The Ultimate Guide to Buying a Dodge Ram Replacement Engine
The Dodge Ram, now expertly understood simply as the RAM truck, has strengthened its location as a cornerstone of American automotive engineering. Understood for its rugged durability and substantial towing capability, these trucks are typically driven for numerous countless miles. However, even the most robust powertrains ultimately catch use and tear, high mileage, or mechanical failure. When a RAM owner faces a disastrous engine concern, the choice frequently boils down to 2 options: acquire a brand-new car or change the engine.
Offered the skyrocketing rates of modern pickup trucks, changing the engine is frequently the more economically sound decision. This guide supplies a thorough expedition of how to navigate the process of purchasing a Dodge Ram engine, covering the types of engines offered, sourcing choices, and vital technical factors to consider.
1. Understanding the Popular Dodge Ram Engine Options
Before looking for a replacement, it is important to identify exactly which engine powers the lorry. Dodge has used a range of powertrains over the decades, varying from fuel-efficient V6s to sturdy Cummins diesels.
The 5.7 L HEMI V8
Perhaps the most renowned engine in the RAM lineup is the 5.7 L HEMI. Famous for its hemispherical combustion chambers, this engine supplies a blend of horse power and torque that attract both everyday chauffeurs and those who utilize their trucks for light-to-medium towing. Buyers should know particular models, such as those featuring Multi-Displacement Systems (MDS) or Variable Valve Timing (VVT).
The 6.7 L Cummins Turbo Diesel
For heavy-duty RAM 2500 and 3500 designs, the Cummins inline-six diesel engine is the gold requirement. Known for extreme longevity and enormous torque output, replacing one of these engines is a substantial financial investment but can include another years or more to the truck's operational life.
The 3.6 L Pentastar V6
Found in many late-model RAM 1500s, this engine is created for fuel efficiency and reliability. While it does not have the raw power of the V8 or Diesel, it is a popular option for fleet cars and commuters.
Technical Comparison Table
The following table highlights the requirements of the most common engines found in the Dodge Ram lineup over the last years.
| Engine Type | Displacement | Setup | Horse Power (Approx.) | Torque (lb-ft) | Fuel Type |
|---|---|---|---|---|---|
| Pentastar | 3.6 L | V6 | 305 hp | 269 lb-ft | Gasoline |
| HEMI | 5.7 L | V8 | 395 hp | 410 lb-ft | Fuel |
| HEMI (Heavy Duty) | 6.4 L | V8 | 410 hp | 429 lb-ft | Gas |
| 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. Selecting the Right Replacement Category
When aiming to buy a Dodge Ram engine, the buyer needs to choose in between three main classifications: New (Crate), Remanufactured, or Used. Each has its own set of advantages and disadvantages.
New (Crate) Engines
A "dog crate engine" is a new engine manufactured by Mopar (the parts division for RAM). This is the most costly route however uses the highest level of security.
- Pros: Zero miles, complete maker service warranty, factory-fresh elements.
- Cons: Extremely high rate point, may go beyond the worth of an older truck.
Remanufactured Engines
Remanufactured engines are often thought about the "sweet area" for most RAM owners. These engines are disrobed to the block, cleaned up, and rebuilt with new or machined parts to fulfill or exceed initial devices manufacturer (OEM) specifications.
- Pros: Corrects understood factory flaws (like the "HEMI tick"), consists of a warranty (often 3 years/100,000 miles), and is substantially less expensive than a new engine.
- Cons: Quality depends heavily on the reputation of the remanufacturer.
Utilized Engines
Sourced from salvage lawns or donor vehicles, used engines are the most economical alternative.
- Pros: Lowest cost, typically includes devices like the alternator or consumption manifold.
- Cons: High threat, minimal or no service warranty, unknown maintenance history.
3. Secret Factors to Consider Before Purchase
Buying an engine is an intricate transaction. To ensure compatibility and longevity, a number of factors must be validated before any cash modifications hands.
The VIN Check
The Vehicle Identification Number (VIN) is the most reputable way to determine the appropriate engine. The 8th digit of a RAM's VIN specifically denotes the engine code. When interacting with sellers, offering the VIN ensures the engine's sensors, circuitry harnesses, and installing points will match the truck.
The "Core Charge"
Most trusted engine sellers require a "core charge." learn more is a deposit paid at the time of purchase which is refunded as soon as the buyer sends their old, broken engine back to the seller. This allows remanufacturers to recycle the engine obstructs. For a heavy Cummins engine, delivering a core back can be expensive, so purchasers should inquire if the seller covers return freight.
Warranty Terms
Not all service warranties are produced equivalent. A buyer must search for:
- Nationwide Coverage: Ensures the engine can be fixed at any store if the truck breaks down while taking a trip.
- Labor Claims: Does the warranty pay the mechanic for the time spent replacing a faulty engine, or does it just offer the replacement part?
- Transferability: If the truck is sold, does the guarantee pass to the brand-new owner?
4. Checklist for Buying a Dodge Ram Engine
To simplify the procedure, purchasers should use a list to vet potential suppliers and engines.
- Confirm the Engine Code: Match the 8th digit of the VIN.
- Inquire about Testing: For used engines, ask for compression test results or "run videos." For remanufactured engines, inquire about "sim-testing."
- Evaluate the Seller: Check online evaluations and BBB ratings of the engine provider.
- Verify Shipping Details: Does the cost include residential shipment or "liftgate" service?
- Determine Included Parts: Does the engine come "long block" (block and heads) or "brief block" (simply the block)?
- Evaluation the Core Return Policy: Understand the timeline and shipping expenses for returning the old engine.
5. Possible Installation Extras
When replacing a Dodge Ram engine, it is hardly ever just about the engine itself. Normally, numerous auxiliary components ought to be replaced all at once to avoid old parts from damaging the brand-new investment.
- Water Pump and Thermostat: These are reasonably affordable and easier to set up while the engine is out.
- Stimulate Plugs and Ignition Coils: Ensuring a fresh ignition system assists the brand-new engine run smoothly from the first day.
- Gaskets and Seals: Specifically, the rear primary seal (if not already installed) and exhaust manifold gaskets.
- Fluids and Filters: New oil, coolant, and transmission fluid are obligatory.
6. Frequently Asked Questions (FAQ)
How much does it cost to change a Dodge Ram engine?
The cost varies substantially based upon the engine type. A pre-owned 5.7 L HEMI may cost between ₤ 2,500 and ₤ 4,500, while a remanufactured version averages ₤ 4,000 to ₤ 6,000. Cummins diesel engines are significantly more costly, often varying from ₤ 7,000 to ₤ 12,000. Labor costs generally include another ₤ 1,500 to ₤ 3,000.
What is the "HEMI Tick," and should I be fretted?
The "HEMI tick" is a typical noise in 5.7 L and 6.4 L engines, often triggered by broken manifold bolts or took lifter rollers that harm the camshaft. If purchasing a remanufactured engine, lots of contractors utilize upgraded products and lifters to prevent this issue from repeating.
Is it much better to rebuild my current engine or purchase a replacement?
Restoring an engine in your area can be lengthy and frequently does not have the thorough warranty of a massive remanufacturer. Buying a ready-to-install engine is usually faster and offers more predictable results.
How long does it require to switch a RAM engine?
For an expert shop, a basic gasoline engine swap takes between 15 and 25 labor hours. Diesel engines may take longer due to their weight and the intricacy 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 purchasers. Switching from a V6 to a V8 includes changing the transmission, circuitry harness, engine control module (ECM), and cooling system. It is almost always more cost-efficient to purchase a truck that originally came with the bigger engine.
7. Conclusion
Buying a replacement engine for a Dodge Ram is a considerable endeavor, however it is one that can breathe brand-new life into a trusted lorry. By understanding the distinctions between new, remanufactured, and utilized systems, and by carefully confirming compatibility through the VIN, truck owners can avoid typical pitfalls.
