In case you are wondering – there are quite a few Cummins signature 600 problems.
While these may not be common, these issues do arise, which is why it is important to know the best ways to address or prevent these problems.
The Signature 600 is the very first truck engine with an advanced Electronic Control Module in it. This is why it is capable of having a high horsepower engine but with a minimal fuel cost involved.
This is why it can generate more power and support better productivity in the business. Many truck operators are in need of that extra power for enhancing vehicle productivity. This also allows them to meet competitive demands and make sure you are able to maintain a desirable speed with less requirements for shifting gears.
Learn more about the Cummins Signature 600 and some issues that people encounter with it. Let’s jump right into it.

What’s unique about the Cummins Signature 600 is that the engine combustion technology has been refined, which helps in promoting fuel efficiency. The rated power output is also impressive, considering how fuel economy remains just as good.
It boasts of electronic and mechanical features, which are responsible for the increased responsiveness of the engine. Thus, it allows for better fuel economy and performance. It is also worth noting that the dual-overhead and single-head cam system in the Signature 600 is even more outstanding.
There is the cam one that drives a high pressure injection system, which makes for enhanced power, improved fuel economy, and excellent throttle response. As for Cam two, it actuates the exhaust and intake valves, in addition to the interbrake engine brake. This is capable of generating as much as 600 retarding horsepower.
As for the two-piece pistons, made of the most durable alloys, they run in mid-stop cylinders, which reduce the risk of cavitation. Moreover, this design offers better tolerance to variations in the materials used in coolants.
Because of the compact and intelligent design of the Cummins Signature 600, this gets rid of various external parts. The open-nozzle type of injectors also deliver emissions and noise benefits and without any need for external plumbing.
Overall, the ECM of the Signature 600 manages the timing and fueling for the cylinders. They work in tandem with your vehicle’s injectors. There are four solenoids instead of the usual six, which are found in the fuel system module, which is adjacent to your fuel injection cam. With a smarter layout, this ensures a more compact injector package found directly in the heart of your combustion chambers.
As for the other impressive features of the Cummins Signature 600, the electronic controls have been reinvented and improved to reduce the undesirable consequences of parasitic losses. The controls can detect when the vehicle is heading uphill, and these are designed to turn accessories off including air compressors. Thus, you can get optimum power when needed.
Overall, the Signature 600 is intended to be a low maintenance engine that is capable of a long lifespan – over millions of miles. This is all possible with the advanced filtration and lube systems. So, you can have twice the miles between service maintenance intervals.
While these are all great, there are some Cummins Signature 600 problems to take note of. We talk more about these issues in the next section.
Cummins Signature 600 Problems
The Signature 600 is one great engine that runs efficiently without much problems at all. Apart from the usual regular maintenance, it should perform just as great even when it is at a million miles.
But some people complain about the reduced fuel efficiency of the engine as time goes by. For instance, it can use up a lot of fuel, particularly depending on the load you are pulling. Some folks say they have to top up on fuel every 2500 to as much as 3000 miles. But this also depends on how much they idle and the weight they pull.
The jakes on these engines also work quite well. In fact, a few people claim to still keep their original brake shoes in their truck and the engine pulls very well. Troubles are far fewer than with other engines, which is one of the big benefits that the Signature 600 offers.
Some engines have different HP and torque ratings, but with the Signature 600, it comes with 2050 feet per pound of torque. It is important to have your engine serviced regularly such as oil every 15,000 and then get the filters changed. Some folks even use additives in their fuel such as a low-sulphur one, and the power becomes noticeably better.
