Note. Powertrain suspension mounts rarely need attention, but damaged pads should be replaced without delay to avoid increased stress and premature wear on transmission line components.
On the models under consideration, the suspension of the power unit is implemented using four rubber-metal supports. With the right front and rear supports, the engine block is attached to the load-bearing cross beam laid from below. The left front and rear support attach the transmission part of the unit to the vehicle frame.
Examination
1. To check, it is necessary to slightly raise the engine, completely unloading the supports.
2. Jack up the car and put it on stands. Hang the unit from above on a winch or beam.
3. Check the mount pads for cracks, signs of rubber hardening and delamination from the center metal bushings.
4. Estimate the amount of play between the support assemblies and the power unit / vehicle frame (use a pry bar or a large screwdriver as a lever). If there is any slack, lower the machine and tighten the support fasteners.
5. Pillows must be treated with a special protective compound to avoid rubber destruction.
Replacement
Disconnect the negative cable from the battery.
Attention! If the stereo system installed in the car is equipped with a security code, before disconnecting the battery, make sure that you have the correct combination to activate the audio system! Apply the parking brake, jack up the front of the vehicle and place it on jack stands. Remove the crankcase protection.
Front and rear engine mounts (rights)
1. Hang the unit from above.
2. Turn out through bolts of fastening of support to a cross beam.
3. Turn out fixing bolts and remove a cross beam from the car chassis.
4. Turn out through bolts of fastening of support to arms on the block of the engine.
5. Installation is carried out in the reverse order.
Note. The final tightening of the support fasteners with the required force should be carried out only after lowering the power unit to its normal position. Proceed to the procedures for the final stage of tightening the fasteners.
Front and rear transmission mounts (left)
transmission (left) the side of the power unit is also fastened by means of two supports - front and rear.
Front left support
1. Support the transmission under the dome with a jack. Turn out a through bolt of fastening of a support to the chassis and three bolts of its fastening to transmission. Remove the support assembly.
2. Installation is carried out in the reverse order.
Note. The final tightening of the support fasteners with the required force should be carried out only after lowering the power unit to its normal position. Proceed to the procedures for the final stage of tightening the fasteners.
Rear left support
1. Working under the vehicle, remove the nuts securing the support bracket to the transmission case.
2. The through bolt securing the support to the chassis bracket is given from above, - first remove the air cleaner assembly with the intake sleeve.
3. Lower the transmission until the transmission bracket is clear of the mounting studs, then remove the support.
4. Installation is carried out in the reverse order.
Note. The final tightening of the support fasteners with the required force should be carried out only after lowering the power unit to its normal position. Proceed to the procedures for the final stage of tightening the fasteners.
The final stage of tightening the fasteners of all supports
In order to maximize the service life of rubber-metal supports and reduce the level of noise and vibration, the final tightening of the support fasteners with the required force should be carried out after lowering the power unit to its normal position (the vehicle must be parked on a level surface).
Note. The threaded part of the fastener should be lubricated with a special sealant to fix the threaded connections. Make sure that the rubber bushings are not twisted or displaced from their seats. If more than one support was replaced, as well as when installing the power unit, the support fasteners must be tightened in the following order:
- a) Bolts of fastening of a cross beam;
- b) Right rear support;
- c) Left front support;
- d) Right front support;
- e) Left rear support.
