Features & Advantages
OE Quality: Manufactured to Isuzu dimensional and material specifiions for perfect sealing and long service life.
MLS Construction: Multi-layer steel design provides superior resistance to combustion pressures and thermal cycling.
Precision Sealing Beads: Embossed beads around combustion chambers, coolant, and oil passages ensure positive sealing.
Heat-Activated Coating: Elastomer coating (Viton) flows into minor surface imperfections when heated, enhancing seal reliability.
Corrosion Resistant: Steel layers are coated to resist corrosion from coolant and combustion byproducts.
Restores Engine Performance: Eliminates compression loss, coolant consumption, overheating, and oil contamination.
Direct Replacement: Matches OE bore size, bolt holes, and port loions – no modifiion required.
Cost-Effective: Affordable alternative to genuine OEM without compromising reliability.

Installation Notes
Installation steps (overview for 4HG1 engine):
Drain coolant and engine oil – remove radiator hoses, thermostat.
Remove intake/exhaust manifolds, valve cover, timing components – as needed.
Remove cylinder head bolts – in reverse order of tightening sequence.
Lift cylinder head – inspect for cracks or damage.
Clean block deck and cylinder head surface – remove old gasket material. Do not scratch surfaces.
Check flatness – use straight edge and feeler gauge. Resurface if necessary (≤0.05mm over 150mm).
Chase cylinder head bolt holes – ensure clean, undamaged threads.
Install new gasket – position with correct orientation (look for “FRONT” or “TOP” marks). Do not use sealant unless specified.
Install cylinder head – carefully lower onto gasket. Do not shift once in contact.
Install new cylinder head bolts (recommended) – lubrie threads and underheads with engine oil.
Torque bolts in sequence – follow manufacturer specifiion (e.g., step 1: 50 Nm, step 2: 90 Nm, step 3: +90° +90°).
Reinstall all components – manifolds, timing, valve train, etc.
Refill coolant and oil – use proper fluids.
Start engine – check for leaks, air in cooling system, and abnormal noise.
Re-check after heat cycle – inspect for leaks.
Quality Control
Material Verifiion: Steel type and coating composition tested to meet OE specifiions.
Dimensional Inspection: Bore diameter, bolt hole loions, thickness, and shape verified against OE blueprints.
Sealing Bead Profile: Measured using laser profilometer to ensure consistent bead geometry.
Compression Test: Sample gaskets compressed to specified load to verify thickness recovery and coating adhesion.
Leak Test: Sample gaskets tested on a fixture with pressure to confirm no cross-leakage.
Visual Inspection: 100% checked for coating defects, scratches, or damaged beads.
Packaged Safely: Gasket sealed in plastic bag, boxed flat to prevent bending or creasing.
