Before working on the timing cover, unplug the battery's negative terminal and loosen the accessory
Drive Belt. Then, take the fan brackets away from the timing cover and remove the fan and hub plus the shroud. Should the vehicle have it, remove the A/C compressor and generator bracket assembly from the engine cylinder head and lay it aside. After that, undo all of the vibration damper bolts together with the bolts holding the
Oil Pan-to-timing case cover and the timing case cover-to-cylinder block cover. Open the timing case cover and remove the gasket together, then remove the
Crankshaft oil seal from the cover's front. Before installation, wipe the gasket surfaces found on the timing case cover, oil pan and cylinder block. Hold a new crankshaft oil seal in the timing case cover, open edge facing inward and fix it with the 6139 Seal Installation Tool. Apply the gasket to the cylinder block and sit the timing case cover over the oil pan gasket and the cylinder block. Put Timing Case Cover Alignment and Seal Installation Tool 6139 into the crankshaft opening in the cover, then mount the bolts for attaching the timing cover to both the cylinder block and oil pan. The 1/4 inch bolts between the cover and the block go in at 7 Nm (60 in. lbs.), the 5/16 inch bolts on the front need 22 Nm (192 in. lbs.) and tighten the bolts holding the oil pan to the cover at 9.5 Nm (84 in. lbs.). Once the cover alignment tool is removed, next place a thin layer of engine oil on the hub of the vibration damper seal, using Silicone Rubber Adhesive Sealant on the crankshaft keyway as you insert it into the key. Apply a thin layer of grease on the vibration damper, washer and bolt and attach them with the bolt tightened to 108 Nm (80 ft. lbs.). You should install the A/C compressor and generator bracket assembly before installing the engine fan and hub assembly with shroud. After that, put on the accessory drive belt and secure it to the required tightness and reconnect the negative cable to the battery.
