Cover(S), Cylinder Head: Removal: Right
WARNING: This page is about a different variant/trim than selected.
NOTE:
The magnetic timing wheels must not come in contact with magnets (pickup tools, trays, ect.) or any other strong magnetic field. This will destroy the timing wheels ability to correctly relay camshaft position to the camshaft position sensor.
- Disconnect and isolate the negative battery cable.
- Remove the upper intake manifold. Refer to MANIFOLD, INTAKE, REMOVAL .
- Cover the open intake ports to prevent debris from entering the engine.
- Remove the bolt (1) securing the oil level indicator tube to the upper intake manifold support bracket and position the oil level indicator tube aside.
- Remove the Exhaust Gas Recirculation (EGR) cooler and position aside. Refer to COOLER, EXHAUST GAS RECIRCULATION (EGR), REMOVAL
.NOTE:
It is not necessary to drain the cooling system or remove the cooling hoses from the EGR cooler.
- Remove the upper intake manifold support bracket to cylinder head bolt (1) and remove the bracket.
- Disconnect the wire harness connectors (1 and 2) from the variable valve timing solenoids on the right cylinder head cover.NOTE:
Mark the variable valve timing solenoid connectors with a paint pen or equivalent so that they may be reinstalled in their original locations.
- Disengage the wire harness retainers from the right cylinder head cover.
- Mark the variable valve timing solenoids (1 and 2) with a paint pen or equivalent so that they may be reinstalled in their original locations.
- Remove the variable valve timing solenoids. Refer to SOLENOID, VARIABLE VALVE TIMING, REMOVAL
.
- Disconnect the Variable Valve Lift (VVL) solenoid wire harness connector (1).
- Disconnect the wire harness connector (1) from the right side Camshaft Position (CMP) sensor.
- Disconnect the injector (1) and ignition (2) wire harness retainers and position the wire harness aside.
- Disconnect the wire harness retainer (2) from the rear of the cylinder head cover and position the wire harness (1) aside.
- Remove the right side ignition coils and fasteners (1). Refer to 3.6L
- Remove the camshaft position sensor and fastener (1). Refer to 3.6L
- Remove the VVL solenoid (1) from the right cylinder head cover
.
- Remove the PCV valve. Refer to VALVE, POSITIVE CRANKCASE VENTILATION (PCV), REMOVAL
- Loosen the cylinder head cover mounting bolts (1) and remove the cylinder head cover.
- Remove and discard the cylinder head cover gasket (1).
- The spark plug tube seals (2) can be reused if not damaged.CAUTION:
Do not use oil based liquids, wire brushes, abrasive wheels or metal scrapers to clean the engine gasket surfaces. Use only isopropyl (rubbing) alcohol, along with plastic or wooden scrapers. Improper gasket surface preparation may result in engine fluid leakage.
- Remove all residual sealant from the cylinder head, timing chain cover and cylinder head cover mating surfaces. Refer to ENGINE GASKET SURFACE PREPARATION .
