Maintenance
3. Open the cover at the rear right, then use a filter wrench to
turn filter cartridge (1) to the left to remove it.
4. Clean the filter holder (2), fill the new filter cartridge with
clean engine oil, coat the thread and packing surface of the
new filter cartridge with clean engine oil (or coat it thinly with
grease), then install it to the filter holder.
REMARK
Check that there is no old packing stuck to the filter holder
(2). If there is any old packing stuck to the filter, it will cause
leakage of oil.
5. When installing, tighten until packing surface contacts the
seal surface of filter holder (2), then tighten it a further 3/4 to
1 turn.
6. After replacing the filter cartridge, open the engine hood and
add engine oil through oil filler (F) to between the H and L
marks on dipstick (G).
7. Run the engine at idle for a short time, then stop the engine,
and check that the oil level is between the H and L marks (K)
on dipstick.
For details, see "Change oil in engine oil pan, replace engine
oil filter cartridge (4-78)".
