See Figures 1 and 2
A high quality heavy-duty detergent oil having the proper viscosity for prevailing temperatures and a minimum SG/CC service rating should be used in your vehicle. A high quality SG/CC rated oil should be used for heavy duty service or turbocharged equipped engines. The SG/CC and SG/CD rated oil contain sufficient chemical additives to provide maximum engine protection.
Pick an oil with the viscosity that matches the anticipated temperature of the region your vehicle will be operated in before the next oil change. A chart is provided to help you with your selection. Choose the oil viscosity for the lowest expected temperature and you will be assured of easy cold weather starting and sufficient engine protection.
OIL LEVEL CHECK
See Figures 3, 4, 5, 6 and 7
The engine oil level is checked with the dipstick which is located on the radiator side of the engine.
The oil should be checked before the engine is started or five minutes after the engine has shut OFF. This gives the oil time to drain back to the oil pan and prevents an inaccurate oil level reading.
Remove the dipstick from the tube, wipe it clean, and insert it back into the tube. Remove it again and observe the oil level. It should be maintained within the full range on the dipstick.
Do not overfill the crankcase. This will cause oil aeration and loss of oil pressure.
OIL AND FILTER CHANGE
See Figures 8, 9, 10 and 11
The recommended mileage figures for oil and filter changes are 7500 miles or 12 months whichever comes first, assuming normal driving conditions. If your vehicle is being used under dusty conditions, frequent trailer pulling, excessive idling, or stop and go driving, it is recommended to change the oil and filter at 3000 miles.
Improper disposing of all lubricants (engine, trans., and differential), can result in environmental problems. Contact your local dealerships or service stations for advice on proper disposal.
Always drain the oil after the engine has been running long enough to bring it to operating temperature. Hot oil will flow easier and more contaminants will be removed along with the oil than if it were drained cold.
Chrysler recommends changing both the oil and filter during the first oil change and the filter every other oil change thereafter. For the small price of an oil filter, it's cheap insurance to replace the filter at every oil change. One of the larger filter manufacturers points out in its advertisements that not changing the filter leaves as much as one quart of dirty oil in the engine. This claim is true and should be kept in mind when changing your oil.
- Run the engine until it reaches normal operating temperature.
- Raise the front of the vehicle and support on jackstands, remove the shield if it will cause interference.
- Slide a drain pan of at least 6 quarts capacity under the oil pan.
- Loosen the drain plug. It is located in the lowest point of the oil pan. Turn the plug out by hand. By keeping an inward pressure on the plug as you unscrew it, oil won't escape past the threads and you can remove it without being burned by hot oil.
- Allow the oil to drain completely and then install the drain plug. Don't over tighten the plug, it will result in stripped threads.
- Using a strap wrench, remove the oil filter. Keep in mind that it's holding about one quart of dirty, hot oil.
- Empty the old filter into the drain pan and dispose of the filter.
- Using a clean rag, wipe off the filter adapter on the engine block. Be sure that the rag doesn't leave any lint which could clog an oil passage.
- Coat the rubber gasket on the filter with fresh oil. Spin it onto the engine by hand; when the gasket touches the adapter surface give it another 1 / 2 - 3 / 4 turn. No more, or you'll squash the gasket and it may leak.
- Remove the jackstands and carefully lower the vehicle.
- Refill the engine with the correct amount of fresh oil. See the Capacities Chart in this section.
Refill the engine crankcase slowly, checking the level often. You can always add a little more oil, but removing some at this point would be a bother.
- Run the engine at idle for approximately one minute. Shut the engine OFF . Wait a few minutes and recheck oil level. Add oil, as necessary to bring the level up to Fill .
