Finding a used 5.9 Cummins engine for sale can be a rewarding experience for those seeking a reliable and powerful engine for various applications. Known for their durability and longevity, these engines are popular choices for trucks, boats, and other heavy-duty machinery. However, navigating the used engine market requires careful consideration. This guide will help you find the right 5.9 Cummins engine for your needs while avoiding potential pitfalls.
What to Look for When Buying a Used 5.9 Cummins Engine
Before you start your search for a used 5.9 Cummins engine, it's crucial to understand what factors determine its condition and overall value.
-
Engine Hours: This is a critical factor. Lower engine hours generally indicate less wear and tear. Always ask for verifiable documentation of the engine's operational history. A high-hour engine might still be functional, but it will likely require more maintenance in the near future.
-
Maintenance Records: Comprehensive maintenance records are essential. They provide valuable insight into the engine's history, revealing any past repairs, replacements, or significant issues. A well-maintained engine will typically command a higher price but offers greater reliability.
-
Compression Test: A compression test is a crucial step in assessing the engine's internal condition. This test measures the pressure within each cylinder, revealing potential problems like worn piston rings or damaged valves. Low compression readings in one or more cylinders suggest significant internal damage.
-
Visual Inspection: Carefully inspect the engine for any signs of damage, corrosion, or leaks. Look for cracks, dents, or excessive rust. Pay close attention to the external components such as the oil pan, intake manifold, and exhaust system.
-
Engine Type: While the term "5.9 Cummins" is common, it encompasses several variations. Specify the exact engine model (e.g., B series, ISB) to ensure compatibility with your application. Different models have varying power outputs and features.
-
Seller Reputation: Buy from a reputable seller with positive reviews or a strong track record. Consider dealing with established engine rebuilders or reputable used parts dealers rather than private sellers with limited information.
Where to Find Used 5.9 Cummins Engines for Sale?
Several avenues exist for finding used 5.9 Cummins engines:

Online Marketplaces: Websites like eBay, Craigslist, and specialized online marketplaces for heavy-duty parts offer a wide selection of used engines. However, be cautious and thoroughly vet any potential sellers.

Truck Salvage Yards: Salvage yards often have a large inventory of used engines, including Cummins engines. These yards can provide a good deal, but the engines might require more extensive inspection.

-
Head Gasket Failure: Head gasket failure can result in coolant leaks and loss of compression. This is a significant issue requiring considerable repair.
How much does a used 5.9 Cummins engine cost?
The price of a used 5.9 Cummins engine varies significantly based on factors like engine hours, condition, model, and the seller. Expect prices to range from a few hundred to several thousand dollars. Always negotiate the price and factor in potential repair costs.
What is the lifespan of a 5.9 Cummins engine?
With proper maintenance, a 5.9 Cummins engine can last for hundreds of thousands of miles or even longer. Its longevity is a significant reason for its popularity among heavy-duty vehicle owners.
