Dodge Ram Fan Clutch Problems

The Dodge Ram is a truck that is known for its durability and power. However, even the most durable trucks can have problems, and one of the most common problems with the Dodge Ram is fan clutch problems. The fan clutch is responsible for regulating the speed of the engine’s cooling fans, and when it fails, the fans can run at full speed all the time, which can cause the engine to overheat.

Fan clutch replacement is not a difficult task, but it is important to make sure that you get a quality replacement part, as there are many inferior parts on the market.

If you own a Dodge Ram, you may have experienced problems with the fan clutch. The fan clutch is responsible for cooling the engine by circulating coolant through the radiator. If it fails, the engine can overheat, causing serious damage.

There are several symptoms of a failing fan clutch, including: -The engine overheating, even when driving at low speeds or idling -The temperature gauge needle moving into the red zone

-Smoke coming from under the hood -A burning smell coming from under the hood If you notice any of these symptoms, it’s important to take your truck to a mechanic as soon as possible.

They will be able to diagnose the problem and replace the fan clutch if necessary.

Dodge Ram Fan Clutch Problems


What are the Symptoms of a Faulty Fan Clutch?

A fan clutch is a thermostatic device that controls the engagement of a vehicle’s cooling fan. The fan clutch engages the fan when the engine is hot and disengages it when the engine is cool, saving wear on the engine and improving fuel economy. A faulty fan clutch can cause several problems.

The most common symptom of a faulty fan clutch is an overheating engine. If the fan clutch is not engaging properly, the engine will not be cooled efficiently and will overheat. Another symptom of a faulty fan clutch is poor fuel economy.

If the fan is running constantly, it will use more fuel than necessary. If you suspect your car has a faulty fan clutch, take it to a mechanic for diagnosis and repair.

What Causes Fan Clutch Failure?

A fan clutch is a type of thermal clutch that attaches the engine’s fan to the shaft. It is designed to engage and disengage the fan as needed in order to maintain optimal engine temperature. Over time, however, the fan clutch can fail, causing the fan to either spin constantly or not at all.

There are several reasons why a fan clutch might fail. The most common cause is simply wear and tear; over time, the friction material inside the clutch wears down and loses its effectiveness. In some cases, this can be caused by an oil leak; if oil gets onto the friction surfaces, it can act as a lubricant and accelerate wear.

Additionally, if the cooling system isn’t functioning properly – for example, if there’s a coolant leak – this can also lead to premature wear of the fan clutch. In other cases, failure of the fan clutch may be due to a manufacturing defect. For instance, some clutches use plastic parts which can break or warp under high temperatures; in these cases, replacement with a higher-quality aftermarket part may be necessary.

Additionally, poorly-made bearings or seals can also cause problems that lead to failure of the fan clutch. If your vehicle’sfan clutch has failed, it’s important to have it replaced as soon as possible.

How Do You Troubleshoot a Fan Clutch?

When it comes to troubleshooting a fan clutch, there are a few things you can do to narrow down the potential causes. First, start by checking the fluid level in the reservoir. If it’s low, then topping it off may solve the problem.

If the fluid level is fine, then next check the condition of the fan clutch itself. If it’s damaged or worn out, then replacing it will be necessary. Finally, if neither of those solutions fix the issue, then it’s likely that there is something wrong with the electrical system that controls the fan clutch.

What Happens When a Fan Clutch Stops Working?

When a fan clutch stops working, the engine will overheat. The fan clutch is what allows the fan to spin at different speeds, depending on the needs of the engine. If it stops working, the fan will only be able to spin at one speed, and that speed may not be enough to keep the engine cool.

Dodge Diesel Fan Clutch Problems

If you own a Dodge diesel truck, you may have experienced problems with the fan clutch. The fan clutch is responsible for cooling the engine by circulating air through the radiator. It is mounted on the front of the engine and is driven by the serpentine belt.

The fan clutch can fail in two ways: it can seize up, or it can fail to engage. If it seizes up, it will no longer be able to circulate air through the radiator, and your engine will overheat. If it fails to engage, then there will be insufficient airflow and your engine will also overheat.

There are several symptoms that can indicate a problem with the fan clutch: -the check engine light may come on -the temperature gauge may read higher than normal

Dodge Ram Fan Clutch Test

If your vehicle is equipped with a fan clutch, it’s important to know how to test it. A fan clutch is a thermal device that couples or decouples the engine cooling fan to the water pump shaft. When the engine is cold, the fan clutch engages the fan to help cool the engine.

As the engine warms up, the fluid in the fan clutch expands and disengages the fan. There are two ways to test a fan clutch: with a scanner or by feeler gauge. If you have access to a scanner, you can check for codes that may indicate an issue with the fan clutch.

If you don’t have a scanner, you can check the operation of the fan clutch by feeling how fast it spins when engaged. To test by feeler gauge: 1. With the engine off, engage the cooling fans and see how fast they spin.

2. Place your hand on top of one of the blades and try to stop it from spinning. If it’s difficult to stop, that means that there’s good engagement between the blade and hub assembly inside ofthefanclutch .

Dodge Ram Fan Clutch Noise

If you own a Dodge Ram, you may have noticed a strange noise coming from the engine area. This is called fan clutch noise and it’s caused by the fan clutch engaging and disengaging. The noise is most noticeable when the engine is cold, but it can also be heard when the engine is warm.

The good news is that this noise is not harmful to your truck and does not indicate a problem. The fan clutch is designed to engage when the engine temperature gets too high, so it’s normal for it to make noise as it engages and disengages. If you’re concerned about the noise, there are a few things you can do to reduce it.

First, make sure that your truck’s cooling system is in good working order. If the cooling system isn’t functioning properly, it could cause the fan clutch to engage more often than necessary, which will increase the noise level. Next, check the tension on the belt that drives the fan clutch.

If the belt is loose, it will cause the clutch to engage more frequently, which will again increase the noise level. Finally, if all else fails, you can always replace the fan clutch with a new one.

6.7 Cummins Fan Clutch Test

If you have a 6.7 Cummins, it’s important to know how to test the fan clutch. This is a simple process that can be done with a few tools. First, you’ll need to locate the fan clutch.

It’s located on the front of the engine, near the radiator. Once you’ve found it, you’ll need to remove the nut that holds it in place. This can be done with a wrench or socket set.

Once the nut is removed, you can pull the fan clutch off of the engine. Be careful not to damage any of the surrounding components while doing this. With the fan clutch removed, you can now inspect it for any damage or wear.

If everything looks good, you can reinstall the fan clutch and tighten down the nut. If there is any damage to the clutch, it will need to be replaced before being reinstalled.


If you’re a Dodge Ram owner, you may be having problems with your fan clutch. This can be a major problem, as it can cause your engine to overheat. There are a few different things that can cause this problem, and it’s important to know what they are so you can fix it.

Here are some of the most common causes of fan clutch problems in Dodge Rams: -Worn out bearings: The bearings in your fan clutch can wear out over time, causing the fan to wobble and not spin as efficiently. This can eventually lead to the fan seizing up entirely.

-Leaking fluid: If there is any sort of leak in the system that supplies fluid to the fan clutch, it will not work properly. This could be due to a bad seal or something else entirely. -Dirty fluid: If the fluid in the system becomes dirty, it will not lubricate the bearings properly and they will eventually fail.
