sensor; 7 — crankshaft position sensor connector; 8 — absolute pressure and
temperature sensor; 9 — ignition coils; 10 — oil level indicator; 11 — engine

When changing the engine oil, replace the oil filter. Drain the
used oil from the engine crankcase immediately after a journey
while it is still hot. In this case, the oil pours out quickly and
completely.
Remove the oil filter 10 (see Fig. 9.3) by turning it counter-
clockwise. When installing a new filter, make sure that the rubber
O-ring is in proper condition and lubricate it with engine oil,
turn the filter until the O-ring touches the plane on the engine
block and then tighten the filter with a 3/4 turn. Make sure no
oil leak exists.
With the engine warm and the lubrication system intact, the
emergency oil pressure warning lamp may be on at idle, but it
shall go out immediately after increasing the crankshaft rpm.
It is recommended to flush the engine lubrication system after
each two oil changes. For that purpose, drain the used oil, fill
in special flushing oil (VNIINP-FD) 3-5 mm over the "MIN"
