Hongqi, transfer case oil change in Umm al-Fahm

Hongqi, transfer case oil change in Umm al-Fahm.
To change the transfer case oil, it is required to heat up the transmission first (for this, the car must travel a certain distance), after which it is checked for oil leaks. Then the metal or plastic protection is removed, the filler and drain plugs are removed. The old oil is drained into a container. The transfer case is flushed, the hole is cleaned. The drain plug is closed and fresh oil is poured up to the level of the plug.
