What should be done if engine mounts are broken or deteriorated in six cylinder engine on 2005 Chevrolet Trailblazer?

Engine mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately to prevent damage to driveline components. During the check, the engine must be raised slightly to remove the weight from the mounts. Begin by raising the vehicle and securely supporting it on jackstands, then position a jack under the engine oil pan with a large block of wood between the jack head and the oil pan, carefully raising the engine just enough to relieve the weight from the mounts without fully supporting the engine. Inspect the mounts for any cracks, hardened rubber, or separation from the metal plates, noting that rubber may split down the center. Applying rubber preservative or WD-40 can help slow deterioration. Check for any relative movement between the mount plates and the engine or frame using a large screwdriver or pry bar; if movement is detected, first check the tightness of the mount fasteners before concluding that the mounts are faulty, as broken mounts typically allow noticeable engine movement when pried or under load. To replace the mounts, disconnect the cable from the negative terminal of the battery, remove the cooling fan, disconnect the MAP sensor, and remove the upper attaching nuts of both left and right engine mounts for easier access. Raise the vehicle again and support it securely, then place a block of wood on a floor jack positioned under the oil pan, and remove the lower attaching nut(s). If equipped, remove the oil pan shield at this time, lower the vehicle, and raise the engine just enough to clear the unbolted mounts from their brackets before removing them. Installation follows the reverse order of removal, using non-hardening thread locking compound on the mount fasteners and ensuring they are tightened to the specified torque.
