Typical Ram Truck Engines

3.6 L Pentastar V6: The basic workhorse for numerous 1500 designs, known for balance and efficiency.
4.7 L PowerTech V8: Found in older designs (2000s), a long lasting overhead-cam style.
5.7 L HEMI V8: The most renowned Ram engine, including Variable Valve Timing (VVT) and Multi-Displacement Systems (MDS).
6.4 L HEMI V8: Found mostly in the 2500 and 3500 Heavy Duty trims.
5.9 L & & 6.7 L Cummins Turbo Diesel: The gold requirement for hauling and high-torque applications.

Essential Engine Parts Categories

When searching for Ram engine parts, categories are normally divided by their function within the internal combustion system. Understanding these categories helps buyers prioritize their spending.

1. The Ignition System

For gas engines (Pentastar and HEMI), the ignition system is crucial for fuel economy. The HEMI engine is special because it utilizes 2 spark plugs per cylinder (16 overall for the V8). When purchasing these parts, it is extremely recommended to stick with OEM (Original Equipment Manufacturer) Mopar or high-end brands like NGK or Bosch to avoid misfire codes.

2. The Cooling System

Ram trucks, especially those used for towing, create substantial heat. Replacing a used water pump, thermostat, or radiator pipes is a typical necessity as the automobile nears 100,000 miles. A failure in the cooling system can result in distorted cylinder heads, especially in the 4.7 L and 5.7 L engines.

3. Gaskets and Seals

A common problem understood to many Ram owners is the “HEMI Tick.” While this can in some cases be internal, it is frequently triggered by broken exhaust manifold bolts or stopped working manifold gaskets. Buying high-quality replacement gaskets and grade-8 steel bolts can supply a long-term repair to this typical nuisance.

Aftermarket Performance: Brands like S&B, Banks Power, or Edelbrock frequently provide parts that surpass OEM specs for power. If the objective is increased horsepower or torque, aftermarket is the method to go.
Aftermarket Economy: Budget brands found at regional big-box vehicle shops appropriate for non-critical components like air filters or certain cosmetic engine covers, though they might have much shorter life expectancies than OEM parts.

Critical Factors to Consider When Purchasing

Purchasing the wrong part not just wastes cash but can also result in mechanical failure. To guarantee the right fit, purchasers need to follow a stringent list.

Utilize the VIN (Vehicle Identification Number)

The VIN is the most precise method to source parts. Since Ram frequently updates mid-year (such as the 2019 “Classic” vs. “New Body Style”), the production date and VIN will define precisely which variation of a part is needed.

Checklist for Buying Ram Engine Parts:

Verify the Engine Displacement: (e.g., Is it a 5.7 L or a 6.4 L?)
Look For Core Charges: Many retailers need the old part (like an alternator or cylinder head) back to recycle; otherwise, they charge a “core fee.”
Inspect Part Ratings: For diesel engines, ensure filters satisfy the micron-rating requirements specified by Cummins.
Service warranty Terms: Ensure the seller offers a minimum of a 12-month guarantee on mechanical elements.
Try to find “Kits”: Often, it is more affordable to buy a “Water Pump Kit” that consists of the gasket and thermostat rather than buying them individually.

Often Asked Questions (FAQ)

Q: Why is my Ram 1500 making a ticking sound?A: This is frequently the “HEMI Tick.” It is normally triggered by damaged exhaust manifold bolts or, more seriously, a taken lifter roller that can harm the camshaft. If it is the latter, you will require to purchase a camshaft and lifter replacement kit.

Q: Can I utilize 5W-30 oil in my 5.7 L HEMI rather of 5W-20?A: It is not recommended. The Multi-Displacement System (MDS) in the HEMI counts on the specific viscosity of 5W-20 to run the solenoid-controlled lifters. Using the wrong oil can set off a Check Engine Light and prevent the engine from dropping into four-cylinder mode.

Q: How frequently should I change the fuel filters on a Cummins Ram?A: For the 6.7 L Cummins, it is commonly recommended to change both the front and rear fuel filters every 15,000 miles or every other oil change. Modern diesel injection systems are extremely conscious pollutants.

Q: Are performance air intakes worth the investment?A: For the Pentastar V6 and HEMI engines, a cold air intake can enhance throttle action and sound. On the Cummins diesel, the stock airbox is already extremely efficient, so performance gains are typically minimal unless the truck has actually been substantially “tuned.”

Q: Where can I discover my engine code?A: The engine code is generally located on a sticker label on the motorist's side valve cover or can be identified by the 8th digit of the Vehicle Identification Number (VIN).
