1. Open a cowl and examine podkapotny space. At survey of the engine pay attention to availability of cooling liquid in a broad tank, to an integrity of rubber hoses, a radiator...	2.... and thermostat cases.

Good advice The burst hose can be restored temporarily by means of an adhesive tape. Especially well the reinforced adhesive tape (for example, silvery color) which can be got in autoshops is suitable for this purpose.

At dribble of cooling liquid from under the case of the thermostat tighten bolts of its fastening. If tightening of bolts did not succeeded to eliminate dribble, then it is necessary to uncover and replace laying.

3. Examine connections with a radiator of the steam discharge and bringing hoses...	4.... connection of the taking-away hose with a branch pipe of a radiator and a branch pipe of the water pump.

5. Examine connections of hoses of the cooling system with heater radiator branch pipes...	6.... connection of bringing heater radiator hose with the union of a head of the block of cylinders...

7.... connections of the taking-away heater radiator hose...	8.... and a filling hose with a pipe of a small circle of circulation of cooling liquid.

9. Check connection of hoses with a broad tank.

Useful tips In a stopper of a broad tank two valves are installed: inlet and final. The final valve plays a large role in providing optimum temperature condition of the engine. It supports the excessive pressure not less than 0,145 MPas (1,45 kgfs/cm2) in system, providing temperature increase of the beginning of boiling of cooling liquid and preventing intensive steam formation. Unfortunately, when jamming the valve in a closed position at an overheat there is considerable excess of excessive pressure — more than 0,15 MPas (1,5 kgfs/cm2) that can lead to a rupture of a broad tank or failure of one of hoses. In turn, jamming of the valve in open situation leads to premature boiling of cooling liquid. Therefore once a year wash out a stopper of a broad tank flowing water. If there were doubts in serviceability of the valve, replace a stopper.
