Removal
All vehicles
1. Recover the refrigerant. For additional information, refer to Heating and Air Conditioning.
Vehicles with auxiliary heat
2. Drain the cooling system. For additional information, refer to Cooling System.
3. Disconnect the 2 auxiliary heat coolant hoses.
4. Disconnect the coolant hose from the intake manifold and position the coolant hose assembly aside.
All Vehicles
5. Disconnect the quick connect couplings and remove the crankcase vent tube. For additional information, refer to Fuel Delivery and Air Induction.
6. Remove the nut and the ground cable and disconnect the wiring harness retainer.
7. Disconnect the PCM electrical connector.
8. Disconnect the 2 electrical connectors and the wiring harness retainer.
9. Disconnect the evaporator outlet and inlet fittings.
^ Discard the O-ring seals.
10. Disconnect the RH radio ignition interference capacitor and engine cooling fan clutch electrical connectors.
11. Remove the RH ignition coils. For additional information, refer to Ignition System.
12. Disconnect the RH variable camshaft timing (VCT) solenoid electrical connector.
13. Disconnect the RH camshaft position (CMP) sensor electrical connector.
14. Disconnect the 2 engine wiring harness retainers from the RH valve cover studs.
15. CAUTION: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges which make leak paths. Use a plastic scraping tool to remove all traces of old sealant.
CAUTION: When removing the valve cover, make sure to avoid damaging the variable camshaft timing (VCT) solenoid.
NOTE: The fasteners are part of the valve cover and should not be removed.
Fully loosen the fasteners and remove the RH valve cover and gasket.
^ Clean the valve cover mating surface of the cylinder head with silicone gasket remover and metal surface prep. Follow the directions on the packaging.
^ Discard the valve cover gasket. Clean the valve cover gasket groove with soap and water or a suitable solvent.
Installation
All vehicles
1. NOTE: If the valve cover is not secured within 4 minutes, the sealant must be removed and the sealing area cleaned with metal surface prep and silicone gasket remover. Follow the directions on the packaging. Allow to dry until there is no sign of wetness, or 4 minutes, whichever is longer. Failure to follow this procedure can cause future oil leakage.
Apply a bead of silicone gasket and sealant in 2 places where the engine front cover meets the cylinder head.
2. CAUTION: When installing the valve cover, make sure to avoid damaging the variable camshaft timing (VCT) solenoid.
Position the LH valve cover and new gasket on the cylinder head and tighten the fasteners in the sequence shown.
^ Tighten to 10 Nm (89 lb-in).
3. Install the RH ignition coils.
4. Using new O-ring seals, connect the evaporator outlet and inlet fittings.
^ Lubricate the O-ring seals with PAG oil prior to installation.
5. Connect the 2 electrical connectors and the wiring harness retainer.
6. Connect the PCM electrical connector.
7. Connect the wiring harness retainer and ground cable and install the nut.
^ Tighten to 10 Nm (89 lb-in).
8. Connect the RH radio ignition interference capacitor and engine cooling fan clutch electrical connectors.
9. Connect the RH VCT solenoid electrical connector.
10. Connect the wiring harness retainers to the valve cover.
11. Position the crankcase vent tube and connect the quick connect couplings.
Vehicles with auxiliary heat
12. Position the coolant hose assembly and connect the coolant hose to the intake manifold.
13. Connect the 2 auxiliary heat coolant hoses.
14. Fill and bleed the coolant system.
All vehicles
15. Evacuate, leak test and charge the refrigerant system. For additional information, refer to Heating and Air Conditioning.
