The Comprehensive Guide to Buying a Dodge Ram Truck Engine
For decades, the Dodge Ram (now just called 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 heavy-duty labor. When a Ram engine reaches the end of its lifespan, owners deal with a critical decision: repair work, change, or scrap the lorry.
For a lot of owners, replacing the engine is the most economical method to keep a reputable lorry on the road. This guide provides a thorough take a look at everything one requires to know when purchasing a Dodge Ram truck engine, from determining the right model to choosing between brand-new, remanufactured, and utilized alternatives.
1. Understanding the Ram Engine Lineup
Before initiating a purchase, it is important to determine which engine is presently in the car. Dodge and RAM have actually utilized several renowned engines over 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 uses a balance of high horse power and considerable 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 energy, the Pentastar V6 is the go-to. Typically combined with eTorque mild-hybrid technology in later designs, this engine is common in light-duty Ram 1500 trucks.
The 6.7 L Cummins ® Turbo Diesel
In the heavy-duty segment (Ram 2500 and 3500), the Cummins inline-six diesel motor reigns supreme. It 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
Found in older models (early 2000s to early 2010s), these engines were the workhorses of their era. While no longer in production, they stay extensively readily available on the secondary market.
2. Secret Specifications for Popular Ram Engines
When looking for a replacement, comprehending the output and application of the engine is essential. The following table highlights the specs for the most common modern-day Ram engines.

3. Acknowledging the Signs for Engine Replacement
Acquiring a new engine is a significant investment. It is essential to validate that the existing engine is really beyond repair work. Common signs that suggest a replacement is required 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, metallic "knocking" or "tapping" sound normally 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 split block enabling coolant into the combustion chamber.
- Loss of Compression: If the engine struggles to begin or lacks power, a compression test may expose that the cylinders are no longer sealing effectively.
- Metal Shavings in Oil: Finding metal glitter or fragments throughout an oil change is a conclusive sign of internal component disintegration.
4. Buying Options: New, Remanufactured, or Used?
Prospective buyers must weigh the benefits and drawbacks of three main sourcing approaches. The option typically depends upon the truck's age, the owner's budget plan, and the meant usage of the car.
New "Crate" Engines
A dog crate engine is a brand-new assembly from the producer (Mopar).
- Pros: Zero miles, maximum longevity, and an extensive factory warranty.
- Cons: The most pricey option; might exceed the overall worth of older trucks.
Remanufactured Engines
These are secondhand engines that have been entirely taken apart, cleaned up, and rebuilt to initial equipment manufacturer (OEM) requirements. Low-quality parts are replaced with new ones.
- Pros: Generally comes with a 1-to-3-year guarantee; substantially cheaper than brand-new; high dependability.
- Cons: Quality depends heavily on the company doing the remanufacturing.
Used Engines (Salvage Yards)
These are engines pulled straight from damaged or ditched vehicles.
- Pros: The least expensive course; ideal for older trucks or budget-conscious repair work.
- Cons: High risk; variable mileage; typically comes with an extremely brief "startup" guarantee (30-- 90 days).
5. Expense Considerations
The price of a Dodge Ram engine differs considerably based upon the engine type and the condition. Diesel engines, particularly the Cummins, command a much greater price point due to their complexity and sturdiness.
| 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 price 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 ensure a smooth transition and avoid the "incorrect engine" headache, purchasers ought to perform the following checks:
- VIN Verification: Always provide the seller with the car'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 require a "core charge." This suggests the purchaser must send their old, damaged engine back to the seller, or pay an extra charge (ranging from ₤ 500 to ₤ 2,000+).
- Shipping Logistics: Engines are heavy and should be shipped through freight. Validate if the rate includes shipping to a property address or an industrial store with a forklift.
- Included Components: Determine if the purchase is a "long block" (block and heads) or a "total" engine (consisting of intake manifold, fuel injectors, and water pump).
7. Finest Practices for Post-Installation
When the new engine is installed, the work is not yet ended up. Proper burglary and upkeep are important to protecting the financial 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 very first 500 miles to remove any tiny metal particles shed during the preliminary "wearing-in" of the parts.
- Cooling System Refresh: When changing an engine, it is extremely recommended to install a brand-new radiator and water pump. An old, stopped up radiator is a leading reason for early failure in replacement engines.
FAQ: Frequently Asked Questions
For how long does a Dodge Ram engine usually last?
Fuel engines like the 5.7 L HEMI usually last between 200,000 and 250,000 miles with proper maintenance. The 6.7 L Cummins diesel is known to exceed 350,000 to 500,000 miles.
Is it difficult to swap a V6 Ram engine for a V8 HEMI?
While physically possible, it is extremely challenging and costly. It requires a different transmission, engine circuitry harness, Engine Control Module (ECM), and cooling system elements. It is usually more cost-efficient to buy a V8 truck.
What is the "HEMI Tick," and does it imply I need a brand-new engine?
