Removal
| PERFORMANCE ORDER |
1. Turn off рожковым a key накидную a nut, thus by means of a countersupport clamp a pulley of the pump for giving of a cooling liquid.
The prevention  The nut has the left carving.
|
| 2. Extend hydraulic муфту together with the fan. |
| 3. Unscrew 3 fixing bolts and separate the fan from муфты. |
|
Installation
| PERFORMANCE ORDER |
1. Connect муфту to the fan.
The prevention Correct assembly position of the fan is defined by means of the welded on edge.
|
| 2. Screw hydraulic муфту with the moment 10 Н.м. |
3. Insert hydraulic муфту together with the fan and screw with the moment in 40 Н.м. For this purpose it is required динамометрический a wrench with a nozzle рожкового a wrench.
The prevention The nut has the left carving.

THE 6-CYLINDER PETROL ENGINE
Removal
| PERFORMANCE ORDER |
| 1. Remove a fan casing. |
| 2. Unscrew a bolt (3) on hydraulic муфте the fan. Thus keep a pulley from rotation in an opposite side by means of a self-made key on лыске a disk (6). |
| 3. Take the fan together with hydraulic муфтой. |
|
Installation
| PERFORMANCE ORDER |
| 1. Thus insert the muftu-fan that welded on number of a detail was ahead from outside a radiator. |
| 2. Screw the muftu-fan with the moment 45 Н.м., thus keep a pulley from rotation in an opposite side. |
| 3. Establish a fan casing. |

THE DIESEL ENGINE IN VOLUME OF 2,0/2,2 L
Removal
| PERFORMANCE ORDER |
1. Unscrew () накидную a nut (2а) a wrench (5), thus fix a pulley of the pump of system of liquid cooling by means of a countersupport (9).
The prevention The nut has the left carving.
|
| 2. Take together with the fan (1) hydraulic муфту (2). |
| 3. Unscrew three fixing bolts (3) and separate the fan from муфты. |
|
Installation
| PERFORMANCE ORDER |
| 1. Insert муфту into the fan of system of cooling. By means of a ledge on a fan ring correct assembly position of the fan is defined. Marks "VORNE FRONT" specify in a movement direction. |
| 2. Screw hydraulic муфту the fan with the moment 10 Н.м. |
3. Insert муфту into the fan of system of cooling and together screw them on a shaft of the pump for giving of a cooling liquid with the moment 45 Н.м. For this purpose it is required динамометрический a key with a nozzle рожкового a key 36.
The prevention The nut has the left carving.

|
THE DIESEL ENGINE IN VOLUME OF 2,5 L
Removal
| PERFORMANCE ORDER |
| 1. Remove a casing of the fan and lay it over the fan of system of cooling. |
| 2. Unscrew hydraulic муфту together with the fan of system of cooling, including a bolt with internal шестигранником. Thus keep a pulley by means of a countersupport. |
| 3. Extend upwards the fan (1) together with муфтой (2) and its casing. |
| 4. Unscrew the fan with four bolts (4) from hydraulic муфты. |
|
Installation
| PERFORMANCE ORDER |
1. Insert hydraulic муфту into the fan of system of cooling and screw it with the moment 10 Н.м.
The prevention Marks "VORNE FRONT" specify in a movement direction.
|
| 2. Put together муфту with the fan of system of cooling and a fan casing. |
| 3. Screw the muftu-fan with the moment 45 Н.м., thus stop a pulley. |
| 4. Mount and adjust a fan casing. |
