4.9. The heat exchanger oil-/of a cooling liquid

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

The operations which are carried out on the diesel engine in volume of 2,2/2,5 l are more low described.

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

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 a bolt (2) and remove the hoses (1) connecting the heat exchanger with the pump of the cooling liquid. Pay attention to assembly position of the holder of pipelines (marksman).
6. Disconnect the heat exchanger from the oil pallet, turn off bolts (8). The bolt with internal шестигранником (9) for маслопровода is established only at an automatic transmission.
7. Remove hoses of a cooling liquid (1) with rings of round section (2).
8. Remove маслопроводы (7) with rings of round section (6).


1. Installation is made in an order, the return to removal. Condensing rings of round section always are replaced with the new. Rings for hoses of a cooling liquid before installation for protection from слипания grease with a cooling liquid, instead of engine oil.
2. Bolts, крепящие the heat exchanger to the oil pallet, tighten with the moment 10 Н.м.
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.
