Check
Rough check of the thermostat can be spent, having suspended it on a thread in the glass vessel filled with water and heating up water to boiling. At boiling of water the thermostat should open. Otherwise replace it.

The temperature of opening of the thermostat is put on the thermostat.

The thermostat which is not closed at water cooling, also is subject to replacement.

Installation

PERFORMANCE ORDER
1. Clear interfaced surfaces of a cover of the thermostat and a head of the block of cylinders.
2. Establish 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 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 a collar.
6. Fill in cooling liquid in cooling system.
7. Connect the accumulator.

PETROL ENGINES DOCH 1.6, 1.8 AND 2,0 L
