FAQ

Q: How can I confirm this cylinder head fits my specific engine?
A: The most reliable method is to check the casting number on your old cylinder head. Look for the numbers “4915267” or “3802169” cast into the side or end of the head. If these match, this is the correct part for your NTA855 engine. You can also provide your engine serial number (ESN) for us to verify.

Q: Is this a complete cylinder head assembly or a bare head?
A: This is a bare cylinder head. It does not include valves, springs, retainers, or camshafts. You will need to transfer these components from your old head or purchase a new valvetrain kit separately. We recommend using new valve guides and seals during installation.

Q: What is the recommended installation procedure?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Thoroughly cleaning the engine block surface. 2) Using a new, OEM-spec head gasket. 3) Applying correct thread lubricant to head bolts. 4) Torquing the head bolts in the exact sequence and to the specific torque values provided in the NTA855 service manual. Improper torquing can lead to gasket failure or cylinder head damage.
