  2. Warm up the engine to normal working temperature.

After a warming up of the engine put the gear shifting lever on "Neutral" (for And/t models put the gear shifting lever on a range of "R"), both establish the parking brake and block driving wheels.

  1. Start the engine the every speed of idling, and consider indicators компрессиметра. Razryazheniye should be within the following technical characteristics. Technical characteristics of a razryazheniye (at a sea level): 52.6-72.3 kPa (40-55 cm рт. St, 15.7 – 21.6 inch hg) on the specified speed of idling.
  2. After check attach a vacuum hose to an inlet collector.
