REMOVAL & INSTALLATION
The 4-cylinder engines utilize a timing gear cover.
- Remove the engine drive belts.
- Remove the right front inner fender splash shield.
- Remove the center bolt from the crankshaft pulley and slide the hub from the shaft.
- Remove the alternator lower bracket.
- Remove the front engine mounts.
- Using a floor jack, raise the engine.
- Remove the engine mount mounting bracket-to-cylinder block bolts. Remove the bracket and mount as an assembly.
- Remove the oil pan-to-front cover bolts.
- Remove the front cover-to-block bolts.
- Pull the cover slightly forward, just enough to allow cutting of the oil pan front seal flush with the block on both sides.
- Remove the front cover and attached portion of the oil pan seal.
- Clean the gasket surfaces thoroughly.
- Cut the tabs from the new oil pan front seal.
- Install the seal on the front cover, pressing the tips onto the holes provided.
- Coat the new gasket with sealer and position it on the front cover.
- Apply a 1 / 8 in. bead of silicone sealer to the joint formed at the oil pan and block.
- Align the front cover seal with a centering tool and install the front cover. Tighten the cover with the centering tool installed, then remove the tool.
- Install the front mount bracket assembly and lower alternator bracket. Lower the engine. Install the mount-to-engine cradle nuts.
- Coat the front cover oil seal contact area on the hub with clean engine oil. Position the hub on the crankshaft and slide it on until it bottoms against the crankshaft gear. Install the hub retaining bolt and tighten to 160 ft. lbs. (212 Nm). Install the belts and adjust their tension. Install the fender shield.
The V6 engine utilizes a timing chain cover.
- Remove the water pump. The procedure for this is given later in this section.
- If the car has air conditioning, remove the compressor from its brackets and move it aside. Do not disconnect any of the hoses.
- Remove the torsional damper as follows: remove the negative battery cable at the battery, remove the engine drive belts, raise the car, remove the right inner fender splash shield, remove the drive pulley, then remove the damper retaining bolt. Install a puller onto the damper and remove the damper.
The outer ring (weight) of the torsional damper is bonded to the hub with rubber. The balancer must be removed with a puller which acts on the inner hub only. Pulling on the outer portion of the balancer will break the rubber bond or destroy the tuning of the damper.
- Remove the front cover retaining bolts and remove the cover.
- Clean the front cover mating surfaces of all old sealer. Apply a 3 / 32 inch bead of silicone sealer to the front cover sealing surface.
- Place the front cover on the engine, install the water pump, then install the retaining bolts and tighten the small bolts to 6-9 ft. lbs., the medium size bolts to 13-18 ft. lbs., and the large bolts to 20-30 ft. lbs. (8-12, 18-24, and 27-41 Nm, respectively).
- Connect the lower radiator hose.
- Install the torsional damper as follows: coat the front cover seal contact area on the damper with clean engine oil. Place the damper on the crankshaft with the keyway aligned. Install the damper using a press which acts on the inner ring of the hub only. The press should thread into the crankshaft with at least 1 / 4 inch of thread engagement.
- Install the pulley onto the hub, and install both the pulley and the hub bolts. Tighten the pulley bolts to 20-30 ft. lbs. (27-41 Nm) and the hub (damper) bolt to 66-84 ft. lbs. (90-115 Nm).
- Install the inner fender splash shield. Install the drive belts and adjust their tension. Install the air conditioning compressor, if removed, and its drive belt; adjust the tension. Connect the negative battery cable. Fill the cooling system as outlined in .
TIMING COVER OIL SEAL
The oil seal on both engines can be replaced with the cover either on or off the engine. If the cover is on the engine, remove the crankshaft pulley and hub first. Remove the seal using a large prytool, being careful not to distort the seal mating surface. Install the new seal so that the open or helical side is towards the engine. Press it into place with a seal driver made for the purpose. Install the hub if removed.
