Changing the Engine Oil and

Replacing the Engine Oil Filter

Element

The engine oil on a new engine becomes

contaminated from the initial break-in of

internal parts. It is very important that the

initial oil replacement is performed as

scheduled.

It is easiest and most arailable to drain the

engine oil after operation while the engine

is still warm.

WARNING

Burn Hazard.

If you must drain the engine oil while it

is still hot, stay clear of the hot engine

oil to avoid being burned. Always wear

eye protection.

1. Turn the engine off.

2. Remove the engine oil dipstick. Attach

the oil drain pump (if equipped) and

pump out the oil.

For easier draining, remove the engine

oil fill cap. Dispose of used oil properly.

NOTICE

• Prevent dirt and debris from

contaminating engine oil. Carefully

clean the dipstick and the surrounding

area before removing the dipstick.

• Always be environmentally

responsible.

3. Remove the engine oil filter (Figure 2)

with a filter wrench (turn

counterclockwise).

4. Install a new filter element and tighten

by hand until the seal touches the

housing.

5. Turn filter an additional 3/4 turn

clockwise with a box wrench. Tighten to

20 to 24 N·m (177 to 212 in.-lb).

6. Fill with new engine oil. See Adding

Engine Oil on page 39.

NOTICE

Never mix different types of engine oil.

This may adversely affect the lubricating

properties of the engine oil.

Never overfill. Overfilling may result in

white exhaust smoke, engine overspeed

or internal damage.

7. Perform a trial run and check for oil

leaks.

8. Approximately 10 minutes after

stopping the engine, remove the oil

dipstick and check the oil level. Add oil

if the level is too low.
