Periodic Maintenance Procedures

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 and filter

change is performed as scheduled.

Note: The oil drain plug may be in another

location if an optional oil pan is used.

Drain the engine oil as follows:

1. Make sure the engine is level.

2. Start the engine and bring it up to operating

temperature.

3. Stop the engine.

4. Remove the oil filler cap (Figure 5-1, (1)) to

vent the engine crankcase and allow the engine

oil to drain more easily.

5. Position a container under the engine to collect

waste oil.

Figure 5-1

6. Remove the oil drain plug (Figure 5-2, (1)).

Allow oil to drain.

7. After all oil has been drained from the engine,

reinstall the oil drain plug (Figure 5-2, (1)) and

tighten to 39.8 - 47.0 ft·lb (53.9 - 63.7 N·m, 5.5 -

6.5 kgf·m).

8. Dispose of used oil properly.

Remove the engine oil filter as follows:

1. Turn the engine oil filter (Figure 5-2, (2))

counterclockwise (Figure 5-2, (4)) using a filter

wrench.

Figure 5-2

2. Clean the engine oil filter mounting face.

3. Lightly coat the gasket on the new oil filter with

clean engine oil. Install the new engine oil filter

manually by turning it clockwise

(Figure 5-2, (3)) until it contacts the mounting

surface. Tighten to 14 - 17 ft·lb (19.6 - 23.5 N·m,

2.0 - 2.4 kgf·m or one additional turn using the

filter wrench.

4. Add new engine oil to the engine as specified in

Adding Engine Oil on page 4-14.

Check and Adjust Cooling Fan V-Belt

The V-belt will slip if it does not have the proper

tension. This will prevent the alternator from

generating sufficient power. Also, the engine will

overheat due to the engine coolant pump pulley

slipping.
