FAQ

Q1: How do I confirm this cylinder liner fits my Isuzu engine?
Check your engine model number (4HK1 or 6HK1) and the existing part number on your old liner. This part number 8-94391602-1 is a direct OEM replacement for these engines. If your engine serial number falls within the standard production range, it should fit. For absolute certainty, provide your engine’s VIN or serial number to our support team for verification.

Q2: What is the recommended installation procedure?
Installation should be performed by a qualified mechanic. Ensure the cylinder block bore is clean and within spec. Apply a thin layer of engine oil to the liner’s outer surface before pressing it in. Use a suitable installation tool to avoid distortion. After installation, check the liner protrusion and bore diameter to ensure proper piston clearance.

Q3: How long does this cylinder liner typically last?
Service life depends on operating conditions, maintenance practices, and engine load. Under normal conditions, this liner can last 3,000–6,000 hours before requiring replacement. Regular oil changes, proper coolant maintenance, and avoiding overheating will significantly extend its lifespan. Inspect the liner for scoring or excessive wear during each engine overhaul.
