Where is the fan clutch on a Dodge truck?
Locate the fan clutch on the front of the motor. It is held on by six 1/2-inch bolts on Dodge trucks. Check the bolts to make sure that they are all fastened tightly. Use the ratchet and socket to tighten if necessary. Check the electrical connection at the base of the fan clutch. Use both hands and pull the connectors apart.
What should I do if my fan clutch is going bad?
Silicone fluid leaking from the fan clutch would cause this problem. When the engine is off, there are a few things you can do to check the fan clutch: Spin the fan. Electronic types might freewheel, but most fan clutches should spin with a little effort.
How can you tell when a fan clutch is engaged?
You should be able to audibly detect when the fan clutch engages, with an accompanying rush of air. At idle, as engine temperature increases, a thermal fan clutch will engage at a certain temperature. Torque-limiting fan clutches will disengage at a certain engine speed. Alternatively, an optical tachometer can be used to measure fan speed.
What are the different types of fan clutches?
Types of Fan Clutches. The main types are non-thermal, thermal, and electronic — all of which use a silicone fluid to engage and disengage your fan. Non-thermal clutches operate solely based on the shaft speed of the water pump. At low and idling speeds, the clutch allows the fan blade to turn at almost a 1:1 ratio.

What are the symptoms of a bad or failing fan clutch?
As the fan clutch is a cooling system component, any issues with it can cause overheating and other issues. Usually a bad or failing fan clutch will produce a few symptoms that can alert the driver of a potential issue.
What kind of fan clutch does a Cummins diesel use?
I ran into a similar problem and the only fan clutch that would work properly was the oem mopar fan clutch, I replaced it twice with aftermarkets and the temp would get hot sometimes as you describe, especially after a good hard run then coming to an idle it would get warm, also the a/c would never blow cold at idle speed.
What causes oil to come out of a fan clutch?
Run your finger along the edges of the bearing seal on the backside of the fan clutch. If it comes away with a heavy coating of oil, the culprit is either a crack or a faulty seal. Radial streaks are another potential clue—this happens when oil escapes from the clutch and is then blown outward in all directions by the fan.
Why does a Dodge truck have a viscous fan clutch?
The viscous fan clutch provides proper system cooling and prevents compressor clutch slippage or burning, as well as premature compressor failure. Dodge diesel trucks, as well as most other diesels models, are designed with large cooling system. These systems operate at idle for long periods of time.

What is an electric fan clutch?
The fan clutch is a cooling system component that controls the operation of the engine cooling fans. While many newer vehicles now use electric cooling fans to keep the engine cool, many older vehicles used a mechanical fan clutch to control the fans.
Why is my Cummins fan clutch not working?
Using your air conditioner, however, causes wear and tear on the fan clutch as well as other parts of the Cummins motor. The fan clutch is an electronically controlled part that attaches to the fan on the front of your motor, and causes air to be forced into the Cummins’ A/C system.
Do you need DRB to test fan Cluch?
If the connector has not come apart or damaged or if the above statement has not been exceeded then a more in depth search will be required and you will need a decent DRB to test it. Oh yeah I can stop the fan! I better order one any good suppliers out there?
