?� Pit or gidropod?�mnik with stand (if the oil is not sucked).
?� Head to loosen the drain plug.
?� Special tool for loosening the filter (a filter wrench, strap wrench or tool HAZET 2172).
?� The capacity to collect oil (if the oil is not sucked) with a capacity of not less than 6 liters.

7. Remove the clamp.

Do not forget to remove the clamp, as otherwise not stech?�t separated oil to the oil pan, the engine will be sucked and will then be clogged air mass meter.
