However, changes that are more frequent may
be required when the engine is subject to high
levels of contamination and/or overheating.
Change intervals may be decreased or gradually
increased with experience on specific lubricants
until the most practical service condition has
been established. Always refer to the lubricant
manufacturer's recommendations (analysis of
drained oil can be helpful).
CAUTION
Do not use solvents to dilute the engine oil
when draining. Dilution of fresh oil can occur
which may be detrimental to the engine.
Change engine oil with the vehicle on a flat and
level surface and with the parking brake applied.
It is best to drain the oil when the engine is still
warm.
1. From under the vehicle, remove the engine
drain plug on the oil pan. Allow oil to drain
(Fig. 22).
WARNING
Hot engine oil can cause serious burns. Wear
coveralls with sleeves pulled down and gloves
to protect hands.
2. Reinstall the drain plug.
3. Remove the spin-on filter cartridge using a
½" drive socket wrench and extension.
4. Dispose of the used oil and filter in an
environmentally responsible manner in
accordance with state and/or federal (EPA)
recommendations.

5. Clean the filter adapter with a clean rag.
6. Lightly coat the filter gasket (seal) with clean
engine oil.
7. Install the new filter on the adapter and
tighten manually until the gasket touches the
mounting adapter head. Tighten full-flow
filters an additional two-thirds of a turn
manually. Then, manually tighten bypass
filter one full turn.
CAUTION
Overtightening may distort or crack the filter
adapter.
8. Remove the engine-oil filler cap and pour oil
in the engine until it reaches the "FULL" mark
on the dipstick (Fig. 20).
9. Start and run the engine for a short period
and check for leaks. After any leaks have
been corrected, stop the engine long enough
for oil from various parts of the engine to
drain back to the crankcase (approximately
20 minutes).
10. Add oil as required to bring the level within
the safe range on the dipstick (Fig. 20).
MAINTENANCE
Engine oil temperature should be checked
every 25,000 miles (40 000 km) to determine
oil cooler efficiency. This check should be
made by inserting a steel jacketed
thermometer in the dipstick opening,
immediately after stopping a hot, loaded
engine. If the oil temperature exceeds the
coolant temperature by more than 60 °F (33
°C), the oil cooler may be clogged.
