  2. Prepare the Truck: Park your truck on level ground and engage the parking brake. This will ensure stability throughout the oil change process.

  3. Locate the Oil Filter and Drain Plug: On the passenger side of the truck, you’ll find the oil filter and drain plug. Both are easily accessible, allowing for a straightforward oil change.

  4. Drain the Oil: Unscrew the drain plug to allow the old oil to flow into the drain pan. Ensure that the pan is large enough to hold all the oil.

  5. Remove the Old Oil Filter: Once the oil has finished draining, remove the old oil filter. You may need an oil filter wrench to loosen it. Allow any remaining oil to drain from the filter.

  6. Install the New Oil Filter: Before installing the new oil filter, prepare it by applying a dab of thread sealant. This will ensure a secure fit. Fill the new oil filter with oil, using a funnel to avoid spills.

  7. Replace the Drain Plug: Install a new drain plug washer on the drain plug before screwing it back into place. Ensure it is tightened securely.

  8. Add New Oil: Open the oil fill cap, typically located on the top of the engine. Using a funnel, pour the recommended amount of new oil into the engine. Check the owner’s manual for the exact specifications.

  9. Start the Engine: Once you’ve added the new oil, start the engine and let it run for about a minute. This will circulate the oil throughout the engine.

  10. Check the Oil Level: Turn off the engine and wait for a few minutes to allow the oil to settle. Use the dipstick to check the oil level and add more if necessary.
