It may be necessary to remove additional components to perform this operation if you cannot cut the gasket cleanly as described in Step 10.

  1. Disconnect the negative battery cable from the battery, drain the cooling system, and remove the radiator together with the upper and lower radiator hoses.
  2.  


CAUTION
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.

  1. Loosen the alternator drive belt adjusting screw and remove the drive belt. Remove the bolts, which attach the alternator bracket to the engine and set the alternator aside out of the way.
  2.  
  3. Mark and remove the distributor. Refer to Distributor Removal and Installation, if necessary.
  4.  
  5. Remove the oil pump attaching screws, then take out the pump and its drive spindle.
  6.  
  7. Remove the cooling fan and the fan pulley together with the drive belt.
  8.  
  9. Remove the water pump.
  10.  
  11. Remove the crankshaft pulley bolt and remove the crankshaft pulley.
  12.  
  13. Remove the bolts holding the front cover to the front of the cylinder block, the four bolts which retain the front of the oil pan to the bottom of the front cover, and the two bolts which are screwed down through the front of the cylinder head and into the top of the front cover.
  14.  
  15. Carefully pry the front cover off the front of the engine.
  16.  
  17. Cut the exposed front section of the oil pan gasket away from the oil pan. Do the same to the gasket at the top of the front cover. Remove the two side gaskets and clean all of the mating surfaces.
  18.  
  19. Cut the portions needed from a new oil pan gasket and top front cover gasket.
  20.  
  21. Apply sealer to all of the gaskets and position them on the engine in their proper places.
  22.  
  23. Apply a light coating of grease to the crankshaft oil seal and carefully mount the front cover to the front of the engine and install all of the mounting bolts.
  24.  

Tighten the 8mm bolts to 7-12 ft. lbs. and the 6mm bolts to 36-72 inch lbs. Tighten the oil pan attaching bolts to 48-84 inch lbs.

  1. Before installing the oil pump, place the gasket over the shaft and make sure that the mark on the drive spindle faces (aligned) with the oil pump hole.
  2.  
  3. Install the oil pump after priming it with oil. For oil pump installation procedures, see Oil Pump Removal and Installation in this section.
  4.  
  5. Install the crankshaft pulley and bolt.
  6.  
  7. Install the water pump with a new gasket. Install the fan pulley and cooling fan. Install the drive belt and adjust the belt to the correct tension.
  8.  
  9. Install the distributor in the correct position. Reconnect the alternator bracket and alternator if it was removed. Install the drive belt and adjust the belt to the correct tension.
  10.  
  11. Reconnect the upper and lower radiator hoses and refill the cooling system.
  12.  
  13. Reconnect the negative battery cable. Start the engine, check ignition timing and check for leaks.
  14.

It may be necessary to remove additional components to perform this operation if you cannot cut the gasket cleanly as described in Step 18. This procedure requires the removal and subsequent installation of the fuel injection pump. It is a good idea to read through the Diesel Fuel Injection section in before you continue with this procedure. You may decide that the job is better left to a qualified service technician.

  1. Disconnect the negative battery cable. Drain the cooling system and then remove the radiator together with the upper and lower radiator hoses.
  2.  


CAUTION
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.

  1. Remove the fan, fan coupling and fan pulley.
  2.  
  3. Unscrew the retaining bolts on the crankshaft damper pulley. Use a plastic mallet and lightly tap around the outer edges of the pulley; this should loosen it enough so that you can pull it off. If not, use a two armed gear puller.
  4.  
  5. Remove the power steering pump, bracket and idler pulley (if so equipped).
  6.  
  7. Unscrew the five mounting bolts and remove the front dust cover.
  8.  
  9. Remove the thermostat housing and the bottom bypass inlet with the hose.
  10.  
  11. Remove the engine slinger.
  12.  
  13. Tag and disconnect all hoses and lines running from the injection pump. Make sure to plug any hoses or lines to prevent dust or dirt from entering.
  14.  
  15. Drain the engine oil.
  16.  


CAUTION
The EPA warns that prolonged contact with used engine oil may cause a number of skin disorders, including cancer! You should make every effort to minimize your exposure to used engine oil. Protective gloves should be worn when changing the oil. Wash your hands and any other exposed skin areas as soon as possible after exposure to used engine oil. Soap and water, or waterless hand cleaner should be used.

  1. Remove the oil cooler and coolant hose together with the oil filter.
