Examination
1. When checking, the engine should be raised significantly to remove the load from its supports.
2. Raise the vehicle and support it on stands. Place a hydraulic jack under the engine, placing a wooden block on its head to avoid damaging the oil pan. Carefully lift the engine with a jack to relieve the load on the supports.
Caution! DO NOT work under the engine if it is supported only by a jack.
3. Inspect the engine mounts. First of all, pay attention to the rubber blocks - are there any cracks, separation from the metal base, or has the rubber hardened?. The destruction of the rubber block usually starts from the central hole.
4. Check for play in the supports. To do this, insert a strong screwdriver or crowbar into the support and rock the engine relative to the support. If play is evident, lower the engine and tighten the mount fasteners.
5. To reduce the likelihood of rubber decomposition, the supports should be coated with a protective compound.
6. Disconnect the negative battery cable, apply the parking brake, chock the wheels, raise the front of the car and place it on stands (if this has not already been done).
Caution: If your vehicle has a theft-protected audio system, make sure you have the unlock code before disconnecting the battery.
Replacement
Right support (from the passenger side)
7. The support supporting the power unit from the side of the timing mechanism drive is attached to the chassis of the unit. To replace the support, relieve it by lifting the engine from above using the lifting eye or supporting the engine from below with a hydraulic jack. To secure the pallet, place a wooden block on the jack head.
8. Unscrew the support clamp bolt, then the support mounting bolts to the chassis and pull out the rubber block (figure 16.8).
9. Installation of the support is carried out in reverse order.
Note: Before final tightening of fasteners, lower the power unit and remove the supporting jack. If several supports were replaced, then the order of their final tightening see. below.
Front support
10. The front support is located between the engine and the radiator (figure 16.10).
11. To remove the front support, follow the steps in paragraphs. 7-9.
12. Installation is carried out in reverse order.
Note: Before final tightening of fasteners, lower the power unit and remove the supporting jack. If several supports were replaced, then the order of their final tightening see. below.
Rear support
13. If the intake manifold is not removed, access to this support will be difficult and is only possible from below. Release the tie bolt and lift the power block to remove the load from the support.
14. Unscrew the nuts securing the support to the subframe. unscrew the clamping bolt completely and pull it out, and lift the power unit so that it becomes possible to pull out the support (figure 16.14).
15. Installation is carried out in reverse order.

Note: Before final tightening of fasteners, lower the power unit and remove the supporting jack. If several supports were replaced, then the order of their final tightening see. below.
Left support (from the driver's side)
Upper support
16. The driver's side support is attached to the top of the transmission and to the chassis (figure 16.16).
17. Support the power unit, unscrew the tie bolt, bolt and nut securing the support to the transmission and remove the support.
19. Install the support in reverse order.
Note: Before final tightening of fasteners, lower the power unit and remove the supporting jack. If several supports were replaced, then the order of their final tightening see. below.
Lower support
19. The lower support connects the transmission to the subframe (figure 16.19).
20. Support the power unit. Unscrew the two bolts securing the support to the transmission and the two nuts securing it to the subframe.
Final tightening of all supports
21. When final tightening of all supports, the vehicle should stand horizontally, and the weight of the power unit should rest on the supports. Fill the threaded connections with anti-loosening compound. Tighten all fasteners on all supports first by hand, then gradually tighten them until the required torque is reached.
