Timing Cover: Service and Repair

REMOVAL

(1) Disconnect the battery negative cable.
(2) Drain cooling system.
(3) Remove the serpentine belt.
(4) Remove water pump.
(5) Remove power steering pump.
(6) Remove vibration damper.
(7) Loosen oil pan bolts and remove the front bolt at each side.
(8) Remove the cover bolts.
(9) Remove chain case cover and gasket using extreme caution to avoid damaging oil pan gasket.
(10) From the inside of the cover tap the front crankshaft oil seal outward. Be careful not to damage the timing cover sealing surface.

INSTALLATION

(1) Be sure mating surfaces of chain case cover and cylinder block are clean and free from burrs.
(2) Using a new cover gasket, carefully install chain case cover to avoid damaging oil pan gasket. Use a small amount of Mopar Silicone Rubber Adhesive Sealant, or equivalent, at the joint between timing chain cover gasket and the oil pan gasket. Finger tighten the timing chain cover bolts at this time.

CAUTION: If chain cover is replaced for any reason, be sure the oil hole (passenger side of cover) is plugged.
