ENGINES SOCH OF 1,6 L
The prevention
At thermostat installation it is necessary to establish a new sealing ring.
Removal
| PERFORMANCE ORDER
|
| 1. Remove a wire of weight from the accumulator. |
| 2. Merge cooling liquid from cooling system. |
| 3. Loosen the a collar also disconnect the top hose from a thermostat casing on the right party of the engine. |
| 4. Remove a gear belt, an intermediate pulley, a pulley of a camshaft and a back casing of a gear belt. |
| 5. Unscrew bolts and uncover the thermostat a head of the block of cylinders. |
| 6. Take the thermostat from a casing and remove a sealing ring. |
|
Check
|
|
Rough check of the thermostat can be spent, having suspended it on a thread in the glass vessel filled with water and heating up water to boiling. At boiling of water the thermostat should open. Otherwise replace it. |
The temperature of opening of the thermostat is put on the thermostat.
The thermostat which is not closed at water cooling, also is subject to replacement.
Installation
| PERFORMANCE ORDER
|
| 1. Clear interfaced surfaces of a cover of the thermostat and a head of the block of cylinders. |
| 2. Establish the thermostat in a head of the block of cylinders together with a new sealing ring. |
| 3. Establish a cover of the thermostat and fix bolts. |
| 4. Establish a back casing of a gear belt, a camshaft pulley, a gear belt and an intermediate pulley. |
| 5. Connect the top hose to the thermostat and fix a collar. |
| 6. Fill in cooling liquid in cooling system. |
| 7. Connect the accumulator. |

PETROL ENGINES DOCH 1.6, 1.8 AND 2,0 L
Removal
| PERFORMANCE ORDER
|
| 1. Remove a wire of weight from the accumulator. |
| 2. Merge cooling liquid from cooling system. |
| 3. Loosen the a collar also remove the top hose from a thermostat cover. On engines of 1,6 l the thermostat cover is established to the case attached by bolts by the forward end of the engine. On engines of 1,8 and 2,0 l a cover the thermostat fastens bolts directly to a head of the block of cylinders. Thus it is necessary to remove in addition small hose. |
|
4. Unscrew bolts and uncover the thermostat in which the thermostat (on a photo – the thermostat of petrol engine DOCH 1,6) is fixed. |
| |
5. On engines of 1,6 l remove a sealing ring. |
| 6. Whether on engines of 1,8 2,0 l remove a lining. |
