Industrial CN-5019-RM Fuel Injector Stock+ | 2003-2007 Ford F250/F350 6.0L Powerstroke

The 6.0L Power Stroke Diesel Engine utilizes a hydraulic injection system where high pressure engine oil is used to compress diesel fuel. The fuel injector is used to precisely control the delivery of the fuel into the combustion chamber. Following appropriate maintenance intervals and using the proper Motorcraft Original Equipment parts will ensure optimal injector durability.

INJECTOR QUALITY:

Internal components of this injector are designed with tolerances down to the thousandths of an inch. These precision tolerances are critical to ensure peak horsepower, torque and to meet stringent Federal emission standards. Extended oil change intervals and poor quality filters may cause fatigued or dirty oil to enter the injector, wearing down internal components. This can lead to poor cold starting performance, lack of power or even injector failure.

Normal and Special Operating Conditions:

Customers use Power Stroke Diesel engines for a variety of applications, creating a need for two distinct maintenance interval schedules. The first schedule, called“Normal Operating Conditions”, applies to most personal use vehicles. The second schedule, called “Special Operating Conditions”, applies to many commercial use applications, including:

Oil Change Intervals:

Under Normal Operating Conditions, oil and filter changes are specified every 7,500 miles (12,000 km). If the Special Operating Conditions schedule applies to your vehicle, oil and oil filter changes should be performed every 5,000 miles (8,000 km), three months or 200 hours of operation (whichever occurs first). For engines that experience high idle times, maintenance intervals should be based on engine hours as opposed to mileage (F-Series trucks built after 2004 are all equipped with hour meters).

Fuel System Maintenance Intervals:

Fuel filters are specified to be replaced at every other oil change. Under Special Operating Conditions, both fuel filters should be replaced every 10,000 miles (16,000 km), six months or 400 engine hours (whichever occurs first). Following the appropriate maintenance intervals will help ensure adequate fuel pressure. Figure 1 shows that diesel fuel acts not only as a lubricant for the injector, but also as a cushion, preventing metal on metal contact of the internal components. If adequate fuel pressure is not attained, the internal components can wear down, and lead to injector misfires or injector failure.
