Lexus 12362-31040 Insulator, Engine Mounting, RH(For Transverse Engine)

Engine mounts are usually very reliable and usually do not need intervention; however, if they are broken or worn, they should be replaced to avoid straining or damaging driveline elements. During the check the engine should be lifted slightly off the mounts to take the weight off them. First, lift the vehicle and firmly set it on jackstands; place a jack beneath the engine oil pan and insert a large wood block between the jack top and the oil pan; then lift the engine sufficiently off its mounts to shift the load off the mounts but remain far off the drain plug area. This is more important when only supporting a particular part of the body with a jack while the rest of it is under the engine. Test for deterioration at or around the mount area by examining the mounts for crack, hard rubber and if the mounts have totally come off from the metal plates; test the relative movement between the mount plates and the engine or frame with a large screw driver or a pry bar. If any movement is observed, drop the engine and compact the mount fasteners. For replacement, the vehicle should be on jackstands and the engine should also be supported. To deinstall, uninstall the bolts, lift the engine sideways, and disconnect the mount though an engine lift or floor jack and a wooden block placed under the oil pan can be used. If only a single mount is being replaced, the other mount's nut for the mount to engine bracket should be loosened to permit enough elevation of the engine for mount removal. It is done in the reverse method as the removal, applying non-hardening thread locking compound on the mount bolts and nuts while tightening it.

Engine Mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately to prevent damage or wear on driveline components. During the check, the engine or transaxle must be raised slightly to remove the weight from the mounts. Raise the vehicle and support it securely on jackstands, then remove the splash shields under the engine and position a jack under the engine oil pan, using a large block of wood between the jack and the oil pan to carefully raise the engine just enough to take the weight off the mounts, avoiding positioning the wood block under the oil drain plug. Inspect the mounts for cracked, hardened rubber or separation from the bushing in the center, and check for relative movement between the mount plates and the engine or frame, using a large screwdriver or pry bar to attempt to move the mounts; if movement is noted, lower the engine and tighten the mount fasteners. Apply rubber preservative to the mounts to slow deterioration. Disconnect the cable from the negative battery terminal, then raise the vehicle and support it securely on jackstands if not already done, and support the engine. If several mounts need replacement, only replace one at a time and tighten them as you go. For the passenger's side engine mount, remove the nuts securing the mount to the upper and lower brackets, then remove the bolts securing the mount to the frame and raise the transaxle enough to allow removal of the mount, ensuring to loosen the mounting nuts on the other engine mounts at the subframe for clearance. Installation is the reverse of removal, using thread-locking compound on the bolts and tightening them securely. For the driver's side transaxle mount, remove the nut securing the mount to the upper and lower brackets, then remove the bolts securing the mount to the frame and raise the engine enough for removal, again ensuring to loosen the mounting nuts on the other engine mounts for clearance. Installation follows the same reverse process with thread-locking compound. For the front engine mount, remove the fastener securing the mount to the bracket, then remove the bolts securing the mount to the frame and raise the engine enough for removal, with installation being the reverse and using thread-locking compound. For the rear engine mount, remove the mount nut and slide the through bolt out of the insulator, then remove the bolts securing the mount to the frame and raise the engine enough for removal, with installation being the reverse and using thread-locking compound. Finally, in the engine compartment, remove the bolts securing the engine movement control rod and its bracket, with installation being the reverse and using thread-locking compound on the bolts.

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.

When checking the mounts, you should inspect for cracked, hardened, or separated rubber, as well as any relative movement between the mount plates and the engine or frame.
