REPAIR PROCEDURE

  1. Remove the intake manifold cover.
  2. Disconnect the intake air temperature (IAT) sensor connector, remove the breather hose, then remove the air cleaner housing.

INTAKE AIR TEMPERATURE (IAT) SENSOR

 

  1. Raise the vehicle on a lift.
  2. Loosen the rear engine mounting bolt two or three complete turns.

REAR ENGINE MOUNTING BOLT

 

  1. Loosen the front engine mount bolt about 4 mm.

FRONT ENGINE MOUNTING BOLT

 

  1. Lower the vehicle.
  2. Place a jack with a block of wood under the engine. Loosen the transmission mounting bracket bolt and nuts about 4 mm.

TRANSMISSION MOUNTING BRACKET

 

  1. While supporting the engine with a jack (making sure the engine is up against the mount), replace the side engine mount and its three mounting bolts.

SIDE ENGINE MOUNT ASSEMBLY

 

  1. Move the engine (not the bracket) in the directions of the arrows to center the bolt and nut in the oversized bolt holes of the side engine mounting bracket. Torque the bolt and the nut to 54 N.m (40 lb-ft).

NOTE: Two people may be needed, one to move the engine, and the other to observe the alignment and tighten the fasteners.

SIDE ENGINE MOUNTING BRACKET

 

  1. With the jack still under the engine, place a pry bar against the transmission mounting bracket, and move the bracket in the direction of the arrow until the oversized hole is covered by the centered bolt and nut, then torque the bolt to 54 N.m (40 lb-ft).

TRANSMISSION MOUNTING BRACKET

 

  1. Remove the jack, then raise the vehicle on the lift.
  2. Check for a gap of 4 mm (± 2 mm) between the metal tab of the engine mount bracket and the engine mount rubber bumper. Repeat step 10 if the clearance is not within the parameters.

ENGINE MOUNT BRACKET

 

  1. Tighten the rear mounting bolt.

REAR ENGINE MOUNTING BOLT

 

  1. Tighten the front mounting bolt.

FRONT ENGINE MOUNTING BOLT

 

  1. Lower the vehicle.
  2. Reinstall the air cleaner housing and the breather hose, then reconnect the IAT sensor connector.

INTAKE AIR TEMPERATURE (IAT) SENSOR CONNECTOR
