Changed my engine oil & filter yesterday.
Sequence (follow this entirely at your own risk....):
- Remove undertray - 6 bolts, 13mm socket.
- Drive van to get oil up to temp.
- Release oil filler cap.
- Remove sump drain plug - 19mm socket - leave oil draining.
- Remove oil filter drain - centre of oil filter housing cap. It will drain without hitting any items.
- Remove oil filter housing cap when housing has finished draining - 32mm socket.
- Remove old filter and both of the cap seals - replace all with new bits.
- Lubricate filter cap O rings with fresh oil.
- Refit oil filter housing drain in cap - don't over-tighten, just needs to be nipped up.
- Refit housing cap with new filter installed - hand tight then torque to 25Nm.
- Refit sump drain plug with new sealing washer - I actually fitted a new magnetic drain plug. Torque to 10Nm.
- Fill engine with fresh oil - 7.4 litres.
- Run engine & check for leaks.
- Refit undertray - and feel smug about a job well done.
