Our Cummins gas and diesel engine repair services
Cummins diesel engines are built tough, but even the most reliable setups can run into problems—especially under heavy use or high mileage. From older 5.9L models to newer 6.7L platforms, we’ve seen the wear points and know what to look for when something’s off. Below are some of the most common issues we address through our Cummins engine repair services, handled by our skilled and ASE-certified team.
Head gasket and combustion sealing repairs
High-load hauling and towing can cause head gasket failure over time, especially in 5.9L and 6.7L Cummins engines. We’ll remove the cylinder head, inspect for cracks or warping, and replace the gasket with high-quality components to keep coolant, oil, and combustion gases where they belong.
Electrical repairs and connector replacement
Some newer Ram trucks with Cummins diesel setups have had issues with electrical connectors overheating, which can pose a fire risk. Our repair process includes diagnosing damaged wires or melted connectors, cleaning or replacing the affected parts, and making sure your electrical system is safe and reliable.
Fuel system and injection service
Over time, components like the CP3 pump, injectors, and fuel rail sensors wear down—leading to performance loss, rough starts, or even stalling. We’ll test the diesel fuel pressure and flow, replace worn-out parts, and get your engine running clean and strong again.
Turbocharger repairs and replacement
Boost pressure problems or loss of power can often be traced back to a faulty turbo. Our shop will inspect the turbocharger for leaks, shaft play, or carbon buildup, and then either service or replace the unit to restore full engine performance.
Engine repower and replacement
If your diesel engine is beyond repair or too costly to fix, we offer complete engine repowers using new or remanufactured Cummins engines. We’ll remove the old unit, install the replacement, and test all related systems to get you back on the road with renewed reliability.
Cooling system diagnostics and repair
A failing cooling system can lead to overheating and serious engine damage. We flush the old coolant, inspect belts and hoses, and repair or replace any worn components to keep things running at the right temperature.
Emissions system service and software updates
From faulty EGR valves to outdated software that triggers emissions warnings, emissions systems on Cummins trucks can cause issues if ignored. We inspect the exhaust and EGR components, update your software when needed, and repair or clean components to keep your truck legal and running right.
Engine diagnostics
If your Cummins engine is running rough, losing power, or triggering warning lights, we’ll get to the bottom of it with precise engine diagnostics. Our team uses the latest diagnostic tools to pinpoint issues fast and guide you toward the right repair services to keep your diesel truck performing like it should.
If your Cummins-powered car or truck is showing signs of trouble—whether it’s loss of power, rough starts, or fluid leaks, bring it to AGM Auto Service in Shippensburg, PA, where our experienced crew delivers honest, dealership-level Cummins engine repair without the hassle or markup.
