  • We'll be working on my old Mercedes today, changing the Oil and Filter
  • Pop the bonnet, or in USA "pop the hood", in RHD cars, the catch is on the left side next to the door
  • It's two-hands to open the actual bonnet as there are 2 ajar catches on this model - one on either side near the sides of the front of the bonnet/hood

Jacking points

  • I put my hydraulic jack in the centre of the front of the sub-frame
  • I put the jack stands under the frame/unibody box sections
  • I use cardboard instead of a creeper - more leverage, and easy clean up

Removing the drain bolt

  • I used a 14mm hex or "Allen" key
  • It appears some of the previous oil-changers over the last 40 years did not have the correct tool as there are vise-grip marks on the bolt

Remove old filter

  • Check your new filter etc, I used Hengst E117H D07, but last time I used Mann H720X, both kits came with new o-rings and copper crush-washers
  • The oil filter is a cartridge-in-housing type located on the left-side of the engine block
  • I only had room for a wrench/spanner and had to work it a bit before loosening it with my fingers

Drain filter housing and old filter

  • Before removing the oil filter housing fully, move your catch pan under the area to catch the mess
  • Clean around the housing mounting plate area with a clean-ish rag, I use 2 grades of rag, the super-oily one first to pick up the bulk of the oil, then a cleaner rag after
  • I used a small pick to pull out the old o-ring - also check you don't misplace the washer on the long bolt

Clean out the housing and install new filter

  • Clean out the filter housing with your rags etc, then install a new o-ring if your kit came with one
  • Oil the new o-ring for re-installation
  • Place the new filter cartridge in the housing and insert the bolt with washer on it
  • Hold the bolt in and thread your hand down next to the block, lucky these old cars have heaps of space to work/see
  • Tighten the bolt down, but don't over-tighten as it's only a cast-metal housing

Ensure your drain bolt and filter are tight

  • Tighten your drain bolt and clean the area around the bolt with a rag
  • Check the area for leaks after filling
  • As you can see, my old filter was a Mann H720

Lower the car

  • Lift the car up from that front sub-frame lifting area and remove your jack-stands
  • Then gently lower the car so it's level for filling

Fill the car

  • I usually clean around the Oil fill cap with a rag
  • The dip-stick on this engine is next to the spark-plug wires
  • I used a stubby big-mouth funnel
  • I used 20W-50 for this old car, it needed about 5.5L or so

Conclusion

Fresh oil and filter installed :)
