Check of depression of the engine

The discharge of the engine which is created in the soaking-up branch pipe is a good indicator of a condition of the engine. There is a following procedure of check of discharge:

 PERFORMANCE ORDER

    Warm the engine up to the normal working temperature and be convinced that idling of the engine conforms to technical requirements.

After a warming up of the engine put the gear shifting lever on neutral (for the And/T models put the gear shifting lever in position "P"), both install the parking brake and block driving wheels.

    Switch off the engine and disconnect a vacuum hose from an inlet collector.
    Attach special tools (компрессиметр and connection of hoses) to a vacuum hose and an inlet collector.
      Special tool:
        (A): 09915-67311 (C): 09918-08210

    Start the engine with the specified speed of idling and consider indicators of a kompressimetr. Discharge has to be within technical characteristics. Technical characteristics of discharge: 52.6 – 65.8 kPa (40 – 50 cm рт. St, 15.7 – 19.7 inches hg) at the specified idling speed. After check remove компрессиметр and connection of hoses. Connect a vacuum hose to an inlet collector.
