Dodge Ram 5.9 Cummins engines come in two different varieties.
The 12-valve and 24-valve versions both have slight differences that give each their own benefits and drawbacks.
Though they may look the same on the outside, the internals of these engines is quite different.
In this blog post, we’ll be taking a look at the 12V vs 24V Cummins turbodiesel engines to help you make a decision on which one is right for you.
What is Cummins 12v?
The 12-valve Cummins is a 5.9L engine that was produced from 1989-to 1998.
It was quicker and more powerful than the earlier 6BT engine, but it didn’t have the same longevity. These engines were also known for being quite loud.
Another advantage of the 5.9L Cummins engine is its simplicity. The engine was designed in an era when there were no endless electronics or complicated air intake systems.
As a result, the 12-valve Cummins is easy to work on and repairs are generally less expensive.
The P7100 injection pump is used in Cummins 12v engines, which is said to be more dependable than the Bosch VP44 injection pump.
We just want to make sure that everyone understands. When it comes to the Cummins 12V vs 24V debate, both are very trustworthy turbodiesel motors. There is a minor gap between the earlier 12v units.
The Cummins 12v is a reliable engine, however, like all engines, it will require regular maintenance and occasional repairs.
The most common problem with the 12v is the fuel injectors, which can become worn out and cause the engine to run rough.
In addition, the turbocharger can also cause problems, as it can become clogged with debris and lose its efficiency.
However, these problems are relatively easy to fix, and most mechanics will be familiar with the 12v.
What is Cummins 24v?
The 24-valve Cummins is a 5.9L engine that was produced from 1998-to 2007.
It’s an updated version of the 12-valve engine and was available in the Dodge Ram 2500/3500 trucks.
This engine is quieter and more powerful than the 12-valve, and it has a longer lifespan.
The 5.9L Cummins engine is still a strong engine overall. Many enthusiasts give the older 12v a slight edge, however, the 24v has benefits as well. For one thing, in stock form, it produces greater output.
This is an advantage for individuals who don’t want to modify or upgrade the 5.9 Cummins engine. The 24v Cummins is also a more recent motor and truck in general.
They offer additional features, better interior quality, and so on.
Keep in mind that the 24v was only available for a few years, so they can be more difficult to find and parts may be more expensive.
Overall, designed for durability and performance, the 24v engine is available in a wide range of horsepower options, making it a good choice for a variety of applications.
In terms of reliability, the 24v engine has a proven track record, with many owners reporting years of trouble-free operation.
12V vs 24V Cummins Difference
The main differences between these two engines are the number of valves, fuel delivery, and turbocharger.
The 12-valve has two valves per cylinder, while the 24-valve has four valves per cylinder.
The 12-valve uses a mechanically governed Bosch injection pump, while the 24-valve uses an electronically controlled unit injector system.
Lastly, the 12-valve has a single turbocharger, while the 24-valve has two turbochargers.
Which One is Better?
Cummins is a world leader in the design and manufacture of diesel engines.
Cummins as a company offers excellent customer support, with a team of factory-trained technicians available to help with any problems that may arise.
When it comes to 12v and 24v models, these are the most popular options for heavy-duty trucks.
If you want an engine that is powerful and quick, then the 12-valve is the way to go.
However, if you want an engine that is more reliable and longer-lasting, then the 24-valve is the better choice.
