Oil Pan Drain Plug
After draining the oil, discard the
washer and replace with a new copper
sealing washer, torque the bolt to 44
lb-ft (60 Nm).
Inspection of the Engine Oil
Level
NOTE
It takes approximately 15 minutes
for all the oil to run into the sump
when the engine is ‘warm.’ If the
level is checked immediately after
switching off the engine, the dipstick
will show a low oil level.
1. Make sure
that the vehicle frame
rail is standing on a at and level
surface.
2. Make sure
that the vehicle is
horizontal, both lengthwise and
crosswise. Check this carefully
on a vehicle with air suspension.
Note that the engine may be
inclined up to 4° depending on the
vehicle model and wheelbase.
3. Twist
the dipstick handle to unlock
it, then pull the dipstick out of the
holder.
4. Wipe the
dipstick clean with a
lint-free cloth.
5. Place the
dipstick back into the
holder.
6. Pull the
dipstick out again and
check the oil level. The oil level
should always be between the 2
marks on the dipstick.
