Check of depression of the engine

Razryazheniye of the engine, being created in a soaking-up branch pipe, is a good indicator of a condition of the engine. There is the following procedure of check of a razryazheniye:


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

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

  1. Switch off the engine and disconnect a vacuum hose from an inlet collector.
  1. Attach special tools (компрессиметр and connection of hoses) to a vacuum hose and an inlet collector.
    • Special tool:
      • (А): 09915-67311
      • (В): 09918-08210
    • Original details of Suzuki:
      • (С): Hose 09355-35754
      • (D): Tee 09367-04002
  1. Start the engine the every speed of idling and consider indicators компрессиметра. Razryazheniye should be within technical characteristics. Technical characteristics of a razryazheniye: 52.6-65.8 kPa (40-50 cm рт. St, 15.7 – 19.7 inches hg) on the specified speed of idling.
  2. After check remove компрессиметр and connection of hoses.
  3. Connect a vacuum hose to an inlet collector.
