THE GENERAL DATA

THE PETROL ENGINE

After rather long work of the car thin channels in a radiator can be hammered the rests of a cooling liquid and limy adjournment. Because of it cooling ability decreases, and the engine too heats up. Only installation of a new radiator in this case helps.

Removal


PERFORMANCE ORDER
1. Disconnect a weight wire (–) from the accumulator.
The prevention

The anticreeping code of radio is thus erased.


2. Merge cooling liquid.
3. Extend upwards fixing springs (33) casings of the fan.
4. Pull upwards a casing of the fan a little and lay it over the fan.
5. At cars with an automatic transmission disconnect from plugs suitable clamps маслопроводы (7/8), going from and to a check point, and turn off them on a radiator (4). Thus pay attention to ideal cleanliness. Connections before their removal outside clear spirit. Directly after that close маслопроводы plastic caps with rubber rings that on them the dirt could not get.
6. Remove from a radiator hoses for a cooling liquid, preliminary having weakened clips and having shifted them completely back.
7. Extend upwards fixing springs. Take a radiator upwards.

Installation


PERFORMANCE ORDER
1. Check up all hoses for giving of a cooling liquid on absence of cuts, cracks and other damages and if it is required, replace the damaged hoses. Check up rubber caps of fastening of a radiator and be convinced that they are in a good condition.
2. Insert from above a radiator so that fixing fingers of a radiator were grasped in rubber caps.
3. Insert above fixing springs for radiator fastening.
4. Spread hoses for giving of a cooling liquid and fix their clips.
5. If radiator hoses rigidly twirl on them накидные nuts with the moment 20 Н.м are still disassembled., remove clips.
6. Establish a fan casing, press it downwards and thus fix in lateral fixing plates on a radiator.
7. Insert the top spring clip of a casing of the fan.
8. Fill in cooling liquid.
9. Attach to the plug of the accumulator a weight wire.
10. Warm up the engine and check up tightness шланговых connections.
11. Check up level of a cooling liquid, if necessary add it.
12. At cars with an automatic transmission check up oil level in a check point.
13. Expose time for hours.
14. Enter for radio an anticreeping code.

Removal



PERFORMANCE ORDER
1. Disconnect from the storage battery a weight wire.
The prevention

The anticreeping code of radio is thus erased.


2. Merge cooling liquid.
3. The engine in volume of 2,0 l: remove upwards springs of a latch (15) on a fan casing.
4. The engine in volume of 2,0 l: pull upwards a casing of the fan a little and lay it on the fan.
5. The engine in volume of 2,2/2,5 l: remove hydraulic муфту the fan of system of cooling.
6. The engine in volume of 2,2/2,5 l: remove a fan casing.
7. At cars with an automatic transmission disconnect by means of suitable clamps clips of the oil lines going from and to a check point, and turn off them on a radiator. Thus pay attention to cleanliness, connections before removal clear outside spirit. Then put on on маслопроводы small plastic sacks with rubber rings that the dirt could not get into them.
8. Remove from a radiator (4) hoses for a cooling liquid, preliminary having weakened clips and having shifted them completely back.
9. Extend upwards fixing springs (15).
10. Remove a cable of management of a cowl.
11. Get upwards a radiator (1) together with an air line.
