Examination
1. Raise the vehicle and place it on stands, then place a stand under the engine oil pan. Place a large board between the sump and stand and carefully lift the engine to relieve the supports. Do not place a board under the drain plug of the pan.
2. Check for support (indicated by arrows) cracks, hardening or delamination from the metal substrate.
3. Check if the support plates move relative to the engine or frame (to do this, shake the supports with a mount, or a large screwdriver). If movement is felt, lower the engine and tighten the mounts.
4. To slow down aging, lubricate the rubber parts of the supports with a preservative.
Replacement
1. Disconnect the battery from the mass, raise the car and place it on stands.
2. Turn away nuts and bolts, raise the engine and remove a support.
3. Installation is carried out in the reverse order. Lubricate threads of nuts and bolts with locking compound and tighten securely.
