, ports, and whether the quotation includes the complete pump or a repair scope. X54920200040/87 High-Temperature Water Pump MTU 4000 Confirm high-temperature circuit, pump drive, ports, mounting interface, offered condition, and any exchange/core terms.

What We Verify Before Quoting

Exact part number and quantity

Engine model, rating, and serial number

Nameplate photo or old-part photo when the marking is unclear

Destination country, delivery deadline, and preferred shipping method

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.

Don't See Your Part Number Here? Just Ask.

This page lists the references indexed for mtu cooling system components — it is not the full MTU spare-parts range, and a missing number says nothing about availability. Send the complete part number with your engine model and serial number: we check the reference, trace supersessions, name the supply grade, and confirm stock before quoting. If a number cannot be verified, we say so instead of shipping a guess.
