SOCH ENGINES OF 1,6 L
Prevention
At installation of the thermostat it is necessary to establish a new sealing ring.
Removal
| PERFORMANCE ORDER |
| 1. Remove a weight wire from the accumulator. |
| 2. Merge cooling liquid from the cooling system. |
| 3. Weaken a collar and disconnect the top hose from a thermostat casing on the right side of the engine. |
| 4. Take off a gear belt, an intermediate pulley, a pulley of the 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
|
|
A rough inspection of the thermostat can be carried out, having suspended it on a thread in the glass vessel filled with water and heating water to boiling. When boiling water the thermostat has to open. Otherwise replace it. |
Temperature of opening of the thermostat is put on the thermostat.
The thermostat which is not closed when cooling water is also subject to replacement.
Installation
| PERFORMANCE ORDER |
| 1. Clear the interfaced surfaces of a cover of the thermostat and a head of the block of cylinders. |
| 2. Install 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 by 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 by a collar. |
| 6. Fill in cooling liquid in the cooling system. |
| 7. Connect the accumulator. |

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