Check of system of cooling on tightness

Defective places in system of cooling are the most easier for defining at the hot motor and, accordingly, working pressure in cooling system. But in this case for check of hoses gloves are necessarily necessary, differently it is possible to burn.

  • Whether pass hoses at a radiator and the engine, including hoses to heating system?
  • Cracks in hoses? Kneading, define, how much hoses are firm – in the latter case it is necessary to replace them immediately.
  • At разминании tubes it is possible to define and the damages formed as a result покусов of rodents.
  • How much the ends of hoses come on corresponding branch pipes?
  • Whether coupling bolts of collars are tightened?
  • The rusted collars can unexpectedly burst during a trip and at full working pressure in cooling system. To replace!
  • The workshop supervises tightness of system of cooling by the special air pump with a manual drive and a manometre.
  • This device is established on an aperture of a compensatory tank and pressure 1 bar is pumped up.
  • If within 1—2 minutes pressure does not go down, the cooling system is considered tight.
