To make draining the oil faster we recommend removing the oil filter first. The oil filter is located on the left hand side of the engine.
Use a 27mm oil filter wrench to remove the cap of the oil filter housing.
Remove the cap. The oil filter will likely be stuck in the housing. The oil filter pulls straight up and out, though it can be a bit hard to pull out.
With the oil filter removed, it is time to remove the old oil. There are two ways to do this – drain from the bottom or extract from the top.
Top side extracting can save time and make the job cleaner overall, especially if you are doing oil changes in your driveway. We use and recommend eXtoil oil extractors (IDParts, Extoil Direct). To extract your LWM’s oil, remove the oil dipstick and insert the extractor tube down the oil dipstick tube. See our Guide to Oil Extractors for more information.
If you are going to drain from the bottom of the drain pan, the oil pan is located near the rear of the engine.
The oil drain plug is a 15mm socket size. Position your oil drain pan or collecting tool before removing the oil drain plug.
The oil drain plug uses custom molded o-ring rather than a crush washer. You may need to clean off the drain plug to locate the seal. Remove the seal and replace with a new one.
Once the oil has finished draining reinstall the oil drain plug and tighten to 18 ft/lbs. This is a VERY low torque, but remember that the seal is being made by a elastomer o-ring, not a crush washer, so there is no reason to really torque the drain plug down.
Good quality oil filters will come with replacement o-rings for the oil filter housings. This OE unit from UFI comes with a large blue o-ring, which matches the factory o-ring perfectly.
Retrieve the oil filter cap and remove the large o-ring above the threaded section.
Install new o-ring, be sure that you have it located in the correct groove or you may damage the o-ring and cause the cap to leak
The new oil filter should be clipped into the oil filter cap before installing it in the housing.
Before installing the filter, lubricate all three o-rings (the one on the cap and the two on the filter) with oil. This prevents the o-rings from binding when being installed.
Reinstall the new oil filter and cap into the housing. Once again, this is a LOW TORQUE specification, as noted on the cap, tighten to 25nm, which is about 18 ft/lbs.
Finally, refill the engine with oil. Be sure to use an oil that carries the dexos2 approval. This oil, Rowe SYNT RS DLS shows the approval on the front label.
This engine takes just under 6 quarts, so fill first with 5 quarts and then check the oil level using the oil dipstick. You want to shoot for the middle of the hatch-marked area on the end of the dipstick.
Once the oil is refilled to the proper level go inside the truck to reset the oil life indicator. Go to information, then scroll to oil life, then press the right arrow and it will offer you the option to reset. Select and confirm. Now you’re good to go for another 10,000 miles!
