REMOVAL & INSTALLATION




CAUTION
If any repair operation requires the removal of a component of the air conditioning system (on vehicles so equipped), do not disconnect the refrigerant lines. If it is impossible to move the component out of the way with the lines attached, have the air conditioning system evacuated by a trained service professional. The air conditioning system contains refrigerant under pressure. This gas can be very dangerous. 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. 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.

  60.  

To install:
  1. Assemble the clutch disc and pressure plate to the flywheel for manual transaxle vehicles.
  2.  
  3. Install the transaxle.
  4.  
  5. Lift the engine into position and lower it into the car, aligning the mounts and bushings.
  6.  

When installing the engine mounts and vibration dampers in the following steps, the bolts running through the large rubber bushings should only be set snug or finger-tight until all are in place. They must be tightened to the correct tension in the correct order if they are to dampen vibration properly.

  1. Install the through-bolt for the left engine mount. Install the two smaller bolts, tightening them to 33 ft. lbs. (45 Nm).
  2.  
  3. Install the nut on the front motor mount, tightening it to 14 ft. lbs. (20 Nm). Install the three bolts holding the rear engine mount bracket to the engine. Tighten them to 28 ft. lbs. (39 Nm). Tighten the nut to 14 ft. lbs. (20 Nm).
  4.  
  5. Install the anti-torque rod at the rear of the engine. Make certain the washers are correctly placed.
  6.  
  7. Install the center beam under the engine. Check that the rubber damper on the beam is centered in its mount on the transmission. If not centered, loosen the bolts for the beam and/or damper and adjust as needed. Tighten the beam retaining bolts to 37 ft. lbs. (50 Nm) and the damper bolts to 40 ft. lbs. (55 Nm).
  8.  
  9. At this point the engine is loosely mounted in the vehicle. Slacken the hoist chains, allowing the engine to settle into place. The vehicle must be sitting level during the next step.
  10.  
  11. With the vehicle sitting level, tighten the mounting bolts/nuts in the order given to the proper torque. Both the order and tightness are important; the bushings play a great role in damping engine vibration.
