How To Change the Oil for your Ford Diesel Truck

In order to properly maintain your Ford diesel truck, you’ll need to engage in regular maintenance at home. One of the best ways to keep the engine in your vehicle working as it should is to check and change the oil regularly. Diesel trucks, like all other vehicles on the road, require fresh oil in order to keep the engine lubricated so that it doesn’t overheat or suffer from other damage as well. It’s a good idea to change the oil in your truck about every 3000 miles or so. You can save time, money and effort by doing this at home instead of taking your truck into a service station, and this is a great way to learn about the inner workings of your vehicle as well. The entire process, outlined below in a step by step guide, should take about an hour to complete.

Step 1 — Gather the Materials

You’ll need the following tools and materials in order to change the oil in your Ford diesel truck:

  • New oil filter
  • New oil packages (several quarts)
  • Jack stand set
  • Oil drain pan
  • New gasket system (optional)
  • Wrenches
  • Funnel, newspapers, paper towels

Step 2 — Prep the Truck

Wait until the truck has been turned off for several hours before you begin to work. You want the engine to be almost entirely cool, but not completely. Mount the front end of the truck up on the jack stand and ensure that you’ll be able to access the base of the truck and the underside. Open up the hood and keep it propped open with a propping bar. Lay out a set of newspapers below the front portion of the truck to allow for the oil that might spill as you work.

Step 3 — Drain the Old Oil

Next, you’ll need to locate the oil container and place your oil drain pan beneath it. Find the drain plug at the base of the container and remove it by unscrewing it. As soon as you begin to unscrew it, the oil will begin to flow out, so you’ll need to be prepared to catch it with the pan. Leave the pan in place for several minutes until all of the oil has drained out. When it has completely cleared, use a paper towel set to clean up the old oil from around the drain plug and inside the container.

Step 4 — Check and Change the Filter and Gasket

Unscrew the filter with a wrench or by hand, then let it drain out into the drain pan as well. Examine it for signs of corrosion and other damage. If it displays these signs, it’s a good idea to change the oil filter on your truck and replace it with a new one. Otherwise, put it back in place on the oil system. You can do the same for the gasket system, if you wish.

Step 5 — Replace the Oil

Close up the drain plug at the base of the container and put the end of the funnel into the top of the container. Carefully pour in a new set of oil into the truck. You’ll want to check the owner’s manual to see exactly how many quarts of oil that you should use, as well as any specifications for which type of oil will work best. When the oil has fully drained into the truck, close up the container and the hood and remove the vehicle from the jack stands.

Before you turn the engine on once again, it’s important that you check on the oil levels one last time. Use a dipstick to manually check the level and adjust the amount of oil in the truck as necessary until you get a good reading.

All of the different tools and materials that you’ll need to complete this project are available at your local hardware store or at a nearby auto body repair shop.
