The Comprehensive Guide to Buying a Dodge Ram Truck Engine
For years, the Dodge Ram (now merely 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 long lasting powerplants eventually succumb to high mileage, mechanical failure, or the wear and tear of sturdy labor. When a Ram engine reaches the end of its life expectancy, owners face an important decision: repair, replace, or scrap the lorry.
For many owners, replacing the engine is the most cost-effective method to keep a reliable lorry on the roadway. This guide offers an extensive take a look at everything one needs to understand when buying a Dodge Ram truck engine, from determining the proper design to selecting in between new, remanufactured, and utilized choices.
1. Understanding the Ram Engine Lineup
Before starting a purchase, it is vital to recognize which engine is currently in the lorry. Dodge and RAM have actually utilized a number of iconic engines throughout the years, each with particular performance qualities and compatibility requirements.
The 5.7 L HEMI ® V8
The 5.7 L HEMI is perhaps the most well-known engine in the lineup. Understood for its hemispherical combustion chambers, it provides 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 effectiveness without sacrificing energy, the Pentastar V6 is the go-to. Frequently combined with eTorque mild-hybrid technology in later designs, this engine prevails in light-duty Ram 1500 trucks.
The 6.7 L Cummins ® Turbo Diesel
In the sturdy section (Ram 2500 and 3500), the Cummins inline-six diesel engine reigns supreme. It is valued for its durability and its ability 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 available on the secondary market.

3. Recognizing the Signs for Engine Replacement
Purchasing a brand-new engine is a significant investment. It is crucial to verify that the existing engine is genuinely beyond repair work. Common signs that suggest a replacement is necessary consist of:
- Excessive Oil Consumption: If the truck requires regular top-offs without noticeable external leakages, internal seals or piston rings may have stopped working.
- Engine Knocking: A loud, metal "knocking" or "tapping" sound generally suggests used rod bearings or significant internal damage.
- Blue or White Exhaust Smoke: Persistent blue smoke suggests burning oil, while thick white smoke suggests a blown head gasket or cracked block enabling coolant into the combustion chamber.
- Loss of Compression: If the engine struggles to start or lacks power, a compression test might expose that the cylinders are no longer sealing appropriately.
- 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?
Prospective buyers need to weigh the advantages and disadvantages of 3 primary sourcing techniques. The choice often depends upon the truck's age, the owner's budget, and the planned use of the automobile.
New "Crate" Engines
A crate engine is a brand-new assembly from the maker (Mopar).
- Pros: Zero miles, optimum longevity, and a detailed factory guarantee.
- Cons: The most expensive alternative; may surpass the overall worth of older trucks.
Remanufactured Engines
These are used engines that have actually been totally disassembled, cleaned up, and rebuilt to original devices manufacturer (OEM) requirements. Low-grade parts are changed with new ones.
- Pros: Generally includes a 1-to-3-year guarantee; substantially cheaper than new; high dependability.
- Cons: Quality depends heavily on the business doing the remanufacturing.
Used Engines (Salvage Yards)
These are engines pulled directly from wrecked or ditched vehicles.
- Pros: The least pricey course; suitable for older trucks or budget-conscious repairs.
- Cons: High risk; variable mileage; typically features a very short "startup" warranty (30-- 90 days).
5. Expense Considerations
The cost of a Dodge Ram engine varies considerably based upon the engine type and the condition. Diesel engines, specifically the Cummins, command a much higher cost point due to their complexity and toughness.
| Engine Category | Approximated 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 installation.
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:
- VIN Verification: Always offer the seller with the car's 17-digit VIN. This guarantees the engine's harness, sensing units, and installing points match the chassis.
- Core Charge Awareness: Many sellers of remanufactured engines need a "core charge." This means the buyer should send their old, broken engine back to the seller, or pay an additional cost (varying from ₤ 500 to ₤ 2,000+).
- Delivering Logistics: Engines are heavy and need to be delivered via freight. Verify if the cost includes shipping to a domestic address or a business shop with a forklift.
- Included 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
Once the new engine is installed, the work is not yet ended up. Correct break-in and maintenance are necessary to securing the investment.
- Follow the Break-In Procedure: For brand-new or remanufactured engines, prevent heavy towing or high-speed driving for the first 500 to 1,000 miles.
- Early Oil Change: It is standard practice to change the oil and filter after the very first 500 miles to remove any tiny metallic particles shed throughout the preliminary "wearing-in" of the components.
- Cooling System Refresh: When replacing an engine, it is extremely suggested to install a brand-new radiator and water pump. An old, clogged up radiator is a leading reason for early failure in replacement engines.
FAQ: Frequently Asked Questions
For how long does a Dodge Ram engine typically last?
Gas engines like the 5.7 L HEMI typically last between 200,000 and 250,000 miles with correct upkeep. The 6.7 L Cummins diesel is known to exceed 350,000 to 500,000 miles.
Is it tough to swap a V6 Ram engine for a V8 HEMI?
While physically possible, it is extremely difficult and expensive. It requires a various transmission, engine electrical wiring harness, Engine Control Module (ECM), and cooling system elements. It is often more affordable to purchase a V8 truck.
What is the "HEMI Tick," and does it mean I need a 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 simple fix. However, if the lifter has failed and damaged the camshaft, a top-end restore or complete engine replacement may be needed.
Will a newer design Ram engine fit in my older Ram?
Not always. While the block may be the same, changes in sensing unit types (e.g., crank position sensors), EGR systems, and computer protocols (CAN bus shifts) frequently make cross-generational swaps extremely intricate.
Does a replacement engine affect the truck's resale worth?
If a top quality remanufactured engine with documents is utilized, it can in fact keep or somewhat increase the worth of a high-mileage truck. However, a "junk backyard" swap with no documentation may deter future purchasers.
Buying a replacement Dodge Ram truck engine is a major endeavor that requires mindful research and financial planning. By understanding the specific requirements of the car, comparing the expenses of new versus remanufactured units, and making sure a professional installation, owners can restore their truck to its previous glory. Whether it is the legendary holler of a 5.7 L HEMI or the commercial power of a Cummins diesel, the right engine option ensures that the Ram stays on the roadway for much more miles of effort.
