Examination
1. When checking, the engine should be slightly raised to relieve the load on 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 they cracking, are they peeling off from the metal base, or has the rubber hardened?. The destruction of the rubber block usually does not start 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 it hasn't already been done).
Warning. If your vehicle has a theft-protected audio system, make sure you have the unlock code for it before disconnecting the battery.
Replacement
Right support (from the passenger side)
7. The support that holds the power unit on the timing drive side is attached to the unit and to the bracket. mounted on the chassis. To replace the support, relieve it by supporting the engine from below with a hydraulic jack. To protect the pallet, place a wooden block on the jack head. Do not place a jack under the oil pan drain plug.
8. Unscrew the support clamp bolt, then the bolts securing the support to the engine 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, at the junction of the engine and the transmission (figure 16 10).
Application: If you only need to replace the front or rear mount, it is easier to remove the entire subframe than to lift the power unit enough to free it from the studs (see chapter 7).
11. To crush the front support, follow the steps in paragraphs. 7-9.

12. Installation is performed 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. Loosen the bolts that secure the support to the transmission, loosen and remove the tension bolt completely, then lift the power unit enough to allow the spore to be pulled out (figure 16.14).
15. Installation is carried out in reverse order.
Note: Before final tightening of fasteners, lower the power unit onto the supports 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 (Fig. 16.16). To access the support, remove the air intake duct and air cleaner (see chapter 4).
17. Support the power unit, unscrew the tie bolt, bolt and nut securing the support to the transmission and remove the support.
18. Install the spore 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. On most models there is another support under the junction of the engine and transmission (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.
21. 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.
Final tightening of all supports
22. When all supports are finally tightened, the vehicle should be horizontal 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.
