Filling the Oil Sump
Add fresh oil through the oil
filler cap on the valve cover.
After refilling the oil, run the engine for a few moments
while checking the engine's oil pressure. Make sure
there
is
no leakage around the new oil filter
or
from the
oil drain system, and stop the engine. Then check the
quantity of oil with the dipstick. Fill to, but not over, the
high mark on the dipstick, should the engine require ad-
ditional oil.
