FAQ

Q1: Is this cylinder head a direct bolt-on replacement for my Mitsubishi 6D22 engine?
A: Yes, this cylinder head (ME999969) is a direct-fit, aftermarket replacement. It comes fully machined with valve guides and seats installed. Ensure your engine block surface is clean and flat before installation. Reuse your original head bolts or replace with new ones as per the engine service manual.

Q2: Can I use this cylinder head on both the 6D22 and 6D22T engines?
A: Yes, this part is compatible with both naturally aspirated (6D22) and turbocharged (6D22T) versions of the engine. The core casting is identical, though we recommend checking the valve seat hardness for turbo applications to ensure optimal longevity under higher thermal loads.

Q3: What is the recommended installation procedure for this cylinder head?
A: We recommend following the official Mitsubishi 6D22 service manual. Key steps include: 1) Clean the engine block surface thoroughly. 2) Apply a thin layer of lubricant to the head bolt threads and under the bolt heads. 3) Tighten the head bolts in the correct sequence and to the specified torque in multiple steps (e.g., 120 Nm, then 180 Nm, then a 90-degree turn). 4) After initial run-in, re-torque the head bolts as specified by the manufacturer.
