4.3.6. Check of hoses and connections of system of cooling

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

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

At a podtekaniye of cooling liquid from under the case of the thermostat tighten bolts of its fastening. If with a tightening of bolts to eliminate a podtekaniye it was not possible, it is necessary to uncover and replace laying.

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

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

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

9. Check connection of hoses with a broad tank.

Good advice In a stopper of a broad tank two valves are established: inlet and final. The final valve plays large role in providing an optimum temperature mode of the engine. It supports in system superfluous pressure not less than 0,145 MPas (1,45 kgfs/cm2), providing temperature increase of the beginning of boiling of cooling liquid and preventing intensive steam formation. Unfortunately, when jamming valve in a closed position at an overheat there is a considerable excess of superfluous 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, valve jamming 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.
