Replacing a radiator can be needed if a leaked or clogged coolant tube causes damaged in the radiator. Ford F-series truck radiators need to be replaced if they are leaking or no longer working properly and, with the correct tools and instructions, this can be done at home.
Gather Tools: Before Ford F-series truck radiators can be replaced, you need to have the right tools and materials. You first need to get a new radiator that is designed for the engine size. Engines of different sizes have different cooling needs, so be sure to choose the right one. In addition to the radiator, you need a drain pan, new coolant, and replacement hoses if the old hoses are brittle or cracked, along with new hose clamps. You also need a flathead and Philips screwdriver, 8mm socket wrench, 10mm socket wrench, pliers, flashlight, ratchet and extension, and 16mm combination wrench.
Remove Old Radiator: Be sure the truck is cool before you begin to remove the radiator. If your truck is still warm and the coolant is hot, it can cause burns. It’s best if you remove the plastic to give better access to the coolant drain. Once you have removed the plastic cover, be sure to keep it nearby, since you will need to reinstall it later. Then remove the radiator reservoir cap, in order to drain the coolant easier. Position the drain pan below the drain stopcock, which is on the right side of the truck. You will then drain the coolant.
In an effort to get better access to the radiator, remove the air intake ducting before removing the fan shroud. Once that is done, remove the fan shroud and then it’s time to remove the actual radiator. When removing the radiator, you can hold the base of the hose connection with pliers and use a wrench to help loosen it. When you are removing the remaining coolant hoses, you could have more access from below the truck. Also, depending on the position of the clamp, you could have to remove the coolant reservoir to be able to remove the hose clamp properly.
Install New Radiator: Be sure you remove all the plastic plugs and caps from the new radiator. You may also want to run water through the radiator to make sure that there isn’t any debris or dirt inside, but be sure to drain it fully afterward. If the new radiator doesn’t come with a new plastic stopcock, you will want to install the one from the old radiator. Be sure to fill the radiator with fresh coolant and take the time to check that there aren’t any leaks. You may also want to check the transmission fluid, since some could have gotten lost when reinstalling the transmission cooler lines.
