68244577AA | Genuine Cummins® EGR Bypass Valve For Ram 2500, 3500 2013-24

• Pressure Relief

  • Prevents excessive pressure buildup in a system (e.g., cooling, lubrication, or intake).

  • Protects components like radiators, hoses, and filters from damage.

• Flow Regulation

  • Redirects fluid (coolant, oil, or exhaust gases) around a component when it’s not needed — for example, bypassing the EGR cooler when the engine is cold.

• System Efficiency

  • Improves warm-up times, maintains consistent flow and temperature, and reduces strain on pumps and valves.

1. Check Engine Light

• The check engine light may turn on.

• Common trouble codes relate to the EGR system flow or temperature.

2. Rough Idle or Engine Stalling

• The engine may idle unevenly, shake, or stall when stopped.

• Happens when exhaust gases aren’t flowing correctly.

3. Loss of Power / Poor Acceleration

• You may notice the vehicle feels sluggish, especially when accelerating.

4. Increased Fuel Consumption

• A malfunctioning valve can cause the engine to burn more fuel than normal.

5. Excessive Exhaust Smoke

• You might see black smoke from the exhaust (more common in diesel engines).

6. Engine Overheating or High Intake Temps

• Since the bypass valve helps regulate exhaust gas temperature, failure can lead to higher intake air temperatures.

7. Failed Emissions Test

• The vehicle may fail emissions testing due to improper exhaust gas recirculation.
