MITSUBISHI L400 Bus 1995.05-2000.05 2.0 16V (85KW,115PS) Cylinder Head Assy MD305479 4G63 8V I-MIEV Pajero Montero Sport Towny – OEM MD305479

Product Overview: Supplied as a complete assembly, this cylinder head directly replaces the original on 4G63 engines used across Mitsubishi models. It restores compression, valve timing and coolant sealing to original specification for workshop repair and overhaul work, and is new and pressure tested before dispatch. It is intended for replace/repair use and is a cost-effective alternative to reconditioning a damaged original head. The unit is inspected for flatness and gallery cleanliness prior to dispatch, ensuring it is ready for immediate fitment.

Key Features: Produced from high-grade aluminium alloy or cast iron and finished on modern CNC equipment, the head reproduces original deck height, valve seat angles and port dimensions. Factory-fitted valve guides and seats reduce installation time, while matched chamber volumes promote even compression and smooth combustion. Reinforced ribs around the injector or plug bosses add resistance to thermal fatigue, and the ground cam carrier ensures stable camshaft support. All internal oil and coolant galleries are cleaned, inspected and flow-checked before the head is assembled and tested. The casting is dimensionally stable and accepts original-specification gaskets, bolts and ancillary components.

Vehicle Compatibility: This cylinder head suits MITSUBISHI L400 Bus 1995.05-2000.05; MITSUBISHI DELICA / SPACE GEAR 1995.09-2002.10. Where a vehicle family was built with more than one engine, check the engine code and original part numbers before ordering. Coverage spans the 1994-2002, 1990-2006, 2006-, 1982-2004 model years.

Specifications: Engine code / family: 4G63; Material: high-grade aluminium alloy or cast iron; Size: STD; Condition: New, supplied for replace/repair use; Warranty: 12 Months; Packaging: neutral export carton.

OEM / Reference Numbers: OEM and cross-reference numbers: MD305479. Use these with the engine code and vehicle details to verify fitment, since superseded and market-specific numbers can differ.

Applications: Serving Mitsubishi vehicles in passenger car, van and light truck roles, this assembly suits repair garages, engine rebuilders, fleet workshops and restoration projects. Common uses include head gasket failure repair, valve and seat replacement, overheating damage rectification and complete engine overhaul.

Benefits / Replacement Information: Choosing a complete, tested assembly over a reconditioned original reduces turnaround time and removes uncertainty about hidden cracks or previously machined surfaces. Once installed it restores compression, valve sealing and coolant integrity, resolving overheating, misfire and coolant consumption symptoms.

Installation or Fitment Notes: Correct fitment depends on a clean block deck, sound threads and a flat head surface. Always use the gasket and fastener specification listed for the engine, renewing stretch bolts as required, and tighten strictly in sequence. Refill with the correct coolant, bleed the system and check for leaks after the first warm-up.
