The Comprehensive Guide to Buying a Dodge Ram Truck Engine
For years, the Dodge Ram (now simply called RAM) has stood as a titan in the American pickup market. Known for its rugged building and construction and immense towing capability, the heart of every Ram truck is its engine. Nevertheless, even the most resilient powerplants eventually catch high mileage, mechanical failure, or the wear and tear of heavy-duty labor. When a Ram engine reaches completion of its life expectancy, owners face a vital decision: repair work, change, or ditch the vehicle.
For a lot of owners, replacing the engine is the most affordable method to keep a reputable automobile on the road. This guide provides a thorough look at whatever one requires to understand when purchasing a Dodge Ram truck engine, from determining the appropriate design to picking in between new, remanufactured, and used alternatives.
1. Comprehending the Ram Engine Lineup
Before starting a purchase, it is important to determine which engine is currently in the car. Dodge and RAM have utilized numerous renowned engines over the years, each with specific performance characteristics 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 horse power and considerable torque. It is a staple in the Ram 1500 and 2500 series.
The 3.6 L Pentastar ™ V6

3. Recognizing the Signs for Engine Replacement
Acquiring a brand-new engine is a substantial financial investment. It is essential to validate that the existing engine is truly beyond repair work. Common symptoms that suggest a replacement is necessary include:
- Excessive Oil Consumption: If the truck needs frequent top-offs without noticeable external leaks, internal seals or piston rings may have failed.
- Engine Knocking: A loud, metal "knocking" or "tapping" sound normally shows worn rod bearings or significant internal damage.
- Blue or White Exhaust Smoke: Persistent blue smoke indicates burning oil, while thick white smoke suggests a blown head gasket or cracked block allowing coolant into the combustion chamber.
- Loss of Compression: If the engine has a hard time to begin or does not have 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 definitive sign of internal part disintegration.
4. Buying Options: New, Remanufactured, or Used?
Prospective buyers must weigh the advantages and disadvantages of 3 primary sourcing methods. The choice often depends on the truck's age, the owner's budget plan, and the meant use of the lorry.
New "Crate" Engines
A dog crate engine is a new assembly from the manufacturer (Mopar).
- Pros: Zero miles, optimum longevity, and a detailed factory warranty.
- Cons: The most costly option; may exceed the overall value of older trucks.
Remanufactured Engines
These are secondhand engines that have been totally dismantled, cleaned up, and rebuilt to initial equipment manufacturer (OEM) requirements. Low-quality parts are replaced with brand-new ones.
- Pros: Generally features a 1-to-3-year warranty; significantly less expensive 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 wrecked or ditched lorries.
- Pros: The least pricey course; perfect for older trucks or budget-conscious repairs.
- Cons: High risk; variable mileage; typically features a very short "start-up" service warranty (30-- 90 days).
5. Cost Considerations
The price of a Dodge Ram engine differs considerably based upon the engine type and the condition. Diesel motor, particularly the Cummins, command a much higher cost point due to their complexity and toughness.
| 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 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 make sure a smooth transition and avoid the "wrong engine" headache, purchasers must carry out the following checks:
- VIN Verification: Always provide the seller with the vehicle's 17-digit VIN. This ensures the engine's harness, sensors, and mounting points match the chassis.
- Core Charge Awareness: Many sellers of remanufactured engines require a "core charge." This indicates the purchaser should send their old, broken engine back to the seller, or pay an additional charge (varying from ₤ 500 to ₤ 2,000+).
- Shipping Logistics: Engines are heavy and should be shipped via freight. Confirm if the cost includes delivering to a domestic address or a business store with a forklift.
- Consisted of 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
Once the new engine is installed, the work is not yet finished. Correct break-in and maintenance are necessary to securing the investment.
- Follow the Break-In Procedure: For 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 first 500 miles to remove any small metal particles shed throughout the initial "wearing-in" of the components.
- Cooling System Refresh: When replacing an engine, it is extremely recommended to set up a new radiator and water pump. An old, clogged radiator is a leading reason for early failure in replacement engines.
FAQ: Frequently Asked Questions
For how long does a Dodge Ram engine generally last?
Gasoline engines like the 5.7 L HEMI normally 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 tough to swap a V6 Ram engine for a V8 HEMI?
While physically possible, it is incredibly hard and pricey. It needs a various transmission, engine circuitry harness, Engine Control Module (ECM), and cooling system parts. It is generally more cost-efficient to buy a V8 truck.
What is the "HEMI Tick," and does it mean I require a new engine?
The "HEMI Tick" is frequently triggered by broken manifold bolts or worn lifters. If it is simply the manifold bolts, it is a simple fix. However, if the lifter has actually stopped working and harmed the camshaft, a top-end restore or full engine replacement may be required.
Will a more recent design Ram engine fit in my older Ram?
Not always. While the block might be the exact same, changes in sensor types (e.g., crank position sensors), EGR systems, and computer system protocols (CAN bus shifts) typically make cross-generational swaps very intricate.
Does a replacement engine impact the truck's resale value?
If a high-quality remanufactured engine with paperwork is utilized, it can really keep or somewhat increase the worth of a high-mileage truck. However, a "scrap yard" swap without any documentation might discourage future buyers.
Purchasing a replacement Dodge Ram truck engine is a significant endeavor that requires careful research study and monetary planning. By understanding the specific needs of the car, comparing the costs of brand-new versus remanufactured units, and ensuring an expert setup, 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 choice guarantees that the Ram stays on the road for lots of more miles of effort.
