Check of pressure of oil

Before checking pressure of oil, check the next moments:

  • Oil level in an oil pan. If level of oil is low, add oil to a mark of level of complete filling (1) on oil щупе.
  • Quality of oil. If oil lost color or worsened, change it. See the table in the Section Engine, Head Maintenance and greasing to receive recommendations about use of concrete type of oils.
  • Oil leaks. If leak is found, eliminate it.

1 — level of complete filling
2 — a mark of low level of filling


  1. Take out the relay of pressure of oil (1) of the block of cylinders.
1 — the relay of pressure of oil
2 — the oil filter
  1. Insert the special tool (oil щуп) into the formed empty opening. Special tool: (А) — 09915-77311.
  1. Start the engine and warm up it to normal working temperature.

Be convinced that the lever of gear shifting costs 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. After warming up increase speed to 4,000 revolutions per minute and measure pressure of oil. Technical characteristics of pressure of oil: 330-430 kPas (3.3 – 4.3 kg/cm2, 46.9 – 61.1 пси) at 4000 revolutions per minute (about/m).
  2. Muffle the engine and take out oil щуп.
  1. Before delivering to the relay of pressure of oil into place, do not forget to wrap up its carving a sealing tape (1) and to fasten the relay to the specified rotating moment.
The rotating moment of an inhaling: the relay of pressure of oil (and) — 14 N • m (1.4 kg-m, 10.5 pound on foot).

If the edge of a sealing tape supports a relay carving, cut off it.

  1. Start the engine and check the relay of pressure of oil on a leakage.
