Change the oil on a warm engine. Unscrew the crankcase drain plug, drain the oil into a container and wait 10 minutes until it is completely drained. Close the plug and, without removing the oil filter, fill in VNIINP-FD flushing oil up to the min mark (2.9 l) on the oil level gauge. Start the engine and let it run on this oil for 10 minutes at the minimum engine speed.
Drain the flushing oil completely, remove the old oil filter using tool A.60312, install a new one (wrapped by hand only) and fill with 3.75 liters of oil, according to the season.
