FAQ

Q1: Is this cylinder head a complete assembly ready to install?
A: Yes, this is a complete bare cylinder head assembly. It comes with valve guides and seats pre-installed. However, you will need to transfer the valves, springs, retainers, and camshaft from your old head unless you purchase those components separately.

Q2: How can I verify this head fits my specific Mitsubishi 4M50 engine?
A: The most reliable method is to check the casting number on your old cylinder head. It should match the OEM number ME202621 or ME202621-6. Additionally, measure the head gasket size and cylinder bore diameter to confirm it matches the 4M50 specification.

Q3: What maintenance is recommended after installing a new cylinder head?
A: After installation, follow the factory torque sequence and tightening specifications for the head bolts. It is critical to retorque the head bolts after the engine has been run and reached operating temperature for the first time. Also, ensure the cooling system is flushed and filled with the correct coolant mixture to prevent hot spots and thermal stress on the new head.
