Steps
- Raise the truck and drain the oil
Park on level ground, chock the wheels, and raise the truck at approved points before supporting it on jack stands. Place a pan under the drain plug, remove the plug, and allow the oil to drain before reinstalling it to specification.
- Remove the oil filter
Move the pan below the filter and loosen it with a filter wrench. Wipe the mounting surface clean and verify the old gasket did not remain stuck to the engine.
- Install the replacement filter
Apply a thin film of fresh oil to the new filter gasket and thread the filter on squarely by hand. Tighten it according to the filter instructions without overtightening.
- Refill and check the oil level
Lower the truck and add the specified quantity of oil through a funnel, then reinstall the filler cap. Start the engine briefly, check around the filter and drain plug for leaks, shut it off, and confirm the settled dipstick level is in range.
Check your vehicle’s repair manual for exact specifications and fit.
