Lexus 12361-31171 Insulator, Engine Mounting, Front(For Transverse Engine)

To inspect the engine mounts, lift the vehicle onto jack stands and place a jack under the engine oil pan. Also, raise the engine slightly to check the mounts for cracked or hardened rubber, or movement between the mount plates and engine. For replacement, remove the mount-to-engine bracket nut from the other mount. Install the new mount with a non-hardening thread locking compound on the bolts and nuts.

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.
