Drain screw tightening torque:
27 N·m (2.7 kgf·m, 20 lb·ft)
TIP:
If a torque wrench is not available when you
are installing the drain screw, finger tighten
the screw just until the gasket comes into
contact with the surface of the drain hole.
Then tighten 1/4 to 1/2 turn more. Tighten
the drain screw to the correct torque with a
torque wrench as soon as possible.
(8) Add the correct amount of oil through the
filler hole. Put back the filler cap and the
dipstick. NOTICE: Overfilling the oil
could cause leakage or damage. If the
oil level is above the upper level
mark, drain until the level meets the
specified capacity.
