FAQ

Q1: Is this a complete cylinder head ready for installation?
A: Yes, this is a fully assembled cylinder head. It comes with pre-installed valves, valve guides, and valve seats. However, we recommend transferring over your original engine’s components like the injectors, glow plugs, and rocker arm assembly to ensure proper fitment.

Q2: How do I ensure this cylinder head fits my specific engine?
A: Please verify your engine’s model number is Mitsubishi S3Q. Additionally, check the casting number on your old cylinder head. If it matches 31C01-01015 (or the cross-referenced numbers listed above), this part is a direct replacement.

Q3: What is the recommended procedure before installing a new cylinder head?
A: Always clean the engine block deck surface thoroughly. Use a new head gasket and new head bolts (torque-to-yield bolts are recommended). Follow the manufacturer’s specified torque sequence and tightening angles. It is also good practice to check the cylinder head for flatness with a straight edge before installation.
