  25. Remove the service cover (A).
  26. Remove the bolts securing the transaxle support bracket (A).

    Tightening torque: 88.3 ~ 108 N·m

  27. Remove the engine and transaxle assembly by lifting the vehicle.
    • Before removing the engine and transaxle assembly, make sure that all hoses and wiring connectors are disconnected.
    • When removing the engine and transaxle, be careful not to damage surrounding parts or body components.

Installation

Installation is performed in the reverse order of removal. Perform the following:
  • Adjust the shift cable.
  • Adjust the throttle cable.
  • Fill the engine with engine oil.
  • Fill the transmission with fluid.
  • Fill the radiator and the coolant reservoir with engine coolant.
  • Set the heater control lever to the "HOT" position.
  • Bleed air from the cooling system.
  • (Refer to Cooling System - "Engine Coolant")
  • Clean the battery terminals and cable terminals with sandpaper, reconnect them, then apply grease to prevent corrosion.
  • Inspect for fuel leaks.
  • After assembling the fuel line, turn the ignition switch ON (do not operate the starter) so that the fuel pump operates for about two seconds and pressurizes the fuel line.
  • Repeat this procedure two or three times, then check all fuel line connections for leaks.
