- Drain coolant and oil -- Drain the cooling system and engine oil to prevent spills.
- Remove intake and exhaust manifolds -- Disconnect and remove both manifolds from the cylinder head.
- Remove timing belt -- Remove the timing belt following manufacturer procedure.
- Remove rocker arms and camshaft -- Remove rocker arms and camshaft from the old head (if applicable).
- Remove cylinder head bolts -- Loosen and remove the cylinder head bolts in the correct sequence (typically reverse of tightening sequence).
- Remove old cylinder head -- Carefully lift the old cylinder head off the engine block; note gasket orientation. Be careful that foreign material does not fall into coolant and oil passage ways.
- Clean block deck -- Thoroughly clean the engine block deck surface; remove all old gasket material and debris. Check deck for flatness.
- Prepare new cylinder head -- Clean the new cylinder head mating surface; ensure all oil and coolant passages are clear.
- Install new head gasket -- Position the new head gasket on the block deck; ensure correct orientation.
- Install new cylinder head -- Carefully position the new assembled cylinder head onto the block; align dowel pins.
- Install new head bolts -- Use new TTY (torque-to-yield) head bolts -- never reuse old bolts. Apply thread lubricant as specified.
- Torque in sequence -- Tighten head bolts in the correct sequence in two or three stages: Step 1: 29 Nm (21 ft-lbs), then Step 2: turn 120 ° (for throttle body models) or Step 2: 72 Nm (53 ft-lbs) then Step 3: 118 Nm (87 ft-lbs) -- follow your specific engine model's specification.
- Reinstall timing components -- Reinstall timing belt, camshaft sprockets, and tensioners; align timing marks.
- Reinstall rocker arms and camshaft -- Refit rocker arms and camshaft; set rocker clearances by the installer after assembly.

- Refill fluids -- Fill with correct engine oil and coolant mixture (50/50 antifreeze/water).
- Bleed cooling system -- Start engine and bleed air from the cooling system per manufacturer procedure.
- Check for leaks -- Inspect for oil or coolant leaks around the cylinder head area.
- Road test -- Test drive to verify proper engine performance, no overheating, and no unusual noises.
- Casting Inspection: High-strength aluminum alloy casting checked for porosity, cracks, or defects using low-pressure die casting for uniform density.
- Dimensional Inspection: Combustion chamber volume, valve seat geometry, and deck flatness verified within OEM tolerances.
- Valve-to-Seat Sealing Test: Each cylinder head pressure tested and vacuum tested to guarantee zero leaks.
- Valve Seat Hardening: Valve seats are induction hardened to withstand higher combustion temperatures of turbo diesel applications.
