The heat exchanger (oil cooler) is connected with a circulating contour of oil and cooling liquid direct and recirculation pipelines. Pipelines are brought to the oil pump sideways via the oil pallet. Below the operations which are carried out on the 2,2 / 2,5 l diesel engine are described.
Removal
| PERFORMANCE ORDER |
1. Disconnect a wire of "weight" from the battery (–).
Prevention
At the same time the anticreeping code of radio is erased.
|
| 2. Unscrew the lower cover of a motor compartment and remove it. |
| 3. Merge engine oil. |
| 4. Merge cooling liquid. |
|
5. Unscrew a bolt (2) and remove the hoses (1) connecting the heat exchanger to the pump of cooling liquid. Pay attention to assembly position of the holder of pipelines (shooter). |
|
6. Disconnect the heat exchanger from the oil pallet, turn off bolts (8). The bolt with an internal hexagon (9) for an oil pipeline is established only at the automatic transmission. |
| 7. Remove hoses of cooling liquid (1) with rings of round section (2). |
| 8. Remove oil pipelines (7) with rings of round section (6). |
|
Installation
| PERFORMANCE ORDER |
| 1. Installation is made as it should be, the return to removal. The condensing rings of round section are always replaced with new. Grease rings for hoses of cooling liquid before installation for protection from adhesion with cooling liquid, but not engine oil. |
| 2. Tighten the bolts fixing the heat exchanger to the oil pallet with m 10 N.' moment. |
| 3. Establish the lower cover of a motor compartment. |
| 4. Fill in engine oil. |
| 5. Fill in cooling liquid. |
| 6. Connect a wire of "mass" of the battery (–). |
| 7. Expose hours. |
| 8. Set an anticreeping code of radio. |
