26. Disconnect the wiring harness.

  Note
  • Do not disconnect the engine side of this wiring harness.

27. Remove the A/C compressor with the pipes connected and secure the A/C compressor using wire or rope so that it is out of the way. (See A/C COMPRESSOR REMOVAL/INSTALLATION.)

28. Remove the engine and transaxle component using an engine jack in the order indicated in the figure.

29. Install in the reverse order of removal.

30. Start the engine and:

  (1) Inspect the runout and contact on the pulley and belt.

  (2) Inspect for engine oil, engine coolant, ATF, power steering fluid and fuel leakage.

  (3) Verify the ignition timing, idle speed and idle mixture. (See ENGINE TUNE-UP [MZI-3.7].)

  (4) Engine accessories operation

31. Perform a road test.

  Note
