  2. Warm up the engine to normal working temperature.

After an engine warming up put the gear change lever on "Neutral" (for models А/Т put the gear change lever on a range Р), both establish a lay brake and block приводные wheels.

  1. At the disconnected engine disconnect a vacuum hose of a regulator of pressure of fuel from an inlet collector and connect a tee, hoses and the special tool (компрессиметр and the hinge) between an inlet collector and the disconnected vacuum hose.

  1. Start the engine with the specified speed of idling, and consider indicators компрессиметра. Разряжение should be within following technical characteristics. Technical characteristics разряжения (on a sea level): 52.6 – 72.3 кПа (40 – 55 sm рт. ст, 15.7 – 21.6 inch hg) on the specified speed of idling.
  2. After check attach a vacuum hose to an inlet collector.
