The Active Control Engine Mount is a component that generates vibrations to cancel out engine vibration and reduce noise at idle. It operates using a Diverter Valve that utilizes engine vacuum to vibrate a diaphragm within the mount. This vibration is then transferred to a liquid inside the mount, which in turn transfers the vibration to the mount's rubber pad, effectively canceling out the engine vibration. To replace the VSV, the two vacuum hoses and the large hose connected to it must be disconnected and labeled for proper reassembly. The valve's mounting bolt and electrical connector are then removed, followed by the disconnection of the remaining hose. The installation process is the reverse of the removal steps.

It is crucial to replace broken or deteriorated engine mounts immediately to prevent damage or wear on the driveline components.

Installation is the reverse of the removal. Use thread-locking compound on the bolts and ensure they are tightened securely.

Check the mounts for any cracks, hardened rubber, or separation from the metal plates. Additionally, look for separation of the rubber from the bushing in the center of the mount.

On these models, disconnect the electrical connectors at the front engine mount before removing the mounting nuts.
