The Comprehensive Guide to Buying a Dodge Ram Truck Engine
For decades, the Dodge Ram (now just called RAM) has actually stood as a titan in the American pickup truck market. Known for its rugged construction and enormous towing capacity, the heart of every Ram truck is its engine. However, even the most resilient powerplants ultimately surrender to high mileage, mechanical failure, or the wear and tear of heavy-duty labor. When a Ram engine reaches completion of its lifespan, owners face an important choice: repair, change, or ditch the lorry.
For many owners, changing the engine is the most affordable method to keep a dependable automobile on the road. This guide offers a thorough take a look at whatever one requires to know when purchasing a Dodge Ram truck engine, from recognizing the appropriate design to choosing between new, remanufactured, and utilized alternatives.
1. Understanding the Ram Engine Lineup
Before starting a purchase, it is essential to recognize which engine is presently in the car. Dodge and RAM have actually used several renowned engines for many years, each with specific performance attributes and compatibility requirements.
The 5.7 L HEMI ® V8
The 5.7 L HEMI is perhaps the most popular engine in the lineup. Understood for its hemispherical combustion chambers, it provides a balance of high horse power and significant 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 utility, the Pentastar V6 is the go-to. Frequently combined with eTorque mild-hybrid innovation in later designs, this engine is typical in light-duty Ram 1500 trucks.
The 6.7 L Cummins ® Turbo Diesel
In the durable sector (Ram 2500 and 3500), the Cummins inline-six diesel engine reigns supreme. It is valued for its longevity and its capability 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 period. While no longer in production, they remain extensively offered on the secondary market.
2. Key Specifications for Popular Ram Engines
When shopping for a replacement, understanding the output and application of the engine is essential. The following table highlights the requirements for the most common modern Ram engines.
| Engine Type | Fuel Type | Displacement | Horse Power (Approx.) | Torque (lb-ft) | Common Applications |
|---|---|---|---|---|---|
| Pentastar V6 | Gasoline | 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. Acknowledging the Signs for Engine Replacement
Getting a brand-new engine is a substantial investment. It is necessary to verify that the existing engine is truly beyond repair work. Typical signs that recommend a replacement is required consist of:
- Excessive Oil Consumption: If the truck needs frequent top-offs without visible external leaks, internal seals or piston rings might have failed.
- Engine Knocking: A loud, metallic "knocking" or "tapping" sound generally shows used rod bearings or significant internal damage.
- Blue or White Exhaust Smoke: Persistent blue smoke suggests burning oil, while thick white smoke recommends a blown head gasket or broken block allowing coolant into the combustion chamber.
- Loss of Compression: If the engine struggles to begin or does not have power, a compression test may reveal that the cylinders are no longer sealing effectively.
- Metal Shavings in Oil: Finding metal shine or fragments throughout an oil change is a definitive indication of internal element disintegration.
4. Purchasing Options: New, Remanufactured, or Used?
Prospective buyers should weigh the advantages and disadvantages of 3 main sourcing methods. The choice frequently depends upon the truck's age, the owner's budget plan, and the intended use of the automobile.
New "Crate" Engines
A crate engine is a brand-new assembly from the maker (Mopar).
- Pros: Zero miles, maximum durability, and a detailed factory guarantee.
- Cons: The most pricey alternative; may surpass the total worth of older trucks.
Remanufactured Engines
These are pre-owned engines that have actually been totally disassembled, cleaned, and rebuilt to initial devices manufacturer (OEM) specifications. Low-quality parts are replaced with new ones.
- Pros: Generally comes with a 1-to-3-year service warranty; substantially more affordable than new; high dependability.
- Cons: Quality depends heavily on the company doing the remanufacturing.
Utilized Engines (Salvage Yards)
These are engines pulled directly from damaged or ditched lorries.
- Pros: The least costly path; suitable for older trucks or budget-conscious repairs.
- Cons: High threat; variable mileage; usually comes with a very short "start-up" guarantee (30-- 90 days).
5. Expense Considerations
The rate of a Dodge Ram engine differs substantially based upon the engine type and the condition. Diesel engines, specifically the Cummins, command a much higher rate 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 consist of labor for installation.
6. What to Check Before You Buy
To make sure a smooth transition and avoid the "incorrect engine" headache, buyers must carry out the following checks:
- VIN Verification: Always provide the seller with the vehicle's 17-digit VIN. jpsparepartsusa.com ensures the engine's harness, sensors, and installing points match the chassis.
- Core Charge Awareness: Many sellers of remanufactured engines require a "core charge." This suggests the buyer should send their old, damaged engine back to the seller, or pay an extra charge (varying from ₤ 500 to ₤ 2,000+).
- Delivering Logistics: Engines are heavy and must be shipped through freight. Confirm if the cost includes delivering to a domestic address or a commercial shop 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
Once the brand-new engine is set up, the work is not yet ended up. Correct break-in and upkeep are vital to securing the financial 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 small metal particles shed during the initial "wearing-in" of the elements.
- Cooling System Refresh: When changing an engine, it is extremely suggested to install a brand-new radiator and water pump. An old, blocked radiator is a leading cause of premature failure in replacement engines.
FREQUENTLY ASKED QUESTION: Frequently Asked Questions
How long does a Dodge Ram engine normally last?
Fuel engines like the 5.7 L HEMI normally last in between 200,000 and 250,000 miles with proper maintenance. The 6.7 L Cummins diesel is understood 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 incredibly tough and costly. It requires a various transmission, engine electrical wiring harness, Engine Control Module (ECM), and cooling system parts. It is generally more cost-effective to buy a V8 truck.
What is the "HEMI Tick," and does it suggest I require a new engine?
The "HEMI Tick" is frequently brought on by broken manifold bolts or worn lifters. If it is simply the manifold bolts, it is an easy fix. Nevertheless, if the lifter has actually failed and harmed the camshaft, a top-end reconstruct or full engine replacement might be essential.
Will a more recent design Ram engine fit in my older Ram?
Not necessarily. While the block might be the same, modifications in sensor types (e.g., crank position sensing units), EGR systems, and computer procedures (CAN bus shifts) frequently make cross-generational swaps extremely complicated.
Does a replacement engine affect the truck's resale value?
If a high-quality remanufactured engine with documentation is utilized, it can in fact keep or a little increase the worth of a high-mileage truck. However, a "junk yard" swap without any paperwork may deter future purchasers.
