RAM 5500 6.7L Cummins Turbo Diesel Service at TOP CONCEPT Philadelphia
This RAM heavy-duty truck with the legendary 6.7L Cummins Turbo Diesel came into our Northeast Philadelphia shop for engine work. The 6.7L Cummins is one of the most durable diesel engines on the road — but with the displacement and power comes service complexity. We see these trucks for fuel system issues, EGR problems, turbo work, and the periodic deep service that keeps them running for 500k+ miles.
Common 6.7L Cummins Service Items
- Fuel system — CP3 / CP4 high-pressure pump, injectors, fuel filter housing
- EGR & DPF — cooler cleaning, DPF regen issues, soot buildup
- Turbocharger — variable geometry actuator (VGT) sticking, boost leaks
- Cooling system — radiator, water pump, thermostat — critical on a diesel running hot
- Belt and pulley assemblies — serpentine, tensioners, idlers
The Job: What We Do
- Diesel-specific diagnostic scan — read live data from the engine and aftertreatment
- Fuel pressure and rail check — confirm CP3/CP4 health before chasing other faults
- Visual inspection — every hose, harness, sensor on top of the engine
- Targeted repair or service — only what the truck actually needs, with parts you can pick (OEM Mopar / Cummins or quality aftermarket)
- Post-repair verification — clear codes, road test under load, confirm no new faults

Whether you run a 2500, 3500, 4500, or 5500 with the 6.7L Cummins, we handle it. From individual repair to complete diesel engine service, our shop is set up for heavy-duty diesel work.
