This guide offers an extensive appearance at whatever one needs to know when buying a Dodge Ram truck engine, from identifying the proper model to picking in between new, remanufactured, and utilized choices.


1. Comprehending the Ram Engine Lineup

Before initiating a purchase, it is vital to recognize which engine is currently in the automobile. Dodge and RAM have actually made use of numerous renowned engines throughout the years, each with specific efficiency characteristics and compatibility requirements.

The 5.7 L HEMI ® V8

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

The 3.6 L Pentastar ™ V6

For those focusing on fuel performance without sacrificing energy, the Pentastar V6 is the go-to. Typically combined with eTorque mild-hybrid innovation in later designs, this engine prevails in light-duty Ram 1500 trucks.

The 6.7 L Cummins ® Turbo Diesel

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

The 4.7 L Magnum V8 and 3.7 L PowerTech V6

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


When looking for a replacement, understanding the output and application of the engine is vital. The following table highlights the requirements for the most common contemporary Ram engines.

3. Recognizing the Signs for Engine Replacement

Purchasing a brand-new engine is a considerable financial investment. It is very important to verify that the existing engine is genuinely beyond repair work. Typical symptoms that suggest a replacement is necessary include:

  • Excessive Oil Consumption: If the truck needs regular top-offs without visible external leakages, internal seals or piston rings might have stopped working.
  • Engine Knocking: A loud, metal "knocking" or "tapping" sound usually shows used rod bearings or significant internal damage.
  • Blue or White Exhaust Smoke: Persistent blue smoke indicates burning oil, while thick white smoke recommends a blown head gasket or split block enabling coolant into the combustion chamber.
  • Loss of Compression: If the engine has a hard time to begin or does not have power, a compression test might expose that the cylinders are no longer sealing appropriately.
  • Metal Shavings in Oil: Finding metal shine or shards throughout an oil modification is a definitive indication of internal element disintegration.

4. Purchasing  Dodge Ram 1500 Truck Part USA : New, Remanufactured, or Used?

Potential purchasers should weigh the benefits and drawbacks of three main sourcing methods. The choice typically depends upon the truck's age, the owner's budget plan, and the planned use of the lorry.

New "Crate" Engines

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

  • Pros: Zero miles, maximum longevity, and a thorough factory service warranty.
  • Cons: The most costly choice; may exceed the overall worth of older trucks.

Remanufactured Engines

These are used engines that have been entirely disassembled, cleaned up, and rebuilt to initial devices maker (OEM) requirements. Low-quality parts are changed with new ones.

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

Utilized Engines (Salvage Yards)

These are engines pulled straight from trashed or scrapped vehicles.

  • Pros: The least pricey path; suitable for older trucks or budget-conscious repair work.
  • Cons: High threat; variable mileage; generally features an extremely short "startup" service warranty (30-- 90 days).

5. Cost Considerations

The price of a Dodge Ram engine differs significantly based upon the engine type and the condition. Diesel engines, specifically the Cummins, command a much higher cost point due to their intricacy and toughness.

Engine CategoryEstimated 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

Keep in mind: Prices are quotes for the long block (the engine block and heads) and do not consist of labor for installation.


6. What to Check Before You Buy

To make sure a smooth transition and avoid the "incorrect engine" headache, buyers should carry out the following checks:

  1. VIN Verification: Always supply the seller with the automobile's 17-digit VIN. This makes sure the engine's harness, sensors, and mounting points match the chassis.
  2. Core Charge Awareness: Many sellers of remanufactured engines require a "core charge." This indicates the purchaser should send their old, damaged engine back to the seller, or pay an extra fee (ranging from ₤ 500 to ₤ 2,000+).
  3. Shipping Logistics: Engines are heavy and need to be shipped through freight. Verify if the rate includes shipping to a residential address or an industrial store with a forklift.
  4. Included Components: Determine if the purchase is a "long block" (block and heads) or a "complete" engine (including consumption manifold, fuel injectors, and water pump).

7. Best Practices for Post-Installation

As soon as the new engine is installed, the work is not yet ended up. Appropriate break-in and maintenance are important to securing the financial investment.

  • Follow the Break-In Procedure: For new or remanufactured engines, prevent heavy towing or high-speed driving for the first 500 to 1,000 miles.
  • Early Oil Change: It is basic practice to alter the oil and filter after the very first 500 miles to remove any tiny metallic particles shed throughout the preliminary "wearing-in" of the parts.
  • Cooling System Refresh: When changing an engine, it is extremely suggested to set up a 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

How long does a Dodge Ram engine normally last?

Fuel engines like the 5.7 L HEMI usually last between 200,000 and 250,000 miles with appropriate maintenance. The 6.7 L Cummins diesel is understood to exceed 350,000 to 500,000 miles.

Is it hard to switch a V6 Ram engine for a V8 HEMI?

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

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

The "HEMI Tick" is typically brought on by damaged manifold bolts or used lifters. If it is simply the manifold bolts, it is a simple repair. Nevertheless, if the lifter has stopped working and harmed the camshaft, a top-end restore or complete engine replacement may be required.

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

Not necessarily. While the block may be the exact same, changes in sensing unit types (e.g., crank position sensing units), EGR systems, and computer procedures (CAN bus shifts) typically make cross-generational swaps extremely complex.

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

If a top quality remanufactured engine with documents is used, it can in fact preserve or somewhat increase the worth of a high-mileage truck. However, a "junk backyard" swap with no documents might discourage future buyers.


Buying a replacement Dodge Ram truck engine is a major undertaking that requires mindful research study and financial planning. By comprehending the particular needs of the vehicle, comparing the expenses of new versus remanufactured units, and making sure an expert setup, owners can restore their truck to its former splendor. Whether it is the legendary holler of a 5.7 L HEMI or the industrial power of a Cummins diesel, the ideal engine choice makes sure that the Ram remains on the roadway for much more miles of effort.
