4.9. The heat exchanger oil - / cooling liquid


The heat exchanger (maslookhladitel) is connected with a circulating contour of oil both cooling liquid straight lines and retsirkulyatsionny pipelines. Pipelines are brought to the oil pump sideways via the oil pallet.

Below the operations which are carried out on the diesel engine by volume of 2,2/2,5 l are described.

1. Disconnect from the battery a "weight" wire (–).

The anticreeping code of radio is thus erased.

2. Unscrew the bottom cover of a motor compartment and remove it.
3. Merge engine oil.
4. Merge cooling liquid.
5. Unscrew the 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 shestigrannik (9) for an oil pipeline is established only at an 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).


1. Installation is made as it should be, the return to removal. Condensing rings of round section always are replaced with the new. Rings for hoses of cooling liquid before installation for protection from a slipaniye grease with cooling liquid, instead of engine oil.
2. The bolts, fixing the heat exchanger to the oil pallet, tighten with the moment of 10 N of m.
3. Establish the bottom cover of a motor compartment.
4. Fill in engine oil.
5. Fill in cooling liquid.
6. Connect a wire of "weight" of the battery (–).
7. Expose hours.
8. Set an anticreeping code of radio.
