Toyota 12361-31120 Insulator, Engine Mounting, Front

Engine mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately to prevent added strain on driveline components that may cause damage or wear. During the check, the engine must be raised slightly to remove the weight from the mounts. Raise the vehicle and support it securely on jackstands, then position a jack under the engine oil pan with a large wood block between the jack head and the oil pan, carefully raising the engine just enough to take the weight off the mounts while avoiding the drain plug. Inspect the mounts for cracked, hardened rubber or separation from the metal plates, noting that the rubber may split down the center. Check for relative movement between the mount plates and the engine or frame using a large screwdriver or prybar to attempt to move the mounts; if movement is noted, lower the engine and tighten the mount fasteners. To replace a mount, disconnect the cable from the negative terminal of the battery, raise the vehicle, and support it securely on jackstands while supporting the engine. Remove the fasteners, raise the engine, and detach the mount, using an engine hoist or a floor jack with a wood block under the oil pan. Even if only one mount is being replaced, remove the mount-to-engine bracket nut from the other mount to allow sufficient height for removal. Installation is the reverse of removal, applying non-hardening thread locking compound on the mount bolts/nuts and ensuring they are tightened securely.

Applying rubber preservative can help slow deterioration.
