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. 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.
