When to do EGR maintenance on a Cummins diesel?
When to do EGR maintenance on a Cummins diesel?
Ironically enough, most EGR-related issues surface after the 70,000-mile mark in most Ram pickups, so if this maintenance is performed at the appropriate time, much of the 6.7L Cummins’ EGR issues can be avoided. While EGR valve issues are much more common, EGR cooler failures do happen on 6.7L Cummins mills.
Are there any problems with the Dodge Ram 6.7 Cummins Engine?
Many also associate the Cummins name with some of the best light truck diesel engines ever. However, no engine is perfect and the 6.7 Cummins diesel is no exception. In this article, we discuss the most common problems on the Dodge Ram 6.7 Cummins engine as well as overall reliability.
Which is Cummins engine has the weakest EGR valve?
6.7L Cummins’ EGR Valve Although it’s known for being one of the most robust engines to ever grace the ¾-ton and 1-ton truck segment, even the 6.7L Cummins has its fair share of EGR gremlins. The weakest link in the 6.7L Cummins’ EGR system lies in its EGR valve.
Why does a diesel engine need an EGR cooler?
The gas circulated by the EGR system can be considerably hot however, especially in vehicles equipped with diesel engines. For this reason many diesel engines are equipped with EGR coolers to lower the temperature of the exhaust gases before they enter the engine.

Which is weakest link in Cummins EGR system?
The weakest link in the 6.7L Cummins’ EGR system lies in its EGR valve. The spring loaded, solenoid activated valve is prone to gumming up and sticking just like other valves used in the competition’s engines.
How does the EGR system work on a 6.7L diesel?
The EGR system on the 6.7L Power Stroke (’11-present) couples two floating EGR coolers into one housing. Their “floating” nature allows them to expand and contract without risk of cracking (as was the case on previous engines).
