- Hydraulic Lifters: In some cases, the roller bearings in the lifters stop working, which can eventually harm the camshaft if not addressed.
Cummins Turbocharger Components
The 6.7 L Cummins utilizes a Variable Geometry Turbocharger. With time, soot can develop on the internal moving nozzle.
- Turbo Actuator: This is the electronic part that manages the turbo vanes. It is a typical point of failure that typically leads to decreased increase and "limp mode."
Cooling System Components
- Water Pumps: The 5.7 L Hemi has actually seen a number of iterations of water pumps. Leaks from the weep hole or bearing failure are the most typical factors for a total replacement.
- Thermostats: A stuck thermostat can cause a Ram to run too cold (decreasing performance) or too hot (running the risk of head gasket failure).
5. Performance and Heavy-Duty Upgrades
For those who utilize their Ram trucks for extreme towing or off-roading, stock parts may not always suffice. The aftermarket provides different "sturdy" options.
Top Performance Upgrades:
- Cold Air Intakes: These change the restrictive factory air box, enabling the engine to breathe much better and increasing throttle action.
- Upgraded Oil Catch Cans: Specifically for the Hemi, a catch can filters oil vapors from the PCV system before they go into the consumption manifold, keeping valves cleaner.
- High-Flow Exhaust Systems: Reducing backpressure enables the engine to expel gases quicker, which is especially advantageous for the Cummins under heavy load.
- Sturdy Radiators: Aluminum radiators with bigger cores offer remarkable heat dissipation compared to plastic-tank factory systems.
