OIL LEVEL CHECK
See Figures 1, 2, 3 and 4
- Make sure the car is parked on level ground.
- When checking the oil level, it is best for the engine to be at normal operating temperature, although checking the oil immediately after stopping will lead to a false reading. Wait a few minutes after turning off the engine to allow the oil to drain back into the crankcase.
- Open the hood and locate the dipstick which will be in a guide tube mounted in the engine block. Pull the dipstick from its tube, wipe it clean (using a clean, lint free rag) and then reinsert it.
- The oil dipstick has two marks to indicate the minimum (MIN.) and maximum (MAX) oil level. If the oil is at or below the "MIN" mark on the dipstick, add oil of the proper viscosity through the capped opening in the top of the camshaft (valve) cover. See the oil and fuel recommendations listed earlier in this section for the proper viscosity and rating of oil to use. The oil level should be maintained in the safety margin, neither going above the "MAX" mark or below the "MIN" mark.
- Insert the dipstick and check the oil level again after adding any oil. Approximately one quart of oil will raise the level from the MIN mark to the MAX mark. Be sure not to overfill the crankcase and waste the oil. Excess oil will generally be consumed at an accelerated rate.
OIL & FILTER CHANGE
See Figures 5, 6, 7, 8 and 9
The manufacturer's recommended oil change interval is 7,500 miles (12,000 km) under normal operating conditions. We recommend and oil change interval of 3,000-3,500 miles (4,800-5,600 km) under normal conditions; more frequently under severe conditions such as when the average trip is less than 4 miles (6 km), then engine is operated for extended periods at idle or low-speeds, when towing a trailer or operating in dusty areas.
In addition, we recommend that the filter be replaced EVERY time the oil is changed.
- Run the engine until it reaches normal operating temperature.
- Raise the front of the vehicle and support it safely using a suitable pair of jackstands.
- Slide a drain pan of a least 6 quarts capacity under the oil pan. Wipe the drain plug and surrounding area clean using an old rag.
- Loosen the drain plug using a ratchet, short extension and socket or a box-wrench. Turn the plug out by hand, using a rag to shield your fingers from the hot oil. 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.
If the drain plug is equipped with a removable washer or gasket, check its condition and replace, if necessary, to provide a leakproof seal.
- Quickly withdraw the plug and move your hands out of the way. Allow the oil to drain completely into the pan, then install and carefully tighten the drain plug to 26-32 ft. lbs. (35-45 Nm). Be careful not to overtighten the drain plug, otherwise you'll be buying a new pan or a replacement plug for stripped threads.
Although some manufacturers recommend changing the oil filter every other oil change, we recommend the filter be changed each time you change your oil. The old filter will contain up to a quart of dirty oil, which will contaminate the clean oil. Also, the benefit of clean oil is quickly lost if the old filter is clogged. The added protection for your engine far outweighs the few dollars saved by using an old filter.
- Move the drain pan under the oil filter. Use a strap-type or cap-type filter wrench to loosen and remove the oil filter from the engine block. Keep in mind that it's holding about one quart of hot, dirty oil.
Make sure the O-ring from the old oil filter is on the old oil filter. If a new oil filter is installed with the old O-ring stuck on the engine filter head, a severe oil leak will result. This, if not noticed, could result in engine damage. The quality of replacement filters vary widely. Only high quality filters should be used to assure most efficient service. Install only oil filters capable of withstanding a pressure of 256 psi.
Do NOT overtighten the oil filter.
Coat the O-ring on the top of the new oil filter lightly with clean engine oil. Thread the filter onto the oil filter head by hand. Tighten the oil filter as follows:
- For MD135737 filters: one full turn or 9-12 ft. lbs. (12-16 Nm)
- For MD136466 filters: 3 / 4 turn or 10-14 ft. lbs. (13-20 Nm).
- For M05281090: 3 / 4 turn or 15 ft. lbs. (20 Nm).
- Carefully lower the vehicle.
- Refill the engine with the correct amount of fresh oil. Please refer to the Capacities chart in this section.
- Check the oil level on the dipstick. It is normal for the level to be a bit above the full mark. Start the engine and allow it to idle for a few minutes.
- Shut off the engine and allow the oil to flow back to the crankcase for a minute, then recheck the oil level. Check around the filter and drain plug for any leaks, and correct as necessary.
