OIL LEVEL CHECK
See Figures 1, 2 and 3
The engine oil level should be checked frequently, particularly in older or high mileage engines. A good time to do so is at each refueling stop. Be sure that the vehicle is parked on a level surface with the engine off. Also, allow a few minutes after turning off the engine for the oil to drain into the pan, or an inaccurate reading will result.
- Open the hood and remove the engine oil dipstick.
- Wipe the dipstick with a clean, lint-free rag and reinsert it. Be sure to insert it all the way.
- Pull out the dipstick and note the oil level. It should be between the SAFE (MAX) mark and the ADD (MIN) mark.
- If the level is below the lower mark, replace the dipstick and add fresh oil to bring the level within the proper range. Do not overfill.
- Recheck the oil level and close the hood.
Use a multi-grade oil with API classification SG.
OIL AND FILTER CHANGE
See Figures 4, 5, 6, 7 and 8
The engine oil and oil filter should be changed at the same time, at the recommended intervals on the maintenance schedule chart. Because of their operating characteristics, it is extremely important to change the oil and oil filter on all 4-cylinder, turbocharged vehicles at 3,000 mile intervals.
- Run the engine to normal operating temperature.
- After the engine has reached operating temperature, shut it off, firmly apply the parking brake, and block the wheels.
- Raise and safely support the front end on jackstands.
- Place a drip pan beneath the oil pan and remove the drain plug. The oil could be very hot! Protect yourself by using rubber gloves if necessary.
- Allow the engine to drain thoroughly.
On some V8 engines a dual sump oil pan was used. When changing the oil, both drain plugs (front and side) must be removed. Failure to remove both plugs can lead to incomplete drainage and an incorrect oil level reading.
- When the oil has completely drained, clean the threads of the plug and coat them with non-hardening sealer or Teflon® tape and install the plug. Tighten it snugly.
The threads in the oil pan are easily stripped! Do not overtighten the plug!
- Place the drip pan beneath the oil filter.
- Using an oil filter wrench, turn the filter counterclockwise to remove it. The oil could be very hot! Protect yourself by using rubber gloves if necessary.
- Wipe the contact surface of the new filter clean and coat the rubber gasket with clean engine oil.
- Clean the mating surface of the adapter on the block.
- Screw the new filter into position on the block using hand pressure only. Do not use a strap wrench to install the filter! Then hand-tighten the filter 1 / 2 - 3 / 4 additional turn.
- Fill the crankcase with the proper amount of oil. Check the oil level prior to starting the engine.
- Start the engine and check for leaks.
Certain operating conditions may warrant more frequent oil changes. If the vehicle is used for short trips, where the engine does not have a chance to fully warm up before it is shut off, water condensation and low temperature deposits may make it necessary to change the oil sooner. If the vehicle is used mostly in stop-and-go traffic, corrosive acids and high temperature deposits may necessitate shorter oil changing intervals. The shorter intervals also apply to industrial or rural areas where high concentrations of dust and other airborne particulate matter contaminate the oil. Finally, if the car is used for towing trailers, a severe load is placed on the engine causing the oil to thin out sooner, necessitating shorter oil changing intervals.
