Oil filter

Part numbers

Very important: The correct filter is a fleece filter. Do not make the mistake of buying the cheaper paper filter.

  • OE - A0001802609 (18 EUR)
  • OEM - MANN-FILTER HU 718/5 x (8 EUR)
MANN-FILTER is OEM for W220 oil filter

Engine oil change procedure

See below for the correct type of oil filter.

Tips

  • M112/M113 oil capacity is 8 liters.
  • Oil should be 140°F-160° F [60°-71°C].
  • If using the suction method, cut the end of the tube at a 45 degree angle.
  • Warm the engine slightly so the oil flows easily and then it usually won't suck the tube closed.
  • Run the engine for 5 to 10 minutes to heat up and thin the oil.
  • Turn off engine prior to removing oil.
  • Make sure the car is level. If not, you won't be getting all of the oil out of the pan, no matter which method you use.
  • Forget about refilling the new oil via the Oil Filler Cap. While you have the oil filter assembly out, pour the fresh oil down that huge hole. Less chance to spill, no funnel needed and no funnel to clean up afterwards.
  • If using the oil drain method be sure to put the drain plug back before refilling.

Oil cooler

Remove/install oil-water heat exchanger at oil filter

  • 2 - Fan shroud
  • 3 - Oil filter housing cap
  • 4 - Coolant line
  • 5 - Coolant line
  • 6 - Oil/water heat exchanger
  • 7 - Sealing rings
  1. Unclip cover on front side of engine
  2. Remove engine cover with integrated air filter. Remove engine cover or air filter by pulling it vertically up and off the cylinder head covers.
  3. Remove fan shroud (2) together with electric fan. Before removal of fan shroud (2) disconnect connector for electric fan.
  4. Remove electric fan
  5. Unscrew oil filter housing cover (3)
  6. Drain coolant at radiator. Do not open cooling system unless coolant temperature is below 90°C. Open cap slowly and release the pressure. Do not pour coolant into beverage containers. Wear protective gloves, protective clothing and safety glasses.
  7. Detach coolant lines (4, 5) from oil-water heat exchanger (6)
  8. Remove air pump
  9. Detach oil-water heat exchanger (6) from oil filter housing. Installation: Install new sealing rings (7).
  10. Install in the reverse order
  11. Inspect cooling system for leaks

Torque specifications:

  • Screw cap on oil filter: 25 Nm
  • Oil-water heat exchanger on oil filter housing: M112 11 Nm; M113 9 Nm

Replacing heat exchanger and oil filter housing seals

Heat exchanger and oil filter

A common source of engine oil leaks are faulty seals at heat exchanger (17 and 23) and oil filter housing (35). They can be easily replaced during regular oil flush, but require a 46mm socket.

Parts:

  • Sealing ring: heat exchanger on oil filter hoising: A1121840261 (Swag 10949403 / Febi bilstein 49403)
  • Sealing ring: heat exchanger on oil filter hoising: A1121840361 (Febi bilstein 49402)
  • Sealing ring: oil filter housing on timing case: A1121840061 (Elring 137100)
