⚠️ Important — Verify Before Ordering
- Engine Model Confirmation: This cylinder block fits 4HK1, 4HF1, 4HG1, and 4HE1 engine models. Bore dimensions and main bearing specifications may vary between engines. Verify the original engine model and block number before ordering.
- Bare Block vs. Assembly: This product may be a Bare Block or a Block Assembly. Confirm with the supplier whether internal components (crankshaft, pistons, connecting rods, etc.) are included.
- Machining Condition Confirmation: Some aftermarket blocks may be semi-finished (requires boring/honing) or finished (ready for assembly). Confirm bore machining condition and main bearing bore dimensions before ordering.
- Pre-Installation Verification: Please provide the VIN, engine number, or original block number for precise fitment confirmation.

⚠️ Important
The cylinder block is the core foundation component of the engine. Installation involves complete engine disassembly and precision assembly. Professional installation by a qualified technician in a workshop equipped for engine overhaul is strongly recommended. Thoroughly clean all oil galleries, water jackets, and threaded holes before installation. Metal debris or old sealant residue must not remain. After installation, tighten main bearing bolts and cylinder head bolts to the specified torque and sequence per the workshop manual.
- Block cleaning: Thoroughly clean the block, focusing on main oil galleries, water jackets, threaded holes, and the deck surface. Blow out oil galleries with compressed air.
- Install crankshaft: Install main bearing shells and tighten main bearing cap bolts to the specified torque and sequence (reference ISUZU 4H-Series workshop manual).
- Check crankshaft end play: Measure crankshaft end play with a dial indicator, confirming it is within specification.
- Install piston-connecting rod assemblies: Install piston-connecting rod assemblies into the cylinder bores and tighten connecting rod bolts to the specified torque.
- Install head gasket and cylinder head: Clean the block deck and cylinder head bottom surface, install a new head gasket, and tighten head bolts in diagonal sequence in steps.
- Install timing system: Install timing gears / chain / belt and align the timing marks.
- Install oil pan and accessories: Install the oil pan, oil pump, water pump, and other accessories; fill with engine oil and coolant.
- Pre-start check and road test: Manually rotate the crankshaft to confirm no interference. Start the engine and idle, check oil pressure, coolant temperature, and for abnormal noise. Perform a road test.
- Every 10,000 km or 12 months: Check oil level and quality; inspect the block exterior for oil or coolant seepage.
- Every 50,000 km: Check engine compression pressure and evaluate cylinder bore wear.
- When engine oil consumption, abnormal coolant temperature, abnormal noise, or severe power loss is detected: Perform a compression test and cylinder bore inspection promptly; overhaul or replace the block if necessary.
