  • On 4BT 3.9 /6BT 5.9 engines, look for the dataplate. The dataplate information is stored on a long, narrow metal tag affixed to the front cover/gear housing.

How can you tell a 5.9 cummins?

The Cummins 5.9 engine block’s cast number will be found immediately below the wiring harness and above where the oil pan meets the block. The surface of Tupy engine blocks has a two-digit number imprinted on it. Teksid’s blocks have a longer sequence of numbers in a smaller size.

How can you tell the difference between a 5.9 and 6.7 cummins?

When the 6.7 Cummins diesel first appeared in the 2007 Dodge Ram diesel pickups, it superseded the 5.9 Cummins diesel. The 6.7 engine had great hopes, as the 5.9 engine was known for its long-lasting performance and ability to resist high mileage. If the 5.9 was good, the 6.7 must be much better, right?

The core parts of the 5.9 Cummins were carried over to the 6.7 Cummins, which meant it was off to a good start because the 5.9 Cummins had a reputation for solid performance and a wide range of aftermarket parts and servicing.

The 6.7 Cummins comes with a comprehensive set of emissions control elements, the majority of which are not available on the 5.9 Cummins. An EGR (exhaust gas recirculation) system, a DOC (diesel oxidation catalyst), a NAC (NOx absorption catalyst), a DPF (diesel particulate filter), and, starting in 2013, an SCR (selective catalytic reduction) system are among these components (selective catalytic reduction). The SCR became standard in Cummins 6.7L engines after that.

Because of the EPA’s rigorous criteria, emissions control devices are required for modern diesel engines like the 6.7. Unfortunately, they do have an impact on performance.

The engine achieves a hotter combustion temperature without EGR, allowing it to burn fuel more thoroughly. This reduces particulate matter while increasing NOx output (Nitrogen Oxide). The issue with producing more NOx is that it causes excessive carbon buildup, which causes engine oil and coolant to degrade. The 5.9 did not have an EGR system, unlike the 6.7, and this likely contributed to its reputation for longevity, even with high miles on the engine.

In comparison to the 5.9 Cummins, the 6.7 Cummins produces a lot of torque at low RPM. This is due to the longer stroke in the 5.9 Cummins, which is 4.72 inches vs. 4.88 inches in the 6.7 Cummins.

Increased low-end torque translates to greater towing capability, so it’s easy to understand why this is a plus. However, it also implies that the cylinders will be under higher pressure. Head gasket failure, which is a typical problem on the 6.7 Cummins, can be caused by increased cylinder pressure. The 5.9 Cummins, on the other hand, experienced very few head gasket problems.

By 200,000 miles, a 6.7 Cummins that is regularly used to tow is likely to have head gasket troubles. Head gasket problems might occur considerably sooner in modified engines with performance enhancements. Another factor contributing to head gasket failure on the 6.7 Cummins is the smaller sealing gap between the water jackets and cylinders due to the bigger bore.

The fixed geometry turbo on the 5.9 Cummins varies from the variable geometry turbo on the 6.7 Cummins. With a 58mm compressor wheel, internal wastegate, and 58mm turbine wheel, the fixed geometry turbo on the 5.9 is a straightforward design. It has a reputation for being exceptionally sturdy and long-lasting as long as it does not receive a boost of 45 psi or higher on a regular basis.

However, because of the fixed shape design, you’ll most likely have low RPM turbo lag. There is no wastegate on the 6.7 Cummins turbo system, and the compressor wheel is 60mm in diameter. The turbine wheel’s exhaust flow varies, allowing the system to respond more quickly at lower speeds. There is no turbo latency, and it operates as well as a larger turbo unit at high RPMs.

To summarize, while the more basic 5.9 fixed geometry turbo is more reliable, the more complex 6.7 variable geometry turbo provides superior performance.

The Exhaust Brake is a significant reason why the Cummins 6.7 is such a strong towing machine. The exhaust brake is a device that produces a restriction in the exhaust system, resulting in significant backpressure, which reduces engine speed and provides additional braking. On this engine, using the exhaust brake at all times helps prevent the sticking turbo issue that is typical on these engines.

The 6.7 turbo system’s variable geometry design provides for forceful braking. This reduces the amount of wear on a truck’s standard brakes significantly. Braking ability is also an important part of towing ability.

Only part of the equation is being able to draw a large load. You must also be capable of stopping a heavy load. The variable geometry design’s aggressive exhaust braking capability provides for effective and powerful deceleration. As a result, the 6.7 Cummins-powered Rams are among the best in the hauling category.

The Bosch high-pressure common-rail fuel injection system is used in both the 5.9 and 6.7 Cummins engines. The injectors in the 6.7 Cummins, on the other hand, are rated for higher pressure and are specifically engineered to withstand it. They also use less electricity to operate.

Each injector in the 6.7 has been programmed to prevent them from switching between cylinders. On the other hand, the 5.9 Cummins engines allow for cylinder swapping. Injectors with a higher pressure allow for additional torque and power.

When an engine is running at high RPMs with full load, combustion duration is limited. The 6.7’s higher-pressure injectors pump fuel into the engine fast, resulting in maximum power.

In conclusion, the 6.7 Cummins outperforms the 5.9 Cummins in practically every category. It also emits less pollutants that are hazardous to the environment. The 5.9 Cummins, on the other hand, is a simpler piece of technology that provides near-unbeatable reliability, even in high-mileage trucks.

You can make an informed decision about whether you want to go with the latest diesel technology or remain with an older, but still highly durable engine now that you know the primary distinctions between the 5.9 and 6.7 Cummins engines. Whichever option you choose, ProSource offers the Cummins diesel components you need to get the most out of your truck’s performance and endurance.

What color is a Cummins engine?

Registered. Cummins uses beige, although I don’t believe it was utilized in the light duty. That would make sense if they were painted over, or if Dodge did it.

How can you tell the difference between a 24v and 12v cummins?

A 12v cummins turbo diesel will say “cummins turbo diesel” on a 94-02 with the original emblems on the doors, whereas a 24v will say “24v cummins turbo diesel.” Also, the 94-97 models had chrome door mirrors, indicating a 12v, whereas the 98 12v and 24v models all had black plastic mirrors.

Is my Cummins a 53 block?

A “53” casting number on the side of a Cummins “53” block can be used to identify it. The casting number is usually found on the passenger side, below the injection pump, while some #53 blocks have it near the front of the engine on the driver side.

To find out if a certain engine has a “A big wire harness should be fitted to the 53” block on the passenger side of the engine. If present, there will be a hole just below the oil filter mounting assembly and directly in front of the front turbo drain port in the block, just above where the oil pan joins the block “In the block, 53” is cast. The numbers will be approximately one inch tall.

What is a 3rd Gen Cummins?

The term “3rd Generation Cummins” applies to Dodge Cummins trucks produced from 2003 to 2009. The 5.9L 24v Cummins engine is still available, but it’s partnered with updated technologies and larger cabins, making this generation of Dodge Cummins diesel trucks one of the most sought of all diesels. The introduction of common rail technology and the new Mega Cab design are two of the most stunning 3rd Generation Cummins features. Later in this generation, the 6.7L Cummins engine was introduced, and it is still utilized in today’s 4th and 5th generation Ram Diesel trucks. Below is a complete list of 3rd Gen Cummins Specs as well as thorough information on what distinguishes this Dodge Cummins generation from the others.

rd Generation 5.9L Cummins Performance Specs

When the 3rd Gen Cummins trucks were debuted in 2003, they were a considerable improvement over the Dodge Cummins trucks that were released in 2002, even their high output variants couldn’t compare. Cummins trucks from the third generation produce 305 horsepower and 555 lb-ft of torque in 2003. When compared to the 2nd Gen high output model from 2002, that’s a difference of 60 horsepower and 50 lb-ft of torque. Not only did the 3rd Gen’s performance improve in terms of horsepower and torque, but it also improved in terms of fuel economy. The 3rd Generation Dodge Cummins trucks are also significantly quieter and cleaner than previous models.

High Pressure Common Rail Technology

The 3rd Generation Cummins was a watershed moment for both Ram vehicles and Cummins. The trucks now use high-pressure common rail fuel injection, which makes them more efficient than earlier models. Electronic control is used to operate this high-pressure common rail injection system. Fuel is delivered to the dependable CP3 injection pump through an electronic lift pump. The fuel is then pressurized by the CP3 fuel injection pump before being supplied to the fuel rail. The fuel rail then transfers fuel to the injectors as needed. Compared to prior mechanical fuel injection systems, this technology is significantly cleaner and more efficient. It allowed Cummins to retain their trucks EGR-free for a few more years, until the cleaner 6.7L Cummins engine was debuted in 2007. 5.

L 24V Fuel Upgrades

Other fuel modifications were required as part of the new common rail system. Before sending the gasoline off, the CP3 fuel injection pump was fitted to pressurize it. CP3 injection pumps are well-known for their dependability and long lifespan. The ECM has installed new injectors that are controlled by it. While these injectors were not as durable as prior mechanical models, they still lasted for many hundred thousand kilometers on average. The 5.9l Cummins injectors in the third generation have a few minor modifications. Eight-hole nozzles with a 143-degree angle are used in injectors on trucks made before 2004. The nozzles on the 2004.5-2007 have been redesigned to minimize emissions, and they only have five holes and spray at a 124 degree angle.

rd Gen Cummins Turbochargers in 5.9L Engines

On the 5.9L versions of the 3rd Gen Cummins, two separate turbochargers were employed. The Holset HE341CW turbocharger was debuted in 2003. This turbocharger has a fixed geometry design and an internal wastegate that is mechanically controlled. Cummins introduces a new turbocharger in 2004.5. It not only helped the Dodge Cummins pickup line reduce pollutants, but it also improved performance. The Holset HE351CW turbocharger is the name of this turbocharger. It, too, is a fixed geometry turbocharger, but unlike the HE341, the waste gate is electronically regulated.
