That is why below, we explain each of these problems and provide some of the most suitable solutions. So, this is a great way to enjoy your full potential.
You can also learn about the main specifications and features of the Dodge RAM 3500 diesel.
05 Common 2012 Dodge Ram 3500 Diesel Problems
While it is possible to find a wide variety of problems with this vehicle, not all are truly common.
That is why here we have found some of the most common problems that users of this vehicle may encounter. We will also mention the solution to these Dodge Ram 3500 diesel problems.
Among the most frequent problems that the users of this vehicle usually suffer, we must mention in the first place the clogging that usually occurs in the diesel particulate filter.
Some particles easily clog this filter, and these particles are more easily generated in certain situations.
Incorporating the diesel exhaust fluid can generate advantages or disadvantages. This fluid is specially designed to reduce the emissions of this engine.
When this fluid is not used in the Dodge RAM 3500 diesel, the diesel particulate filter can become clogged due to the increased number of missions it has to deal with.
When clogs begin to appear in the diesel particulate filter and other parts of the engine, a high level of back pressure can easily be generated.
So, when the user encounters this problem, he may notice a higher workload for the engine and more heat generation.
02. Turbocharger failures
We can find a common problem with blockages, but failures in a turbocharger are an even more frequent problem.
This inconvenience can happen at any time, which may be due to the type of driving of each user of this vehicle.
During the whole process of this problem, the user will encounter some common symptoms.
So, the user can pay attention if the oil seals leak or the bearings are too worn out. In the latter case, the shaft may show shaft play.
Of course, turbochargers have a specific service life, so sooner or later, this will start to generate other problems.
Many users do not wait too long for the engine to reach the proper oil temperature. Hot turbo facts that get splashed with cold oil are an obvious problem of it all.
03. Cylinder head gasket damage
While this problem is not as common as the previous ones, it is something that users should be aware of nonetheless.
Mainly, these damages or problems appear due to the torque and power that this Dodge RAM model can generate, and the high-level pressures produced by the cylinders are one of the most important reasons.
Some symptoms appear when the cylinder head gasket starts to fail. One of the main problems is that the coolant can mix with the engine oil.
The opposite situation can also occur, which leads to excessive heating due to the mixing of these two liquids that work separately.
To all this can be added the appearance of smoke with a white hue and a curious, sweet smell. Once the head gasket melts, the combustion chamber will receive coolant.
In turn, this problem can be aggravated due to the high temperatures that will begin to be generated.
04. Inadequate fuel dilution
Some characteristics in the operation of the engine of this vehicle can produce a dilution of fuel in the engine oil.
The procedure that allows the diesel particulate filter to trap the particles generated in the combustion inside the engine must be considered.
In this way, the vehicle emits fewer polluting emissions.
According to what many experts have considered, this vehicle produces too much dilution. When this happens, the engine oil can lose some of its effectiveness.
Thus, the engine will have less protection and lubrication. As a result, the different parts of the engine will suffer accelerated wear.
05. Cooler Failures
When this vehicle has too high a mileage, the cooler can fail. The inconvenience of the extra equipment to deal with emissions that trucks have can lead to a few problems.
When this happens, it is also often the case that the EGR valve is also failing.
One of the most critical aspects of this situation is that this equipment cannot be removed.
Some states require drivers or owners of these vehicles to have this equipment about emissions laws.
2012 Dodge Ram 3500 diesel features & specifications
Many people often use the Dodge RAM 3500 for its features found under the hood.
So, we can find a 6 7 L diesel engine with six cylinders in line and turbocharged with the cylinder head and iron block. We can also highlight the power of 350 horsepower.
This engine also stands out for its torque power of 650 lb-ft with a manual transmission and 800 lb-ft with automatic transmission.
Along with that, we also find four valves per cylinder in the engine and a 6-speed manual transmission. Users can choose the 6-speed automatic transmission as an option.
Additionally, this vehicle provides electrically locking front and rear differentials and a ground clearance that exceeds several of its predecessor models.
So, these features make it an excellent vehicle for rough roads or off-road trails.
Also worth mentioning are the 4.56 axle ratio, Bilstein shock absorbers, and electronically disconnected anti-roll bar.
These features are also conducive to driving in rugged terrain, especially when transporting heavy loads.
On the outside, it is possible to find steel wheels with a 17-inch size as standard or the option of incorporating aluminum wheels of the same size.
Users can also utilize the adjustable towing mirrors along with the vehicle’s top-mounted running lights.
Safety features such as anti-lock brakes, backup camera, and rear parking assist are also included.
This is one of the vehicles that are part of the RAM HD pickups: the RAM 5 7 L V8 gasoline engine.
Some of these models incorporate significant changes, such as a steering wheel with a new design and auxiliary controls.
Finally, we can highlight the black bumpers and a new front grille design. Undoubtedly, this is one of the most reliable and efficient vehicles, especially for the durability and power of the engine.
Solutions for the 2012 Dodge Ram 3500 Diesel Problems
To save money by avoiding some of the problems mentioned above, we will also mention the most efficient solution in each case.
- Blockages: one of the most efficient solutions comes with washing diesel particulate filters, although some people decide to eliminate this filter definitively. Cleaning is a solution with a short useful life, but it can avoid fines in some States due to clogging or lack of this type of filter.
- Turbocharger failures: to avoid this problem, the user needs to wait for the engine oil to reach the proper temperature before accelerating the vehicle too much. It is recommended to replace the turbocharger, as this damaged part can damage other engine parts.
- Damage to the cylinder head gasket: to avoid replacing this part because it is somewhat costly, it is possible to apply an alternative solution. Fire rings and head studs can be optimized, preventing the head from lifting and starting to fail.
- Inadequate fuel dilution: there are two ways to avoid this drawback. The first is to allow the engine to reach the proper temperature, and the other way is to avoid too long idling.
- Cooler Failures: an efficient solution is the cleaning of this valve or the replacement of these parts. Removal of the EGR valve is not recommended, creating legal problems.
