The Comprehensive Guide to Buying a Dodge Ram Truck Engine
For years, the Dodge Ram (now just understood as RAM) has actually stood as a titan in the American pickup market. Understood for its rugged construction and enormous towing capacity, the heart of every Ram truck is its engine. However, even the most durable powerplants ultimately give in to high mileage, mechanical failure, or the wear and tear of durable labor. When a Ram engine reaches completion of its lifespan, owners face a vital choice: repair work, change, or scrap the automobile.
For many owners, changing the engine is the most cost-efficient way to keep a trustworthy lorry on the roadway. This guide supplies an in-depth take a look at whatever one requires to know when purchasing a Dodge Ram truck engine, from recognizing the proper model to selecting in between brand-new, remanufactured, and used choices.
1. Comprehending the Ram Engine Lineup
Before initiating a purchase, it is essential to determine which engine is currently in the automobile. Dodge and RAM have made use of numerous renowned engines for many years, each with particular efficiency attributes and compatibility requirements.
The 5.7 L HEMI ® V8
The 5.7 L HEMI is maybe the most well-known engine in the lineup. Understood for its hemispherical combustion chambers, it offers 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

3. Recognizing the Signs for Engine Replacement
Acquiring a new engine is a significant investment. It is essential to verify that the existing engine is really beyond repair. Typical symptoms that recommend a replacement is needed include:
- Excessive Oil Consumption: If the truck requires regular top-offs without visible external leakages, internal seals or piston rings may have stopped working.
- Engine Knocking: A loud, metal "knocking" or "tapping" sound normally shows worn rod bearings or major internal damage.
- Blue or White Exhaust Smoke: Persistent blue smoke shows burning oil, while thick white smoke recommends a blown head gasket or split block allowing coolant into the combustion chamber.
- Loss of Compression: If the engine has a hard time to start or lacks power, a compression test may expose that the cylinders are no longer sealing properly.
- Metal Shavings in Oil: Finding metal shine or shards throughout an oil change is a definitive sign of internal component disintegration.
4. Purchasing Options: New, Remanufactured, or Used?
Prospective buyers must weigh the advantages and disadvantages of three main sourcing techniques. The option typically depends upon the truck's age, the owner's budget plan, and the meant use of the car.
New "Crate" Engines
A crate engine is a new assembly from the manufacturer (Mopar).
- Pros: Zero miles, optimum longevity, and a comprehensive factory service warranty.
- Cons: The most costly option; may go beyond the total value of older trucks.
Remanufactured Engines
These are pre-owned engines that have been completely disassembled, cleaned, and rebuilt to initial devices producer (OEM) specs. Low-grade parts are replaced with brand-new ones.
- Pros: Generally includes a 1-to-3-year service warranty; significantly cheaper than new; high dependability.
- Cons: Quality depends greatly on the business doing the remanufacturing.
Utilized Engines (Salvage Yards)
These are engines pulled directly from wrecked or ditched vehicles.
- Pros: The least pricey course; ideal for older trucks or budget-conscious repair work.
- Cons: High danger; variable mileage; typically includes an extremely brief "startup" warranty (30-- 90 days).
5. Cost Considerations
The cost of a Dodge Ram engine varies significantly based on the engine type and the condition. Diesel motor, specifically the Cummins, command a much higher rate point due to their intricacy and durability.
| 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 quotes for the long block (the engine block and heads) and do not consist of labor for setup.
6. What to Check Before You Buy
To ensure a smooth transition and prevent the "wrong engine" headache, purchasers should perform the following checks:
- VIN Verification: Always supply the seller with the car's 17-digit VIN. This ensures the engine's harness, sensing units, and mounting points match the chassis.
- Core Charge Awareness: Many sellers of remanufactured engines need a "core charge." This means the purchaser needs to 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 delivered via freight. Validate if the rate consists of shipping to a property address or a commercial store with a forklift.
- Included Components: Determine if the purchase is a "long block" (block and heads) or a "complete" engine (including intake manifold, fuel injectors, and water pump).
7. Finest 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 protecting the investment.
- Follow the Break-In Procedure: For brand-new or remanufactured engines, avoid heavy towing or high-speed driving for the first 500 to 1,000 miles.
- Early Oil Change: It is basic practice to change the oil and filter after the first 500 miles to get rid of any tiny metallic particles shed throughout the preliminary "wearing-in" of the parts.
- Cooling System Refresh: When changing an engine, it is highly recommended to set up a brand-new radiator and water pump. An old, blocked radiator is a leading reason for early failure in replacement engines.
FREQUENTLY ASKED QUESTION: Frequently Asked Questions
The length of time does a Dodge Ram engine normally last?
Gasoline engines like the 5.7 L HEMI generally last in between 200,000 and 250,000 miles with correct upkeep. 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?
