Browse the complete MTU Series 4000 Marine Engine Parts range.
MTU 12V 4000 Engine Overview
The MTU 12V 4000 is a 12-cylinder, four-stroke, V-configuration diesel engine platform developed in multiple marine versions.
Different M-designations represent different engine versions, generations and applications. Fuel-system components, turbochargers, pumps, cooling-system parts, electronic components and internal engine parts should therefore be identified against the specific engine.
A request for simply “MTU 12V 4000 parts” may not contain enough information to identify a configuration-dependent component.
Whenever possible, provide:
- Complete engine model
- Engine serial number
- Existing part number
- Part description
- Quantity required
- Photographs of the component when available
- Delivery destination
