GENERAL INFORMATION

PETROL ENGINE

After rather long operation of the car thin canals in a radiator can be filled the remains of cooling liquid and limy deposits. Because of it the cooling ability decreases, and the engine too heats up. In this case only installation of a new radiator helps.

Removal


PERFORMANCE ORDER
1. Disconnect a weight(s) wire from the accumulator.
Prevention

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


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

Installation


PERFORMANCE ORDER
1. Check all hoses for supply of cooling liquid for lack of cuts, cracks and other damages and if it is required, replace the damaged hoses. Check rubber caps of fastening of a radiator and be convinced that they are in good shape.
2. Insert from above a radiator so that fixing fingers of a radiator were taken in rubber caps.
3. Insert above the fixing springs for fixing of a radiator.
4. Spread hoses for supply of cooling liquid and record them clips.
5. If radiator hoses are still sorted, then rigidly put on them cap nuts with of 20 N.' moment of m, remove clips.
6. Establish a fan casing, press it down and at the same time record in the side fixing plates on a radiator.
7. Insert the top spring clip of a casing of the fan.
8. Fill in cooling liquid.
9. Attach a weight wire to the accumulator plug.
10. Warm up the engine and check tightness of hose connections.
11. Check the level of cooling liquid, if necessary add it.
12. At cars with the automatic transmission check oil level in the check point.
13. Expose time on hours.
14. Enter an anticreeping code for radio.

DIESEL ENGINE

Removal



PERFORMANCE ORDER
1. Disconnect a weight wire from the rechargeable battery.
Prevention

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


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