Comprehending the Ram Engine Lineup

Before proceeding with a purchase, it is crucial to understand which engine belongs in which generation of the Ram truck. Throughout the years, Chrysler (and subsequently Stellantis) has actually refined its lineup to include high-displacement V8s, fuel-efficient V6s, and world-renowned diesel powerhouses.

1. The Legendary 5.7 L HEMI ® V8

The HEMI is possibly the most renowned engine associated with the Ram 1500. Given that its reintroduction in 2003, it has actually become associated with "Mopar" power. It includes a hemispherical combustion chamber that enables much better airflow and higher pressure, resulting in excellent horse power and torque.

2. The 6.7 L Cummins ® Turbo Diesel

For those who own a Ram 2500 or 3500 Heavy Duty, the Cummins engine is the gold requirement. Known for its severe longevity and massive torque output, it is the preferred option for heavy towing and business work.

3. The 3.6 L Pentastar ™ V6

New, Remanufactured, or Used: Which is Right for You?

One of the most crucial choices in the buying procedure is the "condition" category of the engine. Each includes its own set of pros and cons regarding cost and dependability.

New Engines (Crate Engines)

Buying a new "cage" engine directly from Mopar or licensed dealers guarantees that every part is fresh from the factory.

  • Pros: Maximum life-span, absolutely no miles, detailed factory warranty.
  • Cons: The most expensive option; might surpass the total market price of an older truck.

Remanufactured Engines

A remanufactured engine is an utilized engine that has actually been totally taken apart, cleaned, and examined.  read more  are changed with brand-new elements, and the engine is machined to meet original equipment producer (OEM) specs.

  • Pros: Often identical from brand-new performance-wise, generally includes a multi-year service warranty, more inexpensive than new.
  • Cons: Quality depends heavily on the business doing the remanufacturing.

Utilized Engines (Recycled)

These are pulled directly from donor cars-- normally trucks that were associated with accidents but had functioning engines.

  • Pros: The least expensive method to get a truck back on the road.
  • Cons: Unknown history, limited warranty (frequently 30-- 90 days), threat of undiagnosed internal wear.

Necessary Checklist Before You Buy

To ensure a smooth transaction and avoid the purchase of an incompatible motor, follow this vital list.

  1. Verify the VIN (Vehicle Identification Number): The 8th digit of your VIN is the engine code. Always supply this to the seller to ensure the displacement and setup match your truck's computer system.
  2. Look for "Long Block" vs. "Short Block":
  • A Short Block consists of the block, crankshaft, pistons, and connecting rods.
  • A Long Block consists of everything in the brief block plus the cylinder heads, camshaft, and valvetrain. Most buyers choose a Long Block for an easier setup.
  1. Verify the "Core Charge": Most sellers require you to send back your old, damaged engine (the "core"). If you do not, you will likely be charged a core charge varying from ₤ 500 to ₤ 2,000.
  2. Check the Warranty Terms: Does the guarantee cover labor costs if the replacement engine stops working, or just the parts? This is a vital distinction for those paying a mechanic for setup.
  3. Evaluation Maintenance Records: If purchasing a used engine, ask for the CARFAX of the donor vehicle or evidence of oil modifications.

Indication That You Need a New Engine

Before committing to a multi-thousand-dollar purchase, ensure your present engine can not be saved by easier repairs. Common indications that a Ram engine is beyond repair work include:

  • The "HEMI Tick": While in some cases just a manifold bolt concern, a loud, consistent metal ticking can symbolize lifter failure and camshaft damage.
  • Excessive Oil Consumption: If the engine is burning through quarts of oil without a noticeable leak, the piston rings or valve seals are likely stopping working.
  • Metal Shavings in Oil: Finding "shine" or metal flakes during an oil change indicates that internal bearings are disintegrating.
  • Coolant in the Oil: A milky "chocolate milk" appearance on the dipstick suggests a split block or a blown head gasket.

Frequently Asked Questions (FAQ)

How much does it cost to change a Dodge Ram engine?

Depending on the year and engine type, costs generally vary from ₤ 4,000 to ₤ 12,000. A secondhand 4.7 L engine might be on the lower end, while a remanufactured 6.7 L Cummins diesel can quickly exceed ₤ 10,000 for the unit alone. Labor costs generally add another ₤ 1,500 to ₤ 3,000.

Can I swap a V6 for a V8 HEMI?

While a "HEMI swap" is physically possible, it is technically complicated. It requires not just the engine but also a new transmission, electrical wiring harness, engine control module (ECM), and cooling system parts. It is practically always more cost-efficient to offer the V6 truck and purchase a V8-equipped design.

How long do Cummins engines typically last?

With appropriate maintenance, a 6.7 L Cummins engine can last 300,000 to 500,000 miles. On the other hand, a gasoline 5.7 L HEMI normally lasts in between 200,000 and 250,000 miles before requiring significant overhaul.

Is the 5.7 L HEMI a trusted engine?

Yes, it is considered one of the most trustworthy V8s on the market. However, it is delicate to oil change periods. Utilizing the wrong viscosity or overlooking oil changes can cause premature wear of the Multi-Displacement System (MDS) lifters.


Purchasing a replacement engine for a Dodge Ram is a major endeavor, however it is typically the most logical path to extending the life of a relied on lorry. By understanding the requirements of your specific model, weighing the advantages of remanufactured systems versus used ones, and carrying out due diligence on service warranties and VIN compatibility, you can ensure your Ram truck remains on the road for several years to come. Whether you are seeking the raw power of the HEMI or the legendary endurance of a Cummins, the ideal engine is out there to assist you complete the task.
