Turn engine oil filter cartridge (6) counterclockwise by us-
ing the filter wrench, and remove it.
10. Clean the filter head.
11. Fill the new filter cartridge with clean oil, coat the packing
face and thread with oil (or coat thinly with grease), then
install the filter cartridge.
12. After the packing surface reaches the filter head, tighten
the filter cartridge 3/4 to 1 turn.
13. After replacing the filter cartridge, refill with engine oil
through oil filler port (F) until the oil level is between H and
L marks on dipstick (G).
14. Run the engine at low idle for a while and then stop it.
15. Check that the oil level is between H and L marks on the
dipstick.
16. For the checking method, see "METHOD FOR CHECKING
OIL LEVEL IN ENGINE OIL PAN, ADDING OIL (3-135)".
REMARK
When the ambient temperature is low, water or emulsified matter may stick to the dipstick, oil filler cap, etc. or
the drained oil may be milky white because of water vapor in the blowby gas. However, if the coolant level is
normal, it is not a problem.
There is no problem even if the emulsified matter cannot be removed completely after changing oil.
