How to Change Injectors on a 6 0 Ford Engine

Ford began producing an eight-cylinder 6.0-liter diesel engine in 2003 that appeared in heavy Ford trucks until 2008. This is a diesel engine with fuel injection that is typically turbocharged. It is most common in Ford Super Duty trucks, and is the standard engine in the 2007 Ford F350 Super Duty with four-wheel drive. The fuel injectors for this engine are part of the fuel rail assembly, which you must remove to replace the fuel injectors.

Instructions

1

Remove the mounting bolts for the valve cover with a socket wrench and disconnect the valve cover. Unplug the wiring harnesses from the fuel injectors, and disconnect the crankcase-to-head tube assembly from the engine.

2

Remove the mounting bolts for the oil rail with a socket wrench and disconnect the oil rail. Push the electrical connector for the fuel injector out of the rocker arm carrier with a small pry tool. Plug the oil drain holes next to the glow plugs with clean shop rags.

3

Disconnect the mounting bolt for the fuel injector with a socket wrench and release the hold-down clamp on the fuel injector. Remove the fuel injectors from the fuel rail with a Snap-On SDMT440 Torx tool so that you dont damage the fuel injectors plastic housing. Remove the shop rags from the oil drain holes. Discard the O-rings and copper washers on the fuel injectors.

4

Mount the new O-rings and copper washers on the fuel injectors. Lubricate the fuel injectors with engine oil and install the fuel injectors to the fuel rail. Attach the hold-down clamps for the fuel injectors and tighten the mounting bolt 24 ft. lbs. with a torque wrench. Connect the electrical connector to the rocker arm carrier and coat the upper O-rings on the fuel injectors with engine oil.

5

Place the oil rail on the fuel injectors so that the single ball tubes on the oil rail engage the lead angle of the fuel injectors. Insert a guide bolt into each end of the oil rail and a guide bolt in the middle of the oil rail to temporarily hold it in place. Push the oil rail into the fuel injectors so the mounting feet of the oil rail are flush with their mounting surface on the engine block. Install mounting bolts for the oil rail into the six available holes and replace the three guide bolts with mounting bolts. Tighten the nine mounting bolts to 10 ft. lbs with a torque wrench.

6

Connect the crankcase-to-head tube assembly and tighten the mounting bolts to 60 ft. lbs. with a torque wrench. Attach the electrical connectors to the fuel injectors and install the valve covers.
