Cylinder head, servicing

CAUTION!
When doing any repair work, especially in the engine compartment, pay attention to the following due to the confined conditions:
^ Route all the various lines (e.g. for fuel, hydraulic system, EVAP system, coolant, refrigerant, brake, vacuum) and electrical wiring so that the original positions are restored.
^ Ensure that there is sufficient clearance to all moving or hot components.

Note:
^ When installing an exchange cylinder head with installed camshaft, the contact surfaces between the hydraulic lifters and the cam must be oiled before installing the cylinder head cover.
^ The plastic packing pieces for protecting the open valves must not be removed until immediately before installing the cylinder head.
^ If the cylinder head is replaced, all the coolant in the system must also be replaced.
