The Ultimate Guide to Buying a Dodge Ram Replacement Engine
The Dodge Ram, now professionally known just as the RAM truck, has actually solidified its location as a cornerstone of American vehicle engineering. Known for its rugged resilience and significant towing capability, these trucks are often driven for hundreds of thousands of miles. However, even the most robust powertrains ultimately catch use and tear, high mileage, or mechanical failure. When a RAM owner deals with a disastrous engine problem, the decision frequently boils down to two options: acquire a brand-new lorry or replace the engine.
Offered the skyrocketing costs of modern pickup, changing the engine is frequently the more financially sound choice. This guide supplies a thorough exploration of how to navigate the procedure of purchasing a Dodge Ram engine, covering the kinds of engines offered, sourcing alternatives, and important technical factors to consider.
1. Understanding the Popular Dodge Ram Engine Options
Before browsing for a replacement, it is important to determine exactly which engine powers the vehicle. Dodge has used a range of powertrains over the decades, ranging from fuel-efficient V6s to heavy-duty Cummins diesels.
The 5.7 L HEMI V8
Perhaps the most iconic engine in the RAM lineup is the 5.7 L HEMI. Famous for its hemispherical combustion chambers, this engine offers a blend of horse power and torque that attract both daily motorists and those who utilize their trucks for light-to-medium towing. Buyers must understand particular iterations, such as those featuring Multi-Displacement Systems (MDS) or Variable Valve Timing (VVT).
The 6.7 L Cummins Turbo Diesel
For durable RAM 2500 and 3500 models, the Cummins inline-six diesel engine is the gold requirement. Known for extreme durability and massive torque output, changing one of these engines is a considerable financial investment however can include another years or more to the truck's functional life.
The 3.6 L Pentastar V6
Found in many late-model RAM 1500s, this engine is developed for fuel efficiency and dependability. While it does not have the raw power of the V8 or Diesel, it is a popular option for fleet automobiles and commuters.
Technical Comparison Table
The following table highlights the requirements of the most common engines discovered in the Dodge Ram lineup over the last decade.
| Engine Type | Displacement | Setup | Horsepower (Approx.) | Torque (lb-ft) | Fuel Type |
|---|---|---|---|---|---|
| Pentastar | 3.6 L | V6 | 305 hp | 269 lb-ft | Gas |
| HEMI | 5.7 L | V8 | 395 hp | 410 lb-ft | Gas |
| HEMI (Heavy Duty) | 6.4 L | V8 | 410 hp | 429 lb-ft | Gasoline |
| Cummins | 5.9 L (Older) | I6 | 325 hp | 610 lb-ft | Diesel |
| Cummins | 6.7 L | I6 | 370-- 420 hp | 850-- 1,075 lb-ft | Diesel |
2. Choosing the Right Replacement Category
When looking to buy a Dodge Ram engine, the buyer must choose in between 3 primary classifications: New (Crate), Remanufactured, or Used. Each has its own set of advantages and drawbacks.
New (Crate) Engines
A "dog crate engine" is a new engine manufactured by Mopar (the parts division for RAM). website is the most expensive route however offers the highest level of security.
- Pros: Zero miles, complete manufacturer service warranty, factory-fresh elements.
- Cons: Extremely high price point, might surpass the value of an older truck.
Remanufactured Engines
Remanufactured engines are often considered the "sweet area" for a lot of RAM owners. These engines are disrobed to the block, cleaned up, and rebuilt with new or machined parts to fulfill or go beyond initial equipment manufacturer (OEM) specs.
- Pros: Corrects known factory problems (like the "HEMI tick"), consists of a service warranty (often 3 years/100,000 miles), and is significantly cheaper than a new engine.
- Cons: Quality depends greatly on the reputation of the remanufacturer.
Used Engines
Sourced from salvage lawns or donor vehicles, utilized engines are the most budget-friendly alternative.
- Pros: Lowest expense, frequently includes devices like the alternator or intake manifold.
- Cons: High threat, minimal or no service warranty, unknown upkeep history.
3. Secret Factors to Consider Before Purchase
Buying an engine is a complicated transaction. To guarantee compatibility and durability, numerous aspects must be validated before any money modifications hands.
The VIN Check
The Vehicle Identification Number (VIN) is the most dependable method to recognize the correct engine. The 8th digit of a RAM's VIN particularly represents the engine code. When communicating with sellers, supplying the VIN makes sure the engine's sensing units, circuitry harnesses, and installing points will match the truck.
The "Core Charge"
Most reliable engine sellers need a "core charge." This is a deposit paid at the time of purchase which is refunded when the buyer sends their old, damaged engine back to the seller. This allows remanufacturers to recycle the engine obstructs. For a heavy Cummins engine, shipping a core back can be costly, so buyers ought to inquire if the seller covers return freight.
Guarantee Terms
Not all guarantees are created equal. A buyer needs to look for:
- Nationwide Coverage: Ensures the engine can be repaired at any store if the truck breaks down while taking a trip.
- Labor Claims: Does the warranty pay the mechanic for the time invested changing a malfunctioning engine, or does it just supply the replacement part?
- Transferability: If the truck is sold, does the warranty pass to the new owner?
4. Checklist for Buying a Dodge Ram Engine
To enhance the process, purchasers ought to utilize a checklist to vet prospective suppliers and engines.
- Verify the Engine Code: Match the 8th digit of the VIN.
- Inquire about Testing: For used engines, request for compression test results or "run videos." For remanufactured engines, inquire about "sim-testing."
- Examine the Seller: Check online evaluations and BBB rankings of the engine supplier.
- Verify Shipping Details: Does the cost include property delivery or "liftgate" service?
- Identify Included Parts: Does the engine come "long block" (block and heads) or "brief block" (just the block)?
- Review the Core Return Policy: Understand the timeline and shipping costs for returning the old engine.
5. Prospective Installation Extras
When changing a Dodge Ram engine, it is seldom practically the engine itself. Typically, several auxiliary elements should be replaced concurrently to avoid old parts from harming the new financial investment.
- Water Pump and Thermostat: These are fairly low-cost and easier to install while the engine is out.
- Spark Plugs and Ignition Coils: Ensuring a fresh ignition system helps the brand-new engine run efficiently from the first day.
- Gaskets and Seals: Specifically, the rear main seal (if not already installed) and exhaust manifold gaskets.
- Fluids and Filters: New oil, coolant, and transmission fluid are compulsory.
6. Often Asked Questions (FAQ)
How much does it cost to change a Dodge Ram engine?
The expense varies substantially based on the engine type. A pre-owned 5.7 L HEMI might cost in between ₤ 2,500 and ₤ 4,500, while a remanufactured variation averages ₤ 4,000 to ₤ 6,000. Cummins diesel motor are significantly more pricey, typically varying from ₤ 7,000 to ₤ 12,000. Labor expenses typically add another ₤ 1,500 to ₤ 3,000.
What is the "HEMI Tick," and should I be fretted?
The "HEMI tick" is a common sound in 5.7 L and 6.4 L engines, frequently triggered by damaged manifold bolts or took lifter rollers that harm the camshaft. If buying a remanufactured engine, many home builders utilize upgraded materials and lifters to prevent this issue from recurring.
Is it much better to rebuild my current engine or buy a replacement?
Reconstructing an engine in your area can be lengthy and typically does not have the thorough service warranty of a massive remanufacturer. Buying a ready-to-install engine is typically faster and provides more predictable outcomes.
How long does it take to switch a RAM engine?
For a professional shop, a basic fuel engine swap takes between 15 and 25 labor hours. Diesel engines might take longer due to their weight and the complexity of the turbo and emissions systems.
Can I update to a bigger engine (e.g., V6 to V8)?
While possible, it is not suggested for many buyers. Swapping from a V6 to a V8 involves altering the transmission, circuitry harness, engine control module (ECM), and cooling system. It is usually more cost-efficient to purchase a truck that initially featured the bigger engine.
7. Conclusion
