Cylinder Head Covers - Removal and Installation

REMOVAL
PROCEDURE

1. Disconnect the negative battery cable.

If the vehicle's audio system is equipped with an anti-theft code, make sure you have the correct code to reactivate the system before disconnecting the battery.
2. Disconnect the high-tension wires from the spark plugs, remove the support brackets and move them aside. Disconnect the wiring from the oil temperature sensor located on top of the rear cylinder head cover, near the timing belt.
3. Remove the upper intake manifold (refer to Intake Manifold - Removal and Installation).
4. At the left side of the rear cover, disconnect the PCV hose and remove the bolt securing the power steering hose bracket. Move the hose aside.
5. Disconnect the breather hose from the left side of the rear cylinder head cover. Move the hose aside.

6. Remove the mounting bolts and remove the cylinder head cover. If the cover is stuck, carefully tap it with a hammer through a wooden block.

Never attempt to separate the cover by prying on the mating surface. Any damage to the mating surface may cause leaks.
7. Remove the old gasket and sealing washers, then thoroughly clean the mating surfaces of the cylinder head and cover. Check the PCV valve for proper condition (refer to the Routine Maintenance chapter) and install it in its original location on the cover.

INSTALLATION
PROCEDURE

1. Place a new gasket in its groove and install the sealing washers on the mounting bolts.
2. Install the cover on the cylinder head, install the mounting bolts and tighten them in three stages to the specified torque.

Before installation, lightly lubricate the sealing washers and the contact areas of the cover and cylinder head with a soap solution.
3. Install the remaining components in the reverse order of removal.
