The thermostat is established at engines in working volume of 1,1 and 1,3 l in the case 8 (cм. fig. Details of system of cooling of engines in working volume of 1,1 and 1,3 l) thermostat nests, and at engines in working volume of 1,6 and 1,8 l – in the lower part of the case 13 (see fig. Details of system of cooling of engines in working volume of 1,6 and 1,8 l) water pump.
Removal and installation
| PERFORMANCE ORDER |
| 1. To merge liquid from system of cooling of the engine. |
| 2. At engines in working volume of 1,1 and 1,3 l to disconnect a hose 12 (see fig. A radiator and the fan of system of cooling of engines in working volume of 1,1 and 1,3 l) from a cover 12 (cм. fig. Details of system of cooling of engines in working volume of 1,1 and 1,3 l). To unscrew bolts of fastening of a cover and to uncover 12 with a sealing ring 11. To take out the thermostat 10. |
| 3. At engines in working volume of 1,6 and 1,8 l to disconnect a hose 18 (cм. fig. A radiator and the fan of system of cooling of engines in working volume of 1,6 and 1,8 l) from a cover 5 (see fig. Details of system of cooling of engines in working volume of 1,6 and 1,8 l). To unscrew bolts 6 and to uncover 5 with a sealing ring 7. To take out the thermostat 8. |
| 4. To check the thermostat. For this purpose to measure length of the thermostat as it is specified in point 5. To suspend the thermostat in a vessel with the water which has been heated up to temperature 70–75 ° With so that it did not concern walls. Gradually to heat up water in a vessel, constantly mixing it that water temperature was identical in all volume. At temperature 88 ° About the valve of the thermostat should start to open. To heat up the thermostat to 102 ° With, at this temperature the valve of the thermostat should open completely. |
|
5. To measure length of the thermostat in a warm condition (And). Its length should increase by 7 mm. Let's to the thermostat cool down and measure its length in a cold condition (and). It should be same, as before heating. If the specified conditions are not carried out, the thermostat means is faulty and it is necessary to replace it. |
| 6. To establish the thermostat as it should be, the return to removal. At installation to replace a sealing ring, bolts of a cover of a nest of the thermostat to tighten the moment of 10 N · m (1,0 kgfs · м). |
