9. Disconnect the fuel tube spring lock coupling.





10. Disconnect the heater hose.





11. Disconnect the A/C suction tube at the accumulator.





12. Disconnect and remove the A/C suction tube.





13. Remove the nut and separate the A/C tube from the condenser.





14. Disconnect the A/C tube at the evaporator.





15. Remove the A/C tube.
1. Disconnect the pin-type retainer.
2. Remove the A/C tube.





16. Disconnect the evaporative emissions (EVAP) return tube.





17. Disconnect the wiring harness from the valve cover stud bolt.





18. Remove the bolts and the RH valve cover.





19. 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.

Clean and inspect the sealing surfaces and inspect the valve cover gaskets. If necessary, install new gaskets. Make sure the gaskets are correctly seated on the valve cover.

Installation





1. NOTE: If the valve cover is not secured within four minutes, the sealant must be removed and the sealing area cleaned with metal surface cleaner. Allow to dry until there is no sign of wetness, or four minutes, whichever is longer. Failure to follow this procedure can cause future oil leakage.

Apply a bead of silicone gasket and sealant in two places where the engine front cover meets the cylinder head.





2. Install the RH valve cover and finger tighten the bolts.





3. Tighten the RH valve cover bolts in the sequence shown.
