3. Drain the coolant. Remove the radiator.
When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are
quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove
fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless
it is contaminated or several years old.
4. Remove the A/C compressor and the power steering bracket, if so equipped, and position them out of
the way. DO NOT disconnect the A/C refrigerant lines.
5. Remove the alternator, drive belt(s) and, if equipped, the Thermactor pump.
6. Remove the fan.
7. Remove the water pump and the heater and radiator hoses.
8. Remove the drive pulley from the crankshaft.
9. Remove the front cover retaining bolts. If necessary, tap the cover lightly with a plastic hammer to
break the gasket seal. 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.
10. If the front cover oil seal needs replacement use the following procedure:
1. Support the front cover to prevent damage while driving out the seal.

3. Support the front cover to prevent damage while installing the seal.
4. Coat the new front cover oil seal with Lubriplate® or equivalent. Install the new seal in the
front cover.

with the chamfered end toward the front cover, if removed. Position the gasket and the front cover
plate on the cylinder block. Temporarily install the four front cover screws to position the gasket and
cover plate in plate. Install and tighten the two cover plate attaching bolts, then remove the four
screws that were temporarily installed.
