The 5.7 L HEMI ® V8
The 5.7 L HEMI is perhaps the most well-known engine in the lineup. Known for its hemispherical combustion chambers, it uses a balance of high horse power and substantial torque. It is a staple in the Ram 1500 and 2500 series.
The 3.6 L Pentastar ™ V6
For those prioritizing fuel performance without sacrificing utility, the Pentastar V6 is the go-to. Typically combined with eTorque mild-hybrid innovation in later models, this engine is common 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 engine reigns supreme. It is valued for its durability and its ability to produce enormous quantities of low-end torque for towing.
The 4.7 L Magnum V8 and 3.7 L PowerTech V6
Found in older models (early 2000s to early 2010s), these engines were the workhorses of their period. While no longer in production, they stay commonly readily available on the secondary market.
2. Key Specifications for Popular Ram Engines
When looking for a replacement, understanding the output and application of the engine is vital. The following table highlights the specs for the most typical modern-day Ram engines.
| Engine Type | Fuel Type | Displacement | Horse Power (Approx.) | Torque (lb-ft) | Common Applications |
|---|---|---|---|---|---|
| Pentastar V6 | Gas | 3.6 L | 305 hp | 269 lb-ft | Ram 1500 (2013-Present) |

3. Recognizing the Signs for Engine Replacement
Purchasing a new engine is a significant financial investment. It is essential to confirm that the existing engine is truly beyond repair work. Common signs that recommend a replacement is necessary include:
- Excessive Oil Consumption: If the truck requires frequent top-offs without noticeable external leakages, internal seals or piston rings might have failed.
- Engine Knocking: A loud, metallic "knocking" or "tapping" sound normally shows used rod bearings or significant internal damage.
- Blue or White Exhaust Smoke: Persistent blue smoke shows burning oil, while thick white smoke recommends a blown head gasket or cracked block enabling coolant into the combustion chamber.
- Loss of Compression: If the engine has a hard time to start or does not have power, a compression test may reveal that the cylinders are no longer sealing properly.
- Metal Shavings in Oil: Finding metal shine or shards throughout an oil modification is a conclusive indication of internal part disintegration.
4. Purchasing Options: New, Remanufactured, or Used?
Prospective buyers should weigh the benefits and drawbacks of 3 main sourcing techniques. The option frequently depends on the truck's age, the owner's budget, 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 durability, and a comprehensive factory warranty.
- Cons: The most costly option; might go beyond the total value of older trucks.
Remanufactured Engines
These are pre-owned engines that have been completely taken apart, cleaned, and rebuilt to original devices manufacturer (OEM) specifications. Low-grade parts are replaced with new ones.
- Pros: Generally features a 1-to-3-year 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 directly from damaged or scrapped vehicles.
- Pros: The least costly course; ideal for older trucks or budget-conscious repair work.
- Cons: High danger; variable mileage; generally comes with an extremely short "start-up" warranty (30-- 90 days).
5. Expense Considerations
The rate of a Dodge Ram engine differs significantly based upon the engine type and the condition. Diesel engines, particularly the Cummins, command a much greater cost point due to their complexity and sturdiness.
| 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 estimates 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 ensure a smooth transition and prevent the "wrong engine" headache, buyers ought to carry out the following checks:
- VIN Verification: Always provide the seller with the lorry's 17-digit VIN. This guarantees the engine's harness, sensors, and mounting points match the chassis.
- Core Charge Awareness: Many sellers of remanufactured engines require a "core charge." Buy Dodge Ram Truck Engine Part means the buyer must send their old, damaged engine back to the seller, or pay an additional fee (varying from ₤ 500 to ₤ 2,000+).
- Shipping Logistics: Engines are heavy and need to be shipped by means of freight. Validate if the rate includes shipping to a residential address or a business store with a forklift.
- Included Components: Determine if the purchase is a "long block" (block and heads) or a "complete" engine (consisting of intake manifold, fuel injectors, and water pump).
7. Finest Practices for Post-Installation
As soon as the new engine is set up, the work is not yet ended up. Correct break-in and maintenance are vital to securing the investment.
- Follow the Break-In Procedure: For brand-new or remanufactured engines, avoid heavy towing or high-speed driving for the very 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 small metallic particles shed throughout the preliminary "wearing-in" of the components.
- Cooling System Refresh: When changing 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 premature failure in replacement engines.
FAQ: Frequently Asked Questions
How long does a Dodge Ram engine typically last?
Gasoline engines like the 5.7 L HEMI usually 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 hard to switch a V6 Ram engine for a V8 HEMI?
While physically possible, it is very hard and costly. It needs a various transmission, engine circuitry harness, Engine Control Module (ECM), and cooling system parts. It is usually more cost-effective to purchase a V8 truck.
What is the "HEMI Tick," and does it indicate I need a brand-new engine?

Will a newer model 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) often make cross-generational swaps really intricate.
Does a replacement engine affect the truck's resale value?
If a premium remanufactured engine with documents is used, it can in fact preserve or slightly increase the value of a high-mileage truck. Nevertheless, a "junk yard" swap with no paperwork may deter future buyers.
