Routine maintenance

Check of a compression

Compression pressure on all four cylinders is checked as follows.

PERFORMANCE ORDER

Warm the engine. After a warming up stop the engine.

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

Disconnect a connector of a bunch of wires of a fuel injector.

the Head Sistema of ignition

(A): 09915-64510-001 (C): 09915-64510-002 (C): 09915-64530 (D): 09915-67010

Switch off coupling (to reduce initial load of the engine) for the M/T models, and press a pedal of management of supply of fuel against the stop completely to open a butterfly valve.

Start the engine with completely charged accumulator and read the maximum instrument of pressure on a kompressimeter. to kompressimetra

To measure compression pressure, start the engine, at least, on 250 revolutions per minute, by means of completely charged accumulator.

Compression pressure

	Compression pressure
Normal	1400 kPa (14.0 ^kg/cm2, 199.0 ps)
Limit	1200 kPa (12.0 ^kg/cm2, 170.0 ps)
The maximum deviation between two cylinders	100 kPa (1.0 ^kg/cm2, 14.2 ps)

item 5 – 7

After check insert spark plugs and knots of the coil of ignition and reliably connect a connector of a bunch of wires of a fuel injector.
