REMOVAL & INSTALLATION
See Figures 1 and 2
- Disconnect the negative battery cable.
- Remove the oil pan, as described earlier in this section.
- Drain the cooling system and remove the radiator, as described in this section.
- Remove the air conditioning compressor and power steering bracket, if equipped.
- Remove the alternator, thermactor pump and drive belt(s).
- Remove the cooling fan.
- Remove the water pump, heater hoses and radiator hoses.
- Remove the crankshaft pulley, as described earlier in this section.
- Remove the front cover retaining bolts. If necessary, tap the cover lightly with a plastic mallet to break the gasket seal, then remove the front cover. If the front cover plate gasket needs replacement, remove the two screws and remove the plate. If necessary, remove the guide sleeves from the cylinder block.
- Clean the front cover mating surfaces of all gasket material and/or sealer. If the front cover seal is being replaced, support the cover to prevent damage and drive out the seal using tool T74P-6700-A or equivalent. Coat the new seal with heavy SG or SH engine oil and install it in the cover, making sure it is not cocked.
- Install the timing gears, if removed, making sure the timing marks are correctly aligned. Tighten the camshaft gear bolt to 30-36 ft. lbs. (41-49 Nm).
- Apply sealing compound to the gasket surfaces on the cylinder block and back side of the front cover plate. Install the guide sleeves with new seal rings lubricated with engine oil to prevent cutting the rings, with the chamfered end toward the front cover. Position the gasket and front cover plate on the cylinder block. Temporarily install four front cover screws to position the gasket and front cover plate in place. Install and tighten two cover plate attaching bolts, then remove the four screws that were temporarily installed.
- Apply sealing compound to the front cover gasket surface, then place the gasket in position on the front cover.
- Place the front cover on the engine and start all retaining screws two or three turns. Center the cover by inserting an alignment tool (T74P-6019-A or equivalent) in the oil seal.
- Tighten the front cover attaching screws to 13-16 ft. lbs. (17-21 Nm).
- Install the crankshaft pulley and tighten the center bolt to 85-96 ft. lbs. (115-130 Nm).
- Install the oil pan, as described earlier in this section.
- Install the water pump, heater hose, air conditioning compressor, alternator, thermactor pump and drive belt(s). Adjust the belt tension. For more details on the correct drive belt tensioning procedure, refer to Routine Maintenance .
- Install the radiator.
- Connect the negative battery cable.
When the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the Powertrain Control Module (PCM) relearns its adaptive strategy. The vehicle may need to be driven about 10 miles (16 km) or more to relearn the strategy.
- Fill and bleed the cooling system, then operate the engine at fast idle and check for leaks.
