1. Disconnect a wire of "weight" (–) of the battery.

At the same time the anticreeping code of radio is erased.

2. Remove a casing of the fan (7) and put from above the fan.
3. Remove an air hose (21), having disconnected the fixing collar.
4. Disconnect cable channel (3) from a forward wall of a body.
5. Remove the lower cover of a motor compartment.
6. Merge cooling liquid.
7. Lower engine oil.
8. Unscrew a forward exhaust pipe from a collector.
9. Unscrew arms of the holder of an exhaust pipe from the transmission.
10. Remove the oil heat exchanger / cooling liquid (4).
11. Remove the stabilizer.
12. Disconnect hoses of cooling liquid from a head of the block of cylinders and a pump housing of cooling liquid, previously having weakened and having cast away the fixing collars.
13. Disconnect a positive cable (X4) from its place of connection to the lower part of the car and put on the engine.
14. Unscrew the speed sensor.
15. Disconnect the plug of the sensor of level of oil (22).
16. Turn off behind the lower bolts (14) of a support of the engine.
17. Unscrew in front the lower bolts (12) of a support of the engine.
18. Automatic transmission: unscrew the holder of an oil pipeline of the transmission (11/13) from a transmission cap.
19. Pick up the engine for forward and back eyes.
20. Unscrew fastening bolts (6/6a) of the oil pallet. If it is necessary, turn off the holder (10) of electrical wire of the sensor of level of oil (543), and also a wire of "weight" (w11/1) from a transmission cap (at the automatic transmission: set of electrical wires of the transmission (15/16)).
21. Raise the engine as it is possible more horizontally.
22. Take the oil pallet (8) in the direction of the movement from below in front. In case of need slightly turn a bent shaft. At the automatic transmission slightly remove transmission oil pipelines aside. Track that the adjusting plug (17) did not drop out.
23. Carefully clear the sealing surfaces of the oil pallet and a case of a bent shaft.


1. Check whether there is in the motor block an adjusting plug (17).
2. Record by means of sealant, for example, of Omnifit-FD, new sealing laying (9) in the motor block.
3. Install the oil pallet, having oriented it concerning a transmission prileganiye surface, and evenly manually twirl bolts. Then alternately tighten bolts with the next moments:
1. Bolt of M 8 x 40 - 25 N. of m.
2. Bolt of M 6 x 35 - 10 N. of m.
3. Bolt of M 6 x 85 - 10 N. of m.
4. Bolt of M 6 x 20 - 10 N. of m.
5. Bolt of M 10 x 40 - 40 N. of m.
4a. A bolt of M 6 x 20 (with an internal hexagon) – 10 N. of m.
4b. A bolt of M 6 x 75 (with an internal hexagon) – 10 N. of m.
4a and 4b – only at the automatic transmission


If the oil pallet is not oriented in the direction of the transmission, then subsequently it can lead to emergence of noise.

3. Lower the engine.
4. Put on the oil level sensor plug.
5. Screw the speed sensor.
6. Connect a positive wire to the lower party of the car at the left.
7. Put on hoses of cooling liquid a head of the block of cylinders and a casing of the pump of cooling liquid and fix by collars.
8. Install the stabilizer.
9. Install the oil heat exchanger / cooling liquid.
10. Fasten a forward exhaust pipe to a collector, to an arm of the holder of an exhaust pipe at the check point.
11. Establish the lower cover of a motor compartment.
12. Establish a fan casing, adjust and fix by clips.
13. Put on an air hose and fix by a screw collar.
14. Fill in engine oil.
15. Fill in cooling liquid.
16. Attach "mass" of the battery (–).
17. Expose hours.
18. Set an anticreeping code of radio.
19. Start the engine and check tightness of the oil pallet.
