| PERFORMANCE ORDER |
| 1. Remove a weight wire from the accumulator and merge cooling liquid from cooling system. |
| 2. Unscrew screws, take assembly percussion caps and remove plastic casings from two parties of a radiator (see fig. Unscrewing of the screw of fastening of a plastic casing of a radiator, Extraction of an assembly percussion cap of fastening of a plastic casing of a radiator, Placement of elements of fastening of a plastic casing of a radiator). |
| 3. On models with petrol the engine ми unscrew screws and remove system of pipes of an air inlet from a forward cross-piece. |
| 4. Weaken collars and remove the top and bottom hose from radiator branch pipes. At existence remove perelivny a hose from the top part of a radiator (see fig. Removal of a hose from the top branch pipe of a radiator on the 6-cylinder petrol engine, Removal of a hose from the bottom branch pipe of a radiator on the 6-cylinder petrol engine, Removal of a hose from the top branch pipe of a radiator on the 4-cylinder petrol engine, Removal of a perelivny hose from the top part of a radiator). |
| 5. Remove the clips, fixing the top part of a casing of the fan of a radiator to a radiator. Lift a casing and place it over a krylchatka of the fan of a radiator. Remove a clamp, disconnect directing casing, move it to the left and take from a motor compartment (see fig. Removal of the clips, fixing the top part of a casing of the fan of a radiator, Removal of a casing of the fan of a radiator and its placement over a krylchatka of the fan, Removal of a clamp of a directing casing, the Detachment of a directing casing, Removal of a clip of a directing casing, Extraction of a directing casing from a motor compartment). |
| 6. On models with an automatic transmission press the hoses going to the heat exchanger of transmission liquid, then separate connections and remove hoses from the heat exchanger (see fig. A hose detachment from the heat exchanger of transmission liquid on models with the 6-cylinder petrol engine, Places of connection of hoses of supply of cooling liquid to the heat exchanger on models with 4-cylinder petrol engines). Close the open ends of tubes jams. |
| 7. Remove the metal or plastic clips, fixing a radiator to a body. Remove a radiator, lifting it up from rubber pillows in the lower part (see fig. Removal of a metal clip of fastening of a radiator, the Arrangement of a plastic clip of fastening of a radiator, radiator Extraction from a motor compartment on models with 6-cylinder petrol engines, radiator Removal on models with 4-cylinder petrol engines). Remove a casing of the fan of a radiator from a krylchatka of the fan. |
|
Check
| PERFORMANCE ORDER |
| 1. If the radiator acted in film in connection with capacity reduction, wash out it a water stream in two directions. |
| 2. Outside blow a radiator the compressed air. |
| 3. If the radiator proceeds, do not try to make or solder a leakage place since plastic details of a radiator will be damaged. |
| 4. The insignificant leakage of a radiator can be eliminated with use of hermetic of a radiator. |
| 5. Check a condition of the bottom rubber support of a radiator and if necessary replace them. |
|
Installation
|
|
The bottom fastenings of a radiator should be established in rubber condensing rings. |
| PERFORMANCE ORDER |
1. Installation is made in sequence, return to removal taking into account the next moments:
– check that the bottom ledges on a radiator were established in rubber support;
– check that all hoses are correctly connected and reliably fixed by collars;
– in summary fill in cooling liquid in cooling system. |
