Inspection
2. Before inspection, you should unload the supports by slightly lifting the engine.
3. Raise the vehicle and support it vertically, then place a hydraulic jack under the engine pan. A block of wood must be placed between the jack lever and the pallet. Raise the engine slightly to relieve the mounts. Do not place the entire weight of the engine on the jack.
4. Check the supports for tears or separation of the rubber elements from the metal base. Sometimes the rubber elements delaminate right in the center. To reduce wear, it is recommended to apply silicone grease to the supports.
5. Evaluate the relative movement of the support plates and the engine or load-bearing element. Determine the movement by wedging the supports with a large screwdriver or pry bar. If there is excessive movement in the supports, first check that the fasteners are securely tightened. As a rule, if a support fails, this is manifested by significant movement of the engine when the support wedges or when a load is applied to the power unit.
Replacement
6. Disconnect the negative battery cable.
7. Remove the radiator fan (see chapter 3).
8. Disconnect the wire and remove the MAP sensor (absolute pressure).
9. Unscrew the upper connecting nuts of the left and right engine mount (even if only one support is supposed to be replaced) (see illustration).
17.9. To facilitate the replacement of one support, it is necessary to unscrew the upper connecting nuts of both supports
10. Raise the vehicle and install vertical supports.
11. Install a hydraulic jack under the engine pan. A block of wood must be placed between the jack lever and the pallet. Raise the engine slightly to relieve the mounts.
12. Unscrew the bottom (no) connecting (s) nut (And) supports.
13. If the design provides for a sump guard, remove it at this stage of the procedure.
14. Lower the vehicle.
15. Raise the engine with a jack so that it is possible to disconnect the supports from the brackets, the nuts of which have already been unscrewed. Remove the support (s).
16. Installation is carried out in the reverse order of removal. Treat the threads of the support fasteners with anaerobic sealant and ensure that the tightening torque specified in this chapter is maintained.
