An Overview of Ram Engine Platforms
The Dodge Ram has actually used several engine architectures throughout the years. Each platform requires specific elements tailored to its fuel type and performance objectives.
The 5.7 L Hemi V8: Known for its hemispherical combustion chambers, this engine concentrates on high-output power and features innovations like the Multi-Displacement System (MDS) to enhance fuel economy.The 6.7 L Cummins Turbo Diesel: A staple of the durable lineup, this inline-six engine is commemorated for its massive torque and commercial-grade durability.The 3.6 L Pentastar V6: This engine functions as the base design for lots of light-duty Rams, providing a balance of performance and sufficient power for everyday tasks.Table 1: Comparative Specifications of Modern Ram EnginesFunction3.6 L Pentastar V65.7 L Hemi V86.7 L Cummins DieselFuel TypeGasFuelDieselConfiguration60-degree V690-degree V8Inline 6InductionNaturally AspiratedNaturally AspiratedTurbochargedHorse powerApproximate. 305 hpApprox. 395 hpApprox. 370-420 hpTorqueApproximate. 269 lb-ftApproximate. 410 lb-ftApprox. 850-1,075 lb-ftCrucial Internal Engine Components
The internal parts of a Ram engine are created to endure extreme thermal and mechanical stress. These parts form the rotating assembly and the valvetrain, converting combustion into movement.
1. Pistons and Connecting Rods
Pistons move vertically within the cylinder bores. In a Cummins diesel engine, these pistons are frequently crafted from sturdy aluminum alloys with reinforced ring lands to deal with the high compression ratios essential for diesel combustion. In Hemi engines, the pistons are developed to help with the "Hemi" flame front during ignition.
2. Camshafts and Lifters
The camshaft controls the opening and closing of the intake and exhaust valves. A common conversation point among 5.7 L Hemi owners is the "Hemi Tick," which is typically credited to the failure of the needle bearings in the roller lifters. When these lifters fail, they can damage the camshaft lobes, needing a substantial engine overhaul.
3. Crankshaft
The crankshaft is the foundation of the engine, transforming the direct movement of the pistons into rotational force. In the Cummins 6.7 L, the crankshaft is remarkably robust, created to handle the 1,000+ lb-ft of torque created in high-output models.
Fuel and Air Induction Parts
Performance and power are governed by how well an engine "breathes" and how specifically it is fueled.
Turbochargers (Diesel Specific)
The Cummins engine makes use of a Variable Geometry Turbocharger (VGT). Unlike a standard turbo, the VGT can change its internal vanes to enhance airflow throughout the whole RPM variety. This lowers turbo lag and can also function as an exhaust brake to help slow the vehicle throughout heavy towing.
Fuel Injectors
Modern Ram engines use high-pressure fuel injection systems.
Gas: Direct injection or port injection systems provide an exact mist of fuel.Diesel: Common-rail injection systems run at pressures surpassing 30,000 PSI. Blocked or dripping injectors can lead to "rough idling," lowered fuel economy, or even engine "runaway" in extreme diesel cases.Throttle Body and Air Intake
The throttle body manages the amount of air entering the engine. In time, carbon deposits can build up on the butterfly valve, triggering irregular idling. Lots of enthusiasts select to update to cold air intake systems to offer the engine with denser, cooler air for much better combustion.
The Cooling and Lubrication Systems
Heat is the primary opponent of engine durability. The cooling and lubrication systems operate in tandem to keep temperature levels steady and friction at a minimum.
Water Pumps and Thermostats
The water pump flows coolant through the engine block and radiator. Data reveal that water pump failure is more common in high-mileage 5.7 L Hemi engines. A stopping working pump often offers warning through a "weep hole" leakage or a grinding noise from the pulley bearing.
Oil Pumps and Coolers
The oil pump ensures that metal-to-metal contact is prevented by a thin movie of oil. The 3.6 L Pentastar engines are known for a particular problem regarding the oil filter real estate and cooler assembly; these plastic parts can break gradually, leading to oil leaks in the "valley" of the engine.

Modern Dodge Ram Engine Part Ram engines are handled by an Engine Control Module (ECM). This "brain" depends on numerous sensing units to make real-time modifications.
Oxygen (O2) Sensors: These keep track of exhaust gases to adjust the fuel-air mix.Crankshaft Position Sensor: This informs the ECM precisely where the engine remains in its rotation to time the stimulate or fuel pulse.MAP/MAF Sensors: These measure the pressure and mass of the air getting in the engine.Grid Heater (Diesel): Unlike gas engines that use stimulate plugs, the Cummins utilizes a grid heater in the consumption manifold to warm the incoming air for cold starts.Indications of Engine Part Wear and Failure
Acknowledging the signs of stopping working engine parts can save owners countless dollars in repair expenses. Mechanics suggest searching for the following:
Discolored Exhaust Smoke: Blue smoke suggests oil burning (often valve seals or piston rings), while white smoke in a gas engine typically suggests a head gasket leak (coolant).Knocking or Metallic Tapping: This can indicate rod bearing wear or the previously mentioned Hemi lifter problems.Loss of Power: Often an indication of a failing turbocharger, clogged fuel injectors, or a limited catalytic converter.Fluid Leaks: Puddles under the truck ought to be identified instantly. Pink/Red is normally coolant, while amber/black is engine oil.Necessary Tools for Under-the-Hood Work
For those planning to replace their own engine parts, certain tools are vital for the Ram platform:
OBD-II Scanner: Essential for reading diagnostic trouble codes (DTCs).Torque Wrench: Critical for ensuring head bolts and manifolds are tightened up to factory specifications.Fuel Line Disconnect Tool: Required for dealing with the Cummins fuel system.Deep Well Sockets: Specifically for reaching the deeply recessed spark plugs on the 5.7 L V8.Frequently Asked Questions (FAQ)
Q: Can I use aftermarket parts rather of OEM (Original Equipment Manufacturer) parts?A: While aftermarket parts are often less expensive, OEM parts are designed particularly to the producer's tolerances. For vital parts like sensing units, oil pumps, and internal gaskets, OEM is typically suggested to guarantee durability.

Q: Why does the 5.7 L Hemi require 16 spark plugs?A: The Hemi architecture utilizes two trigger plugs per cylinder to guarantee a more total and efficient burn of the fuel-air mixture, which minimizes emissions and increases power.

Q: How do I understand if my Cummins turbocharger is stopping working?A: Common signs consist of a loud whistling or "dentist drill" sound, a considerable drop in boost pressure on the gauge, and extreme black smoke from the exhaust under load.

Q: What triggers the "Hemi Tick"?A: It is most commonly triggered by broken exhaust manifold bolts or failing hydraulic lifters. If the sound disappears once the engine heats up, it is most likely the manifold; if it persists, it is most likely the lifters.

Q: Is the 3.6 L Pentastar engine reputable for heavy towing?A: While extremely dependable for daily driving and light transporting, the Pentastar is not created for the sturdy towing tasks that the Hemi or Cummins can deal with. Exceeding its towing capacity can result in early wear on the cooling system and transmission.
