HIGH PRESSURE SYSTEM: GENERAL INFORMATION
The heart of GM's 5.7L, 6.2L, and 6.5 diesel engines is the high-pressure system which delivers fuel to the combustion chambers.
FLUID LEVEL CHECKS
The high-pressure system consists of the injection pump, the injection nozzles and the metal lines between the pump and the nozzles.
The high-pressure system sounds pretty simple in principle, but in fact it's anything but simple.
The high-pressure system performs many functions, many more than a carburetor or fuel injection system on a gasoline-powered vehicle.
Not only must it meter - in accordance with the load and speed of the engine - the quantity of fuel required for each cycle of the engine.
It must also develop the high pressure necessary to inject fuel into each cylinder at a precisely determined instant in its operation cycle (firing order).
And it must control the rate at which the fuel is injected, atomize and distribute the fuel throughout the combustion chamber, and start and end each injection cycle abruptly.
Obviously, the high-pressure system is fairly complex.
NOTE: The following are fluid level checks to be done on a 250 mile or weekly basis. Additional fluid level checks can be found in specific maintenance procedures which follow.
Regardless of intervals, be alert to fluid leaks under the vehicle which would indicate a fault to be corrected immediately.
Fluids are an essential part of the lubrication and cooling systems. Because the fluids gradually become depleted and/or contaminated during normal operation of the vehicle, they must be periodically replenished.
See Recommended lubricants and fluids at the beginning of this Chapter before adding fluid to any of the following components. Note: The vehicle must be on level ground when fluid levels are checked.
