The Comprehensive Guide to Buying a Dodge Ram Truck Engine
For decades, the Dodge Ram (now simply referred to as RAM) has stood as a titan in the American pickup truck market. Understood for its rugged building and immense towing capability, the heart of every Ram truck is its engine. However, even the most long lasting powerplants eventually catch high mileage, mechanical failure, or the wear and tear of durable labor. When a Ram engine reaches completion of its life-span, owners face a vital decision: repair work, change, or ditch the lorry.
For many owners, changing the engine is the most affordable way to keep a reputable lorry on the road. This guide offers a thorough take a look at everything one requires to know when buying a Dodge Ram truck engine, from determining the correct model to picking in between brand-new, remanufactured, and used options.
1. Understanding the Ram Engine Lineup
Before starting a purchase, it is important to recognize which engine is presently in the automobile. Dodge and RAM have utilized numerous iconic engines for many years, each with particular performance qualities 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 horsepower and considerable torque. It is a staple in the Ram 1500 and 2500 series.
The 3.6 L Pentastar ™ V6
For those prioritizing fuel effectiveness without compromising energy, the Pentastar V6 is the go-to. Typically matched with read more -hybrid innovation in later models, this engine prevails in light-duty Ram 1500 trucks.
The 6.7 L Cummins ® Turbo Diesel
In the heavy-duty sector (Ram 2500 and 3500), the Cummins inline-six diesel motor reigns supreme. It is prized for its longevity and its ability 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 era. While no longer in production, they stay extensively offered on the secondary market.
2. Secret Specifications for Popular Ram Engines
When shopping for a replacement, comprehending the output and application of the engine is essential. The following table highlights the requirements for the most typical contemporary Ram engines.
| Engine Type | Fuel Type | Displacement | Horsepower (Approx.) | Torque (lb-ft) | Common Applications |
|---|---|---|---|---|---|
| Pentastar V6 | Fuel | 3.6 L | 305 hp | 269 lb-ft | Ram 1500 (2013-Present) |
| HEMI V8 | Gas | 5.7 L | 395 hp | 410 lb-ft | Ram 1500, 2500 (2003-Present) |

3. Recognizing the Signs for Engine Replacement
Getting a brand-new engine is a substantial investment. It is essential to validate that the existing engine is really beyond repair work. Common signs that suggest 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 stopped working.
- Engine Knocking: A loud, metallic "knocking" or "tapping" sound generally suggests worn rod bearings or significant internal damage.
- Blue or White Exhaust Smoke: Persistent blue smoke shows burning oil, while thick white smoke suggests a blown head gasket or broken block permitting coolant into the combustion chamber.
- Loss of Compression: If the engine has a hard time to start or lacks power, a compression test may reveal that the cylinders are no longer sealing appropriately.
- Metal Shavings in Oil: Finding metal shine or shards throughout an oil change is a conclusive sign of internal part disintegration.
4. Purchasing Options: New, Remanufactured, or Used?
Potential buyers should weigh the benefits and drawbacks of 3 primary sourcing methods. The option often depends upon the truck's age, the owner's budget plan, and the planned usage of the automobile.
New "Crate" Engines
A cage engine is a brand-new assembly from the producer (Mopar).
- Pros: Zero miles, maximum durability, and an extensive factory guarantee.
- Cons: The most costly choice; might exceed the overall value of older trucks.
Remanufactured Engines
These are used engines that have been completely taken apart, cleaned, and rebuilt to initial equipment maker (OEM) requirements. Low-grade parts are replaced with new ones.
- Pros: Generally includes a 1-to-3-year service warranty; considerably more affordable than brand-new; high dependability.
- Cons: Quality depends heavily on the company doing the remanufacturing.
Utilized Engines (Salvage Yards)
These are engines pulled directly from trashed or ditched cars.
- Pros: The least costly path; perfect for older trucks or budget-conscious repairs.
- Cons: High risk; variable mileage; generally comes with an extremely brief "start-up" service warranty (30-- 90 days).
5. Cost Considerations
The cost of a Dodge Ram engine varies substantially based upon the engine type and the condition. Diesel motor, particularly the Cummins, command a much higher price point due to their complexity and durability.
| 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 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 guarantee a smooth transition and prevent the "wrong engine" headache, purchasers must perform the following checks:
- VIN Verification: Always supply the seller with the automobile's 17-digit VIN. This makes sure 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 implies the purchaser needs to send their old, broken engine back to the seller, or pay an additional cost (ranging from ₤ 500 to ₤ 2,000+).
- Shipping Logistics: Engines are heavy and must be shipped through freight. Confirm if the cost consists of delivering to a residential address or an industrial shop with a forklift.
- 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 brand-new engine is installed, the work is not yet completed. Appropriate break-in and upkeep are vital to securing the 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 change the oil and filter after the first 500 miles to eliminate any tiny metal particles shed during the preliminary "wearing-in" of the components.
- Cooling System Refresh: When replacing an engine, it is highly suggested to set up a new radiator and water pump. An old, clogged up radiator is a leading cause of early failure in replacement engines.
FREQUENTLY ASKED QUESTION: Frequently Asked Questions
The length of time does a Dodge Ram engine usually last?
Gasoline engines like the 5.7 L HEMI normally last between 200,000 and 250,000 miles with correct upkeep. The 6.7 L Cummins diesel is known to go beyond 350,000 to 500,000 miles.
Is it tough to swap a V6 Ram engine for a V8 HEMI?
While physically possible, it is exceptionally difficult and expensive. It requires a various transmission, engine circuitry harness, Engine Control Module (ECM), and cooling system parts. It is generally more economical to buy a V8 truck.
What is the "HEMI Tick," and does it imply I need a new engine?
The "HEMI Tick" is frequently brought on by broken manifold bolts or used lifters. If it is just the manifold bolts, it is a simple repair. However, if the lifter has stopped working and damaged the camshaft, a top-end restore or full engine replacement might be necessary.
Will a more recent design Ram engine fit in my older Ram?
Not necessarily. While the block may be the very same, changes in sensor types (e.g., crank position sensing units), EGR systems, and computer system protocols (CAN bus shifts) typically make cross-generational swaps really complex.
Does a replacement engine affect the truck's resale worth?
If a high-quality remanufactured engine with documentation is used, it can in fact preserve or a little increase the worth of a high-mileage truck. Nevertheless, a "scrap lawn" swap with no documents might deter future buyers.
