The Comprehensive Guide to Buying a Dodge Ram Truck Engine

For years, the Dodge Ram (now just called RAM) has actually stood as a titan in the American pickup truck market. Known for its rugged building and construction and immense towing capability, the heart of every Ram truck is its engine. However, even the most resilient powerplants eventually yield to high mileage, mechanical failure, or the wear and tear of durable labor. When a Ram engine reaches completion of its lifespan, owners deal with a vital decision: repair work, replace, or scrap the automobile.

For most owners, replacing the engine is the most cost-effective way to keep a dependable car on the roadway. This guide offers an in-depth take a look at whatever one requires to understand when purchasing a Dodge Ram truck engine, from recognizing the correct model to picking between brand-new, remanufactured, and utilized alternatives.


1. Comprehending the Ram Engine Lineup

Before initiating a purchase, it is important to recognize which engine is presently in the automobile. Dodge and RAM have actually utilized a number of iconic engines for many years, each with particular performance characteristics and compatibility requirements.

The 5.7 L HEMI ® V8

The 5.7 L HEMI is perhaps the most popular engine in the lineup. Known for its hemispherical combustion chambers, it offers a balance of high horse power and significant torque. It is a staple in the Ram 1500 and 2500 series.

The 3.6 L Pentastar ™ V6

For those prioritizing fuel performance without compromising energy, the Pentastar V6 is the go-to. Frequently coupled with eTorque mild-hybrid technology in later models, this engine prevails in light-duty Ram 1500 trucks.

The 6.7 L Cummins ® Turbo Diesel

In the heavy-duty section (Ram 2500 and 3500), the Cummins inline-six diesel motor reigns supreme.  JP Spare Parts USA  is valued for its longevity and its capability to produce huge amounts 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 period. While no longer in production, they remain extensively offered on the secondary market.


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

3. Acknowledging the Signs for Engine Replacement

Acquiring a brand-new engine is a substantial investment. It is essential to validate that the existing engine is genuinely beyond repair. Common signs that recommend a replacement is necessary consist of:

  • Excessive Oil Consumption: If the truck needs regular top-offs without visible external leaks, internal seals or piston rings might have stopped working.
  • Engine Knocking: A loud, metal "knocking" or "tapping" sound typically shows used rod bearings or major internal damage.
  • Blue or White Exhaust Smoke: Persistent blue smoke suggests burning oil, while thick white smoke suggests a blown head gasket or split block allowing coolant into the combustion chamber.
  • Loss of Compression: If the engine struggles to start or lacks power, a compression test may expose that the cylinders are no longer sealing appropriately.
  • Metal Shavings in Oil: Finding metal shine or fragments during an oil modification is a conclusive indication of internal component disintegration.

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

Potential purchasers should weigh the benefits and drawbacks of three primary sourcing approaches. The choice frequently depends on the truck's age, the owner's budget plan, and the meant usage of the vehicle.

New "Crate" Engines

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

  • Pros: Zero miles, optimum longevity, and a thorough factory warranty.
  • Cons: The most pricey choice; might exceed the total worth of older trucks.

Remanufactured Engines

These are pre-owned engines that have actually been entirely disassembled, cleaned, and rebuilt to initial equipment producer (OEM) specifications. Low-grade parts are changed with new ones.

  • Pros: Generally comes with a 1-to-3-year service warranty; significantly more affordable than new; high reliability.
  • Cons: Quality depends heavily on the company doing the remanufacturing.

Used Engines (Salvage Yards)

These are engines pulled straight from damaged or scrapped lorries.

  • Pros: The least pricey course; ideal for older trucks or budget-conscious repair work.
  • Cons: High risk; variable mileage; generally comes with an extremely brief "startup" guarantee (30-- 90 days).

5. Expense Considerations

The rate of a Dodge Ram engine varies significantly based upon the engine type and the condition. Diesel engines, particularly the Cummins, command a much greater cost point due to their intricacy and durability.

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 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 guarantee a smooth transition and prevent the "wrong engine" headache, purchasers should perform the following checks:

  1. VIN Verification: Always provide the seller with the automobile's 17-digit VIN. This guarantees 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 means the purchaser should send their old, broken engine back to the seller, or pay an extra cost (ranging from ₤ 500 to ₤ 2,000+).
  3. Delivering Logistics: Engines are heavy and should be shipped through freight. Validate if the cost includes delivering to a domestic address or a business store with a forklift.
  4. Consisted of Components: Determine if the purchase is a "long block" (block and heads) or a "total" engine (consisting of consumption manifold, fuel injectors, and water pump).

7. Best Practices for Post-Installation

When the brand-new engine is installed, the work is not yet finished. Appropriate break-in and upkeep are important to securing the investment.

  • Follow the Break-In Procedure: For brand-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 basic practice to alter the oil and filter after the very first 500 miles to eliminate any small metallic particles shed during the preliminary "wearing-in" of the components.
  • Cooling System Refresh: When replacing an engine, it is extremely advised to set up a new radiator and water pump. An old, blocked radiator is a leading cause of premature failure in replacement engines.

FAQ: Frequently Asked Questions

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

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

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

While physically possible, it is very tough and expensive. It needs a different transmission, engine wiring harness, Engine Control Module (ECM), and cooling system components. It is usually more cost-effective to buy a V8 truck.

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

The "HEMI Tick" is often triggered by damaged manifold bolts or worn lifters. If it is simply the manifold bolts, it is a simple fix. Nevertheless, if the lifter has actually stopped working and damaged the camshaft, a top-end restore or complete engine replacement might be needed.

Will a newer model Ram engine fit in my older Ram?

Not necessarily. While the block may be the very same, modifications in sensor types (e.g., crank position sensors), EGR systems, and computer system protocols (CAN bus shifts) often make cross-generational swaps very complicated.

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

If a premium remanufactured engine with paperwork is used, it can in fact keep or somewhat increase the worth of a high-mileage truck. However, a "junk backyard" swap without any documents might discourage future buyers.


Buying a replacement Dodge Ram truck engine is a major endeavor that requires mindful research study and monetary planning. By understanding the particular requirements of the vehicle, comparing the costs of new versus remanufactured systems, and guaranteeing an expert setup, owners can restore their truck to its previous glory. Whether it is the famous roar of a 5.7 L HEMI or the industrial power of a Cummins diesel, the right engine choice guarantees that the Ram stays on the road for a lot more miles of effort.
