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.
