FAQ

Q1: How do I know if the DLLA156SN820 nozzle is compatible with my engine?
A: First, locate your current injector nozzle’s part number. It is usually stamped on the nozzle body. If it matches DLLA156SN820, 105015-8200, or 58200, it is a direct fit. If you are unsure, please provide your engine model (e.g., 4HK1, 6HK1) for verification.

Q2: What is the correct installation procedure for this nozzle?
A: Installation should be performed by a qualified technician. Key steps include: 1) Thoroughly clean the injector bore in the cylinder head. 2) Install a new copper gasket. 3) Tighten the injector to the manufacturer’s specified torque. 4) Use new high-pressure fuel lines. Improper installation can lead to leaks or engine damage.

Q3: How can I ensure a long service life from this fuel nozzle?
A: The lifespan of a fuel nozzle is highly dependent on fuel quality. Always use clean, high-quality diesel fuel and replace your fuel filters at recommended intervals. Contaminants in the fuel are the primary cause of nozzle wear and blockage.
