Repair Sharan/Sharan Volkswagen>> Cooling system>> Radiator and fan>> Cover of a radiator and radiator check
The radiator serves for branch of warmth from cooling liquid as an air stream.
The system of cooling of the engine is under pressure. A radiator cover with laying tightly close a radiator, but thanks to specially picked up spring which has been built in a cover in case pressure in system of cooling rises to 140 — 180 kPas, the cover of a radiator opens. Pressure in system of cooling raises because of expansion of cooling liquid that leads to boiling temperature increase.

Fig. 186. Check of a cover of a broad tank by means of the delivery pump VW1274





Check of a cover of a radiator also is carried out by means of the delivery pump VW1274 (fig. 186) .
Tighten the pump VW1274 to a cover (see fig. 186 ) and increase with its help pressure until the cover will not open. The pressure size at which there should be a cover opening, should be between 140 and 180 kPas. If size another, it is necessary to replace a radiator cover.
