MOST COMMON PROBLEMS OF DODGE / RAM 2004.5-2007 5.9L 24V

Don’t Let Diesel Engine Failures Ruin Your Day: ABCO Diesel Inc. Is Here to Help

We know how stressful it is when the engine in your truck breaks down, especially if you need it for work or everyday jobs. The Dodge/Ram 5.9L Cummins diesel engine from 2004.5 to 2007 is strong, but it has some common problems that can make you doubt how reliable your car is. From problems with the fuel system to broken pumps, these can ruin your day and leave you stuck. No need to worry, though—ABCO Diesel Inc. knows how to get your truck back on the road quickly and correctly.

Common Problems with the Dodge/Ram 5.9L Diesel Engine and How to Identify Them:

Fuel System Issues

The common-rail fuel system in the Dodge/Ram 5.9L Cummins is known for its sensitivity to contamination. Over time, dirt or water can find its way into the system, leading to poor performance and starting issues. Symptoms include rough running, smoke from the exhaust, and fuel mixing with engine oil, usually becoming noticeable around the 150,000-mile mark. To prevent these problems, regular maintenance and fuel filter changes are essential.

Pump Problems

Pump failures, particularly with the lift pump, are another frequent issue. Early models had an electric lift pump on the engine block, while later models moved it to the fuel tank. However, both designs can fail. If you notice a loss of power or engine stalling, it may be time to upgrade to a more reliable aftermarket lift pump, like the FASS Titanium Signature Series, which offers better filtration and performance.

Fuel Pressure Relief Valve Failures

Over time, the fuel pressure relief valve can fail, often due to dirt or a weakened spring. When this happens, low fuel pressure can result, leading to symptoms similar to other fuel system issues. If you notice rough idling or starting problems, a quick and affordable replacement of the valve can resolve the issue.

Maintaining Reliability

While the 5.9L Cummins engine is renowned for its durability, heat buildup can become a concern, especially in the rear cylinders. A coolant bypass kit can help manage temperatures and prolong the lifespan of critical engine components.
