Removal and thermostat installation/check

The thermostat when heating the engine opens a contour of course of cooling liquid through a radiator. If the thermostat because of malfunction remains is closed, the engine overheats. It is visible on increase of indications of the index of temperature on the dashboard while the radiator remains cold. The faulty thermostat also can remain abroach the ambassador of cooling of liquid. It is visible to that the engine does not reach or reaches very slowly the working temperature, or in the winter the heater does not reach the full capacity.

If the engine after a short trip becomes hot, maybe, that the radiator got littered because of lime adjournment, the fan failed or the belt (except the diesel engine) became torn maple.

The thermostat is on the left side in a head of cylinders behind an inlet branch pipe of cooling liquid.



    To merge cooling liquid and to bring together her, see. Section Routine maintenance.
    To disconnect a hose of cooling liquid, previously having weakened and having completely shifted a collar.
    To disconnect the thermoswitch tip-1-. The thermoswitch is on a final branch pipe of cooling liquid-3-. To weaken 2 bolts of fastening and to remove the final union-3-with laying-4-and the thermostat-5-.



    Slowly to heat up the thermostat in capacity with water. Thus the thermostat should not concern vessel walls. The thermostat should be completely shipped in water. To supervise temperature the suitable thermometer.
    At temperature +82°С (diesel engine: +86°С) the thermostat should start to open.

The opening temperature depending on the thermostat can differ. Its value costs on the thermostat.

    At temperature +95°С (diesel engine: +100°С) the thermostat should be completely open, it means that the zaslonka should depart from an emphasis at least on 8,5 mm. To check, that when cooling the thermostat was completely closed, otherwise it is necessary to replace it.



    To insert the thermostat into the case so that the pin was over a zaslonka. To insert new laying of the thermostat by the pressed party to a head of cylinders. To tighten fastening bolts with effort of 25 Nanometers. To connect the tip.
one-stage type
    To attach a hose of cooling liquid and to fix a collar.
    To fill in cooling liquid, see. Section Routine maintenance. To warm up the engine and to check unions on tightness, probably carefully to tighten fastening bolts.
