Dodge Diesel Services



Diesel Fuel System service


Cummins 5.9L, 6.7L

During this two-part service we will completely isolate the diesel fuel system and run a highly concentrated cleaning solvent solution through the engine fuel system that removes deposits in the fuel injection pump, fuel lines, and fuel injectors. It also cleans deposit buildup in the combustion chamber and turbo charger. In addition we will use a fuel additive that will lubricate and restore internal fuel injection moving parts. This service will dramatically increase the life of your expensive diesel fuel system components.

We recommend this service at 60k miles and since a Fuel filter replacement is required we suggest scheduling this service at your fuel filter replacement interval.

 

Induction system service


Cummins 6.7L

Removes carbon buildup in the intake and exhaust recirculation passages maintaining proper airflow through the engine. Cleaning carbon buildup during service helps to prolong the EGR (Exhaust Gas Recirculation) Valve life, and removes internal sludge deposits. It also helps to prevent carbon from building up in the turbo, intake and exhaust valves Increasing engine performance, efficiency and fuel mileage. Ultimately saving you thousands in costly diesel engine repairs.

We recommend this service be performed at 30k intervals for normal use vehicles, and since a Lube, Oil, Filter change is necessary after the induction system service is performed we suggest scheduling this service at your oil change interval.

 

Turbocharger System Service


Cummins 6.7L

This service includes installing a special jet on the exhaust side of the turbo that will allow us to inject highly concentrated turbocharger cleaning solvent into the exhaust side of the turbo removing carbon and rust deposits restoring the factory vein movement.

 



Dodge Common Failures and Suggested Upgrades

Timing Cover Dowel Pin Upgrade (KDP)


Cummins 5.9L 1989-1998.5

The "Killer Dowel Pin", or KDP, is a concern on 1989 to 1998.5 12 valve Cummins engines. A steel dowel pin is pressed into the cast iron block during assembly. The pin properly aligns the aluminum timing gear housing to the engine block during assembly. Over a period of time, vibration can cause this pin to back out entirely. When this occurs, there are basically 3 possibilities. One, the pin can fall out, bounce off the cam gears and end up in the bottom of the timing gear housing without causing any damage. Two, the pin can dislodge and be forced against the aluminum timing gear housing, cracking it before exiting or falling to the bottom of the case. And three, the worst case scenario, the pin vibrates loose, becomes lodged between the timing gears, and causes catastrophic failure.

In this instance, the pistons slap into the valves and your engine literally demolishes itself. There have been zero reports of successfully repairing an engine that has undergone such a detrimental experience, the engine will have to be replaced. The physical fix for KDP is simple, a small tab that locks the pin in the block, therefore eliminating the chance of it backing out. It is relatively inexpensive, but quite labor intensive as many components must be removed to access the timing gear housing. Many argue that only a small percentage of pins will actually back out but given the nature of the damage that it can cause, the fix is well worth the cost considering the consequences.

 



Air Dog/Fass fuel supply and conditioning systems.


Cummins 5.9L 1998.5-2004

This increases properly pressurized and filtered diesel fuel to your diesel fuel injection system prolonging component life which increases performance and efficiency.

 



Diesel Particulate Filter (DPF)


Cleaning Cummins 6.7L

In some cases the regeneration process will become much more frequent. This is a sign that your DPF is building up more ash than this process can overcome. In this situation the DPF can be removed and ultrasonically cleaned removing 99% of ash deposits, saving you hundreds over the cost of replacement.

(**Some filters may not be serviceable due to age and/or condition).
