The Comprehensive Guide to Buying a Dodge Ram Truck Engine

For decades, the Dodge Ram (now simply called RAM) has stood as a titan in the American pickup market. Known for its rugged building and construction and tremendous towing capacity, the heart of every Ram truck is its engine. However, even the most resilient powerplants ultimately catch high mileage, mechanical failure, or the wear and tear of heavy-duty labor. When a Ram engine reaches completion of its life expectancy, owners deal with a vital choice: repair work, replace, or scrap the lorry.

For a lot of owners, changing the engine is the most cost-efficient way to keep a reliable vehicle on the roadway. JP Spare Parts USA supplies an extensive take a look at everything one requires to understand when buying a Dodge Ram truck engine, from recognizing the right design to choosing in between new, remanufactured, and used options.


1. Understanding the Ram Engine Lineup

Before starting a purchase, it is essential to identify which engine is currently in the vehicle. Dodge and RAM have used a number of iconic engines throughout the years, each with specific performance characteristics and compatibility requirements.

The 5.7 L HEMI ® V8

The 5.7 L HEMI is possibly the most well-known engine in the lineup. Known for its hemispherical combustion chambers, it provides a balance of high horsepower and significant torque. It is a staple in the Ram 1500 and 2500 series.

The 3.6 L Pentastar ™ V6

For those focusing on fuel effectiveness without compromising energy, the Pentastar V6 is the go-to. Often paired with eTorque mild-hybrid technology in later designs, this engine is common in light-duty Ram 1500 trucks.

The 6.7 L Cummins ® Turbo Diesel

In the sturdy segment (Ram 2500 and 3500), the Cummins inline-six diesel motor reigns supreme. It is valued for its longevity and its capability to produce huge quantities of low-end torque for towing.

The 4.7 L Magnum V8 and 3.7 L PowerTech V6

Discovered in older designs (early 2000s to early 2010s), these engines were the workhorses of their age. While no longer in production, they remain commonly readily available on the secondary market.


When shopping for a replacement, understanding the output and application of the engine is vital. The following table highlights the specs for the most typical modern Ram engines.

3. Recognizing the Signs for Engine Replacement

Purchasing a brand-new engine is a considerable financial investment. It is necessary to verify that the existing engine is genuinely beyond repair. Typical signs that suggest a replacement is needed consist of:

  • Excessive Oil Consumption: If the truck requires frequent top-offs without noticeable external leaks, internal seals or piston rings might have failed.
  • Engine Knocking: A loud, metallic "knocking" or "tapping" sound normally indicates used rod bearings or major internal damage.
  • Blue or White Exhaust Smoke: Persistent blue smoke suggests burning oil, while thick white smoke recommends a blown head gasket or broken block allowing coolant into the combustion chamber.
  • Loss of Compression: If the engine has a hard time to start or lacks power, a compression test might expose that the cylinders are no longer sealing correctly.
  • Metal Shavings in Oil: Finding metal shine or fragments during an oil modification is a definitive indication of internal component disintegration.

4. Buying Options: New, Remanufactured, or Used?

Potential purchasers must weigh the advantages and disadvantages of 3 main sourcing techniques. The choice typically depends on the truck's age, the owner's budget plan, and the meant use of the lorry.

New "Crate" Engines

A dog crate engine is a brand-new assembly from the producer (Mopar).

  • Pros: Zero miles, maximum longevity, and an extensive factory service warranty.
  • Cons: The most costly alternative; might surpass the total worth of older trucks.

Remanufactured Engines

These are secondhand engines that have been entirely taken apart, cleaned, and rebuilt to original devices manufacturer (OEM) specs. Low-grade parts are changed with new ones.

  • Pros: Generally comes with a 1-to-3-year service warranty; considerably cheaper than brand-new; high dependability.
  • Cons: Quality depends heavily on the business doing the remanufacturing.

Utilized Engines (Salvage Yards)

These are engines pulled directly from wrecked or ditched lorries.

  • Pros: The least expensive course; ideal for older trucks or budget-conscious repairs.
  • Cons: High danger; variable mileage; normally features a very short "startup" warranty (30-- 90 days).

5. Expense Considerations

The cost of a Dodge Ram engine differs considerably based upon the engine type and the condition. Diesel engines, particularly the Cummins, command a much greater cost point due to their complexity and toughness.

Engine Category

Estimated Price (Used)

Estimated Price (Remanufactured)

3.6 L Pentastar V6

₤ 1,500-- ₤ 2,500

₤ 3,500-- ₤ 4,500

5.7 L HEMI V8

₤ 2,000-- ₤ 4,000

₤ 4,500-- ₤ 6,500

6.7 L Cummins Diesel

₤ 5,000-- ₤ 9,000

₤ 9,000-- ₤ 14,000

Note: Prices are price quotes for the long block (the engine block and heads) and do not include labor for setup.


6. What to Check Before You Buy

To ensure a smooth transition and prevent the "incorrect engine" headache, purchasers need to carry out the following checks:

  1. VIN Verification: Always provide the seller with the vehicle's 17-digit VIN. This makes sure the engine's harness, sensing units, and installing points match the chassis.
  2. Core Charge Awareness: Many sellers of remanufactured engines require a "core charge." This implies the purchaser must send their old, damaged engine back to the seller, or pay an extra fee (ranging from ₤ 500 to ₤ 2,000+).
  3. Delivering Logistics: Engines are heavy and need to be shipped via freight. Validate if the price consists of delivering to a domestic address or a commercial shop with a forklift.
  4. Consisted of Components: Determine if the purchase is a "long block" (block and heads) or a "total" engine (including consumption manifold, fuel injectors, and water pump).

7. Best Practices for Post-Installation

When the brand-new engine is set up, the work is not yet finished. Appropriate break-in and maintenance are important to safeguarding the financial investment.

  • Follow the Break-In Procedure: For new or remanufactured engines, prevent heavy towing or high-speed driving for the very first 500 to 1,000 miles.
  • Early Oil Change: It is standard practice to alter the oil and filter after the first 500 miles to get rid of any small metallic particles shed during the preliminary "wearing-in" of the components.
  • Cooling System Refresh: When changing an engine, it is extremely advised to install a brand-new radiator and water pump. An old, stopped up radiator is a leading reason for early failure in replacement engines.

FREQUENTLY ASKED QUESTION: Frequently Asked Questions

The length of time does a Dodge Ram engine typically last?

Gas engines like the 5.7 L HEMI generally last between 200,000 and 250,000 miles with correct maintenance. The 6.7 L Cummins diesel is known to surpass 350,000 to 500,000 miles.

Is it difficult to swap a V6 Ram engine for a V8 HEMI?

While physically possible, it is incredibly challenging and pricey. It requires a different transmission, engine electrical wiring harness, Engine Control Module (ECM), and cooling system components. It is often more cost-effective to buy a V8 truck.

What is the "HEMI Tick," and does it mean I require a brand-new engine?

The "HEMI Tick" is typically triggered by damaged manifold bolts or worn lifters. If it is simply the manifold bolts, it is a basic repair. However, if the lifter has failed and harmed the camshaft, a top-end restore or complete engine replacement may be necessary.

Will a more recent model Ram engine fit in my older Ram?

Not necessarily. While the block may be the exact same, modifications in sensor types (e.g., crank position sensing units), EGR systems, and computer system procedures (CAN bus shifts) often make cross-generational swaps extremely intricate.

Does a replacement engine impact the truck's resale value?

If a top quality remanufactured engine with paperwork is utilized, it can in fact preserve or a little increase the worth of a high-mileage truck. Nevertheless, a "scrap backyard" swap without any documents may hinder future buyers.


Buying a replacement Dodge Ram truck engine is a major undertaking that needs careful research study and financial planning. By comprehending the particular needs of the lorry, comparing the expenses of new versus remanufactured units, and making sure a professional setup, owners can restore their truck to its previous magnificence. Whether it is the famous holler of a 5.7 L HEMI or the commercial power of a Cummins diesel, the right engine option makes sure that the Ram stays on the roadway for much more miles of hard work.
