FREQUENCY OF ENGINE OIL AND FILTER CHANGES

ENGINE OIL

Road conditions as well as your kind of driving affect the interval at which your oil should be changed. Check the following to determine if any apply to you:

²Frequent short trip driving less than 8 kilometers (5 miles)

²Frequent driving in dusty conditions

²Frequent trailer towing

²Extensive idling (such as vehicle operation in stop and go traffic)

²More than 50% of your driving is at sustained high speeds during hot weather, above 32°C (90°F)

If any of these apply to you then change your engine oil every 4 800 kilometers (3,000 miles) or 3 months, whichever comes first.

If none of these apply to you then change your oil every 12 000 kilometers (7,500 miles) or 6 months, whichever comes first.

If none of these apply and the vehicle is in commercial type service such as, Police, Taxi or Limousine and principally used for highway driving of 40 kilometers (25 miles) or more between stations, the engine oil should be changed every 8 000 kilometers (5,000 miles) or 6 months, whichever comes first.

OIL FILTER

The engine oil filter should be replaced with a new filter at every second oil change.

ENGINE OIL

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 GOVERNMENT AGENCY FOR LOCATION OF COLLECTION CENTER IN YOUR AREA..

BREAK-IN PERIOD

CAUTION: Wide open throttle operation in low gears, before engine break-in period is complete, can damage engine.

On a Chrysler Corporation vehicle an extended break-in period is not required. Driving speeds of not over 80-90 km/h (50-55 mph) for the first 100 km (60 miles) is recommended. Hard acceleration and high engine rpm in lower gears should be avoided.

SELECTING ENGINE OIL

CAUTION: Do not use non-detergent or straight mineral oil when adding or changing crankcase lubricant. Engine or Turbocharger failure can result.

The factory fill engine oil is a high quality, energy conserving, crankcase lubricant. The Recommended SAE Viscosity Grades chart defines the viscosity grades that must be used based on temperature in the region where vehicle is operated (Fig. 1) and optional equipment.

Chrysler Corporation recommends that Mopart motor oil, or equivalent, be used when adding or changing crankcase lubricant. The API symbol (Fig. 2) on the container indicates the viscosity grade, quality and fuel economy ratings of the lubricant it contains. Use ENERGY CONSERVING II motor oil with API SERVICE SG or SG/CD classification.

²SG service engine oil is a high quality crankcase lubricant designed for use in all naturally aspirated engines. If SG service engine oil is used in turbocharged engine, change engine oil at every 4 800 km (3,000 miles) or three months.

²SG/CD service engine oil is a high quality crankcase lubricant designed for use in most naturally aspirated and turbocharged gasoline or diesel engines.

ENGINE OIL ADDITIVES

Chrysler Corporation recommends that Mopart Engine Oil Supplement or equivalent be used when friction and corrosion reducing materials added to the crankcase lubricant is desired.

CAUTION: Do not overfill crankcase with engine oil, oil foaming and oil pressure loss can result.

Inspect engine oil level approximately every 800 kilometers (500 miles). Position vehicle on level surface. With engine OFF, allow enough time for oil to settle to bottom of crankcase, remove engine oil level indicator (dipstick) and wipe clean. Install dipstick and verify it is seated in the tube. Remove dipstick, with handle above tip, take oil level reading (Fig. 3). Add oil only if level is below MIN or ADD mark on dipstick.

ENGINE OIL CHANGE

Change engine oil at mileage and time intervals described in Lubrication and Maintenance Schedules. Position the vehicle on a level surface. Hoist and support vehicle on safety stands. Refer to Hoisting and Jacking Recommendations in this group. Place a suitable 3.8 liter (4 qt.) drain pan under crankcase drain. Remove drain plug from crankcase. Inspect drain plug threads for stretching or other damage. Replace drain plug and gasket if damaged. Install drain plug in crankcase. Lower vehicle and fill crankcase with specified type and amount of engine oil described in this section. Start engine and inspect for leaks. Stop engine and inspect oil level.

ENGINE OIL FILTER

SELECTING OIL FILTER

Chrysler Corporation recommends a Mopart or equivalent oil filter be used when replacement is required. A replacement filter must be designed to withstand 1756 kPa (256 psi) of internal pressure.

OIL FILTER REPLACEMENT

Position a drain pan under the oil filter. Using a suitable oil filter wrench (Fig. 4) loosen filter. When filter separates from adapter nipple, tip gasket end upward to minimize oil spill. Remove filter from vehicle. With a wiping cloth, clean the gasket sealing surface (Fig. 5) of oil and grime. Wipe off oil residue from below oil filter adapter.

Fig. 4 Remove Oil Filter

Fig. 5 Install Oil Filter

TO INSTALL NEW OIL FILTER:

Lightly lubricate oil filter gasket with engine oil or chassis grease. Thread filter onto adapter nipple. When gasket makes contact with sealing surface, tighten filter one full turn. If necessary use a filter wrench, do not over tighten. Add oil, verify crankcase oil level and start engine. Inspect for oil leaks.

ENGINE COOLING SYSTEM

WARNINGS AND PRECAUTIONS

WARNING: ANTIFREEZE IS AN ETHYLENE GLYCOL BASE COOLANT AND IS HARMFUL IF SWALLOWED OR INHALED. IF SWALLOWED, DRINK TWO GLASSES OF WATER AND INDUCE VOMITING. IF INHALED, MOVE TO FRESH AIR AREA. SEEK MEDICAL ATTENTION IMMEDIATELY. DO NOT STORE IN OPEN OR UNMARKED CONTAINERS. WASH SKIN AND CLOTHING THOROUGHLY AFTER COMING IN CONTACT WITH ETHYLENE GLYCOL. KEEP OUT OF REACH OF CHILDREN.

DISPOSE OF GLYCOL BASE COOLANT PROPERLY, CONTACT YOUR DEALER OR GOVERNMENT AGENCY FOR LOCATION OF COLLECTION CENTER IN YOUR AREA.

DO NOT OPEN A COOLING SYSTEM WHEN THE ENGINE IS AT RUNNING TEMPERATURE, PERSONAL INJURY CAN RESULT.

AVOID RADIATOR COOLING FAN WHEN ENGINE COMPARTMENT RELATED SERVICE IS PERFORMED, PERSONAL INJURY CAN RESULT.

CAUTION: Do not use straight antifreeze as engine coolant, inadequate engine running temperatures can result.

Do not operate vehicle without proper concentration of recommended ethylene glycol coolant, high running temperatures and cooling system corrosion can result.

The engine cooling system will develop internal pressure of 97 to 123 kPa (14 to 18 psi) at normal operating temperature. Allow the vehicle approximately one half hour to cool off before opening the cooling system. As an indicator of pressure, squeeze the

upper radiator hose between index finger and thumb. If it collapses with little effort the system would have low internal pressure and should be safe to open to the first safety notch of the radiator cap. Refer to Group 7, Cooling System.

COOLING SYSTEM INSPECTION

Coolant level (Fig. 6) should be inspected when other engine compartment service is performed or when coolant leak is suspected. Coolant recovery tank level should read between the MIN and MAX marks, located on the side of recovery tank, when the engine is at normal operating temperature. Normal coolant level maintenance does not require the removal of radiator cap. Cooling system freeze protection should be tested at the onset of the winter season or every 12 months. Service is required if coolant is low, contaminated, rusty or freeze protection is inadequate. To properly test cooling system, see Group 7, Cooling System.

The cooling system factory fill is a mixture of 50% Glycol based antifreeze and 50% water. Using a suitable hydrometer, measure antifreeze concentration in the radiator when the engine is cool. If the cooling system has recently been serviced, allow coolant to circulate for at least 20 minutes before taking hydrometer reading. Properly mixed coolant will pro-
