How to Choose the Right Used Cummins Engine
Selecting the right engine involves more than just knowing the make and model. You need to consider factors like application, compatibility, and intended usage. Here are some tips to help guide your purchase:
Confirm Compatibility
Always check your vehicle’s specifications to ensure the engine will be a proper fit. This includes matching the engine serial number, ECM programming, and mount locations.
Review Engine History
Look for details about prior use, service records, and mileage. Engines from low-stress environments—such as generators or light-duty vehicles—often have longer life left.
Ask About Warranties
While used engines are sold as-is in many cases, Nationwide Truck Parts offers limited warranties on select units to give you extra peace of mind.
Consider Upgrades
Some customers use the opportunity to upgrade to a higher-performing engine. Make sure your transmission and supporting components can handle any increase in output.
