Mitsubishi 4G64 MD040520 4G64 Complete Cylinder Head 22100-32680 MD354214 – OEM 2210032680

Product Overview: This complete cylinder head assembly is engineered for Mitsubishi 4G64 2.4-litre four-cylinder petrol engines used in SUVs, pickups, vans and light commercial vehicles. It is delivered as a fully assembled unit with valves, guides and seats installed and is machined to original equipment tolerances, providing a direct replacement for a cracked, warped or valve-damaged original cylinder head.

Key Features: The casting is produced from high-grade material and CNC-machined to hold accurate deck flatness, correct valve seat concentricity and matched combustion chamber volume. Valve guides and seats are fitted and honed for even sealing and balanced compression, and the cam carrier surfaces are finished for correct bearing clearance. The eight-valve configuration and combustion chamber shape are reproduced precisely to maintain factory combustion characteristics, while machined intake and exhaust flanges ensure correct gasket sealing.

Vehicle Compatibility: This head suits Mitsubishi Pajero, Pajero Sport, Montero and related 4G64-powered models produced between 1982 and 2019, as well as Hyundai commercial derivatives using the same engine. Because the 4G64 was built in several revisions, always verify the engine code, casting number and OE reference against the original component before ordering.

Specifications: Engine code 4G64; displacement 2.4 litres; four cylinders; eight valves; material cast iron or aluminium; standard size; new condition; complete assembly; 12-month warranty; intended for replacement and repair.

OEM / Reference Numbers: 2210032680, together with the cross references MD099389, MD192299, MD305479, MD040520 and MD354214. Match these numbers against the casting identification on the original head to be certain of the correct part.

Applications: Suitable for four-wheel-drive SUVs, utility pickups, vans and light trucks, covering routine repairs, engine overhauls, rebuilds and fleet maintenance where a factory-specification head is needed.

Benefits / Replacement Information: Replacing a failed head with this assembly restores compression, eliminates coolant and combustion gas leakage, and resolves overheating caused by cracking or distortion. Supplying the head complete avoids the lead time and cost of individually reconditioning valves, guides and seats.

Installation or Fitment Notes: Installation must be carried out by a qualified technician. Inspect the block deck for flatness and clean all mating surfaces, fit a new head gasket and new head bolts where specified, and torque in the correct sequence. Replace timing and cooling components as required, verify valve clearances and cam timing, then run the engine to operating temperature and confirm there are no leaks before road testing.
