The initial steps are to relieve the fuel system pressure and disconnect the battery. Drain the cooling system and remove the drivebelt. Take out the PCV and EVAP system components, as well as the cowl.

When installing head bolts, applying clean engine oil to M10 bolt threads and hardened washers (if equipped), with the chamfered side of the washers facing the bolt heads, is recommended. For M8 head bolts, thread sealant should be applied to the bolt threads.

To remove the cylinder head, you need to take off several components including the timing chain, oil control valves, timing chain tensioner, chain guides, camshafts, rocker arms, and lash adjusters.

Before starting, disconnect the batteries' negative terminals and drain the coolant.

Complete the remaining installation steps in reverse order. Finally, add coolant, change the engine oil and filter, and start the engine to check for proper operation and leaks.

The cylinder head, with the camshaft in place and the exhaust manifold attached, should be carefully lifted off the engine block, and any external components should be removed for thorough cleaning and inspection.

After removing the cylinder head, it should be inspected and serviced as necessary. Any damage should be addressed during this phase.

Disconnect the exhaust pipe from the turbocharger, remove the viscous fan and drive assembly, and raise the engine with support or a hoist. Remove the right engine mount through-bolt and the engine mount itself. Disconnect the turbo oil drain fitting and seal the openings. Disconnect the air intake temperature sensor wiring, remove the air filter housing and snorkel, and tape the open turbo port. Disconnect heater hoses, oil supply line, and coolant lines from the turbocharger, sealing the openings. Remove the EGR cooler, exhaust manifold with the turbo attached, fan and shroud assembly, and the drive belt. Lower the alternator, disconnect the upper radiator hose, and label and disconnect all wiring attached to the cylinder head. Remove the engine oil dipstick tube bolt, air intake housing, pump-to-fuel rail line, fuel rail-to-head lines, and fuel line shield. Remove the fuel injectors and rocker housing.
