What Makes the 5.7 L V8 HEMI Stand Out?
The 5.7 L V8 HEMI is celebrated for its innovative design and robust performance. Here are some of the key features that make it a standout engine:

- Durability: Built with high-quality materials and engineering, the 5.7 L HEMI is known to last for hundreds of thousands of miles with proper maintenance.
Performance and Applications
The 5.7 L V8 HEMI is a versatile engine used in a wide range of vehicles, from muscle cars like the Dodge Charger and Challenger to workhorses like the Ram 1500. Its ability to deliver both high performance and reliability makes it a favorite among drivers who need power for towing, hauling, or spirited driving.
In trucks like the Ram 1500, the 5.7 L HEMI provides excellent towing capacity, often exceeding 10,000 pounds when properly equipped. In performance cars, it offers thrilling acceleration and a satisfying exhaust note that enthusiasts love.
Common Concerns and Maintenance
While the 5.7 L HEMI is generally reliable, no engine is without its potential issues. Here are some common concerns and tips for maintaining this engine:
- Ticking Noise: Some owners report a "HEMI tick," which can be caused by lifter issues or exhaust manifold bolts. Regular inspections and addressing problems early can prevent costly repairs.
- Oil Consumption: Like many V8 engines, the 5.7 L HEMI may consume oil over time. Regular oil checks and changes are essential to keep the engine running smoothly.
- Fuel Economy: While MDS technology helps, the 5.7 L HEMI is still a V8 engine, and fuel economy may not be its strongest suit. Drivers should be prepared for higher fuel costs, especially in city driving.

Frequently Asked Questions
What is the most common problem with the 5.7 Hemi?
Many of the reported problems surrounding the 5.7-liter Hemi include strange engine sounds, and stalling behavior that occurs while at speed. The 2014 Ram 1500 (which includes the 5.7-liter Hemi V8) has received the most complaints against the truck over the last decade, pointing primarily to engine issues.
How long do 5.7 Hemi engines last?
Hemis are awesome engines... You could easily have another 150k miles if it was well maintained. Even after that a rebuild will not be too costly and you good for another possible decade+ of usage.
What is the big deal about a Hemi engine?
In simple terms, the hemispherical shape delivers more pressure in the piston cylinder combustion chamber than the wedge shape. The more efficient air intake system and spark plug position cause earlier combustion, resulting in higher efficiency and power. Essentially, the fuel burns more quickly.
Are Hemi engines expensive to maintain?
The biggest downsides of having a Hemi engine are its limiting valve configuration, high upfront and maintenance costs, complicated design, and heavy/unwieldy nature.
What year 5.7 Hemi should I avoid?
While the 5.7L HEMI is a powerful and reliable motor, it isn't free from bugs. A few model years, in particular, have proven more problematic than others. Model years 2011 and 2012 stand out when it comes to bad years for the 5.7L HEMI, with 2012 being an especially lousy period for Ram pickups.

Is the Hemi 5.7 a reliable engine?
The 5.7 is pretty reliable. The hemi tick is a thing later in their lifetimes, sure, but that's a symptom rather than a problem. I wouldn't buy one ticking already but it's not the worst thing that could happen. I feel like my 5.7 is giving me fewer problems than my 3.6 was at the same mileage.
