GENERAL DESCRIPTION

Inertia principal axes system is incorporated into the engine mount system.

  1. Longitudinal installation type of cylindrical liquid-filled engine front mounting bracket is used for reduction of idle vibration and improvement of ride feeling.
  2. For transaxle mounting body side bracket, liquid-filled mount is used to improve ride feeling by optimizing insulator.
  3. Upper installation of roll stopper bracket reduces engine rolling, and increase of insulator bore also reduces idle vibration.

REMOVAL AND INSTALLATION

CAUTIONBefore removing the steering wheel and air bag module assembly, always refer to AIR BAG SAFETY PRECAUTIONS , DRIVER-SIDE AIR BAG MODULE & CLOCKSPRING . Also, set the front wheels so that they are facing straight forward, and remove the ignition key. If you fail to do this, the SRS clock spring will be damaged, causing the SRS air bag to be inoperative and serious injury. * 1 : indicates parts which should be initially tightened, and then fully tightened after placing the vehicle horizontally and loading the full weight of the engine on the vehicle body. * 2 : Indicates parts which should be temporarily tightened, and then fully tightened with the vehicle on the ground in the unladen condition.
