There have been large advancements in diesel engines over the past 20 years, and with the addition of turbochargers, more horsepower and torque is available than ever before. Sometimes though, the turbo will need servicing, such as if a bearing spins or the turbo gets damaged. In this case, the project vehicle is a 2004 Ford F-250 with the Powerstroke diesel engine.
Pop the hood and locate the turbocharger on the engine. Place a drain pan on the floor below the turbo to catch any oil or fluid that may spill.
Unclip the air filter housing using your hands, then lift out the stock air filter. Unbolt the air filter housing from the engine and the turbocharger using the flathead screwdriver and the 3/8-inch ratchet and socket. Pull out the intake tubing so that it's out of the engine compartment.
Use the flathead screwdriver to remove the hose clamps that secure the engine vent and the radiator vent to the intake tubing. Unbolt the coolant reservoir from the engine bay and set it out of the way.
Unplug the wiring harnesses near the turbo. Unbolt the oil supply tube from the turbo using the 3/8-inch ratchet, extension and sockets. Unbolt the clamps on the turbo at the turbo outlet and the turbo inlet using the ratchet. Unbolt the turbo from the exhaust manifold, then lift it away from the engine.
