Is the 4.7 L V8 a good engine?

Yes — in the right vehicle and with proper maintenance, the 4.7 L V8 offers solid reliability, robust low-end torque, and affordable ownership, though it trails modern engines in fuel economy and refinement.


The 4.7 L V8 is part of Chrysler’s PowerTech/Magnum family and was used in Dodge pickups, SUVs, and several Jeep models from the late 1990s through the 2000s. It earned a reputation as a durable, workhorse engine that could handle everyday driving and towing duties without requiring premium fuel or expensive maintenance. This article assesses its strengths, weaknesses, and what to consider if you’re evaluating a vehicle equipped with this engine today.


What makes it durable and useful


Below are the core reasons buyers historically embraced the 4.7 L V8, especially for trucks and larger SUVs that prioritize torque and reliability.



  • Strong low-end torque ideal for towing and hauling

  • Rugged construction with a sturdy block and long-lived internals

  • Relatively straightforward maintenance and broad aftermarket support

  • Good weight-to-power balance for work-oriented applications

  • Wide availability of used vehicles and affordable replacement parts


These attributes have made the 4.7 L V8 a practical choice for buyers who need dependable performance without chasing the latest tech.


Where it can fall short


Like any older engine, the 4.7 L V8 has potential drawbacks that should inform a purchase or ownership plan.



  • Fuel economy is modest by modern standards, especially in full-size SUVs and trucks

  • Age-related wear can affect gaskets, seals, and timing components, leading to leaks or noisy operation

  • Common maintenance items include intake manifold and valve-cover gasket leaks on higher-mileage examples

  • Less refinement and fewer modern emissions/features compared with newer engines


For buyers, these risks are manageable with proactive maintenance and clear service histories, but they can add to ownership costs if neglected.


Maintenance tips and what to inspect


Preparation and regular service are key to keeping a 4.7 L V8 running smoothly. Here’s what to look for and how to keep the engine healthy.



  • Check for a documented history of timing chain/tensioner work and listen for any startup or idle rattling

  • Inspect for oil leaks around valve covers, the timing cover, and the rear main seal

  • Ensure the cooling system is in good condition to prevent overheating and related damage

  • Verify ignition components (spark plugs, coils) and the fuel system are in good shape to avoid misfires and rough running


With diligent maintenance, the 4.7 L V8 can continue delivering dependable performance in aging Dodge and Jeep models.


Is it still a sensible choice today?


Choosing a vehicle with the 4.7 L V8 depends on your priorities. If you want proven torque, affordable maintenance, and a capable used SUV or pickup, it can be a solid option. If your priorities include top-tier fuel economy, advanced driver assists, and the latest emissions technology, you may be better served by a newer engine or platform.


Alternatives to consider


Budget, mileage, and intended use will shape whether a newer V8 or a modern V6 option makes more sense. Here are common pathways buyers explore when weighing options.



  • 5.7L Hemi or newer V8s for smoother operation and improved efficiency

  • Modern turbocharged V6 options offering a blend of torque and better fuel economy

  • Diesel variants in some trucks for higher towing efficiency, depending on model compatibility


Ultimately, your choice should balance purchase price, expected maintenance, and how you plan to use the vehicle.


Summary


The 4.7 L V8 remains a durable, torque-rich option for older Dodge and Jeep models when properly maintained. It offers practical advantages like easy parts availability and strong low-end power, but it lags behind modern engines in fuel economy and refinement. For buyers on a tighter budget who value reliability and towing capability, a well-maintained 4.7 L V8 can still be a sensible pick. Always review maintenance history, inspect for leaks and timing components, and compare with newer alternatives to ensure it fits your needs.
