5.4. Removal, check and installation to the place of the thermostat
CheckRough check of functioning of the thermostat can be carried out by suspension of the thermostat on a string in the pan filled with water. Water needs to be warmed before boiling - the thermostat has to open. If the thermostat does not open, it should be replaced.
In the presence of at your disposal thermometer it is possible to determine the exact temperature of opening of the thermostat; compare the received value to value, provided in Specifications. Temperature of opening of the thermostat also has to be marked on the thermostat case.
The thermostat which is not closed when cooling water is also subject to replacement.
Installation into placeInstallation is carried out as it should be the return to a removal order. At the same time it is necessary to remember the next moments:
a) Examine a sealing ring regarding detection of signs of damages or pollution, if necessary replace it.
b) Make sure that the thermostat is installed into place correctly (as it was noted at removal). The opening for production of air has to appear in the top part of the thermostat.
c) Where is available, install the air cleaner and/or an inlet air sleeve of the air cleaner (see the corresponding part of the Head Toplivnaya and exhaust systems).
d) In conclusion fill in the cooling system (see the Head Routine maintenance).
