On illustrations the thermostat disconnected from a thermostat cover is shown. The thermostat is built in a cover and can be checked in a set. |
Petrol engine
Removal
|
|
The thermostat is built in a cover of the thermostat and can be replaced only complete with it.
|
|
At the hot engine before opening of a broad tank cover it with a thick rag to exclude a burn owing to influence of hot cooling liquid and steam. It is necessary to uncover only at a temperature of cooling liquid below + 90 °C. |
1. Merge cooling liquid in capacity as it is described in
the Section Replacement of Cooling Liquid - general comments.
|
2. Uncover the engine in front (2) and at the left (1). |
3. Remove hoses of cooling liquid from a radiator and a broad tank on a thermostat cover. Previously release collars and displace them completely back. 4. Turn off a cover of the thermostat and remove it together with the thermostat.
|
The thermostat and cover of the thermostat form uniform knot. At removal the thermostat can be damaged and is not subject to the subsequent installation. |
5. Remove laying of the case of the thermostat and clear sealing surfaces.
|
|
Installation
|
1. Establish a new sealing ring, a thermostat cover with the thermostat and fix by the moment 10 Nanometers. 2. Put on hoses of cooling liquid connecting unions and fix by collars.
|
At the same time check a condition of hoses and collars, if necessary replace. |
3. Establish forward and left covers of the engine. |
|
Diesel engine
Only differences from the petrol engine are described.
|
1. Disunite the socket of a sensitive element of the sensor of temperature (14). 2. Disconnect the holder of a fuel-supply line from the thermostat case. 3. Disconnect hoses of cooling liquid and a hose of ventilation (1) at the case of the thermostat (1). 4. Unscrew the case of the thermostat (12). Moment of an inhaling of 9 Nanometers. |
