ENGINE OIL CHANGE
WARNING: NEW OR USED ENGINE OIL CAN BE
IRRITATING TO THE SKIN. AVOID PROLONGED OR
REPEATED SKIN CONTACT WITH ENGINE OIL.
CONTAMINANTS IN USED ENGINE OIL, CAUSED BY
INTERNAL COMBUSTION, CAN BE HAZARDOUS TO
YOUR HEALTH. THOROUGHLY WASH EXPOSED
SKIN WITH SOAP AND WATER. DO NOT WASH
SKIN WITH GASOLINE, DIESEL FUEL, THINNER, OR
SOLVENTS, HEALTH PROBLEMS CAN RESULT. DO
NOT POLLUTE, DISPOSE OF USED ENGINE OIL
PROPERLY. CONTACT YOUR DEALER OR GOVERN-
MENT AGENCY FOR LOCATION OF COLLECTION
CENTER IN YOUR AREA.
Run engine until achieving normal operating tem-
perature.
(1) Position the vehicle on a level surface and turn
engine off.
(2) Remove oil fill cap.
(3) Hoist vehicle. Refer to Hoisting and Jacking
Recommendations.
(4) Place a suitable drain pan under crankcase
drain.
(5) Remove drain plug from crankcase and allow
oil to drain into pan (Fig. 5). Inspect drain plug
threads for stretching or other damage. Replace
drain plug if damaged.
(6) Install drain plug in crankcase.
(7) Lower vehicle and fill crankcase with specified
type and amount of engine oil.
(8) Install oil fill cap.
(9) Start engine and inspect for leaks.
(10) Stop engine and inspect oil level.
ENGINE OIL
ENGINE OIL QUALITY
Use only oils conforming to API (American Petro-
leum Institute) quality SG/CD, or CCMC G4. Use
only Diesel engine oil meeting standardMIL-2104C
or API service classificationSG/CD or CCMM PD1.
OIL VISCOSITY
Grade 15W-40 is recommended for temperatures
between +35ÉC to ±10ÉC (95ÉF to 14ÉF). Low viscosity
oils must have the proper API quality or the CCMC
G5 designation. Low viscosity oils are preferred when
minimum temperatures consistently fall below ±12ÉC
(10ÉF).
ENGINE OIL FILTER CHANGE
(1) Position a drain pan under the oil filter.
(2) Using a suitable oil filter wrench loosen filter.
(3) Rotate the oil filter counterclockwise to remove
it from the oil filter base (Fig. 6).
(4) When filter separates from base, tip gasket end
upward to minimize oil spill. Remove filter from vehi-
cle.
(5) With a cloth, wipe clean the gasket sealing sur-
face of oil and grime.
OIL FILTER INSTALLATION
(1) Lightly lubricate oil filter gasket with engine
oil.
(2) Thread filter onto the base. When gasket
makes contact with sealing surface, hand tighten fil-
ter one full turn, do not over tighten.
