The Ultimate Guide to Buying a Dodge Ram Truck Engine: Everything You Need to Know

For years, the Ram truck-- formerly the Dodge Ram-- has stood as a titan of American engineering. Understood for its rugged ability, carrying power, and distinct styling, a Ram truck is frequently a long-lasting companion for its owner. However, even the most durable machines reach a point where the heart of the automobile-- the engine-- starts to fail. Whether it is due to high mileage, catastrophic mechanical failure, or a desire for an efficiency upgrade, buying a replacement engine is a substantial investment.

This guide provides a detailed overview for those wanting to buy a Dodge Ram truck engine, covering the types of engines available, the differences between reaching for brand-new versus used, and the technical requirements needed to make an informed decision.


Comprehending the Ram Engine Lineup

Before proceeding with a purchase, it is vital to comprehend which engine belongs in which generation of the Ram truck. Over the years, Chrysler (and subsequently Stellantis) has 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 iconic engine connected with the Ram 1500. Since its reintroduction in 2003, it has actually become associated with "Mopar" power. It features a hemispherical combustion chamber that enables for better air flow and greater pressure, leading to outstanding 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. Understood for Dodge Ram Engine USA and huge torque output, it is the favored choice for heavy towing and business work.

3. The 3.6 L Pentastar ™ V6

Introduced as a more fuel-efficient option for the light-duty Ram 1500, the Pentastar V6 utilizes variable valve timing (VVT) to balance power and economy. It is an excellent choice for chauffeurs who utilize their trucks as day-to-day commuters rather than sturdy workhorses.

4. The 4.7 L Magnum V8

Found frequently in older 2000s designs, the 4.7 L Magnum was a precursor to the prevalent usage of the 5.7 L HEMI. While less effective, many of these trucks remain on the roadway, producing a consistent demand for replacement Magnum engines.

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

One of the most important decisions in the purchasing procedure is the "condition" classification of the engine. Each features its own set of pros and cons concerning expense and reliability.

New Engines (Crate Engines)

Buying a brand-new "crate" engine straight from Mopar or authorized dealers guarantees that every element is fresh from the factory.

  • Pros: Maximum life expectancy, absolutely no miles, comprehensive factory warranty.
  • Cons: The most expensive choice; might go beyond the overall market price of an older truck.

Remanufactured Engines

A remanufactured engine is a used engine that has actually been completely dismantled, cleaned up, and checked. Any used parts are replaced with brand-new components, and the engine is machined to meet original equipment maker (OEM) specs.

  • Pros: Often indistinguishable from brand-new performance-wise, usually consists of a multi-year warranty, more inexpensive than new.
  • Cons: Quality depends greatly on the company doing the remanufacturing.

Utilized Engines (Recycled)

These are pulled straight from donor vehicles-- typically trucks that were associated with mishaps however had operating engines.

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

Vital Checklist Before You Buy

To guarantee a smooth deal and prevent the purchase of an incompatible motor, follow this vital checklist.

  1. Confirm the VIN (Vehicle Identification Number): The 8th digit of your VIN is the engine code. Constantly offer this to the seller to make sure the displacement and setup match your truck's computer system.
  2. Look for "Long Block" vs. "Short Block":
    • A Short Block includes the block, crankshaft, pistons, and linking rods.
    • A Long Block includes everything in the short block plus the cylinder heads, camshaft, and valvetrain. Many purchasers prefer a Long Block for an easier setup.
  3. Verify the "Core Charge": Most sellers need you to send back your old, broken engine (the "core"). If you do not, you will likely be charged a core fee varying from ₤ 500 to ₤ 2,000.
  4. Examine the Warranty Terms: Does the service warranty cover labor costs if the replacement engine fails, or just the parts? This is a crucial distinction for those paying a mechanic for setup.

Warning Signs That You Need a New Engine

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

  • The "HEMI Tick": While sometimes just a manifold bolt issue, a loud, consistent metal ticking can signify lifter failure and camshaft damage.
  • Extreme Oil Consumption: If the engine is burning through quarts of oil without a visible leakage, the piston rings or valve seals are most likely failing.
  • Metal Shavings in Oil: Finding "glitter" or metal flakes throughout an oil change shows that internal bearings are breaking down.
  • Coolant in the Oil: A milky "chocolate milk" look on the dipstick suggests a cracked block or a blown head gasket.

Can I swap a V6 for a V8 HEMI?

While a "HEMI swap" is physically possible, it is technically complex. It requires not only the engine but likewise a brand-new transmission, wiring harness, engine control module (ECM), and cooling system parts. It is generally more economical to sell the V6 truck and purchase a V8-equipped model.

How long do Cummins engines generally last?

With proper maintenance, a 6.7 L Cummins engine can last 300,000 to 500,000 miles. In contrast, a gas 5.7 L HEMI usually lasts in between 200,000 and 250,000 miles before requiring considerable overhaul.

Is the 5.7 L HEMI a trustworthy engine?

Yes, it is thought about one of the most dependable V8s on the marketplace. However, it is sensitive to oil change periods. Using the wrong viscosity or overlooking oil modifications can result in early wear of the Multi-Displacement System (MDS) lifters.


Purchasing a replacement engine for a Dodge Ram is a significant endeavor, however it is typically the most logical path to extending the life of a relied on automobile.
