Tools You'll Likely Need:
* Socket wrench set: Including deep sockets to reach the fan clutch nut.
* Wrench for the fan clutch: The size depends on your specific vehicle; some use a special fan clutch wrench.
* Socket and wrench for the fan shroud bolts: If applicable.
* Penetrating oil (PB Blaster, etc.): To loosen rusted or seized bolts.
* Gloves: To protect your hands.
* Jack and jack stands: Essential for safety – never work under a vehicle supported only by a jack.
* Possibly a puller: If the fan clutch is stubborn.
Procedure:
1. Safety First: Disconnect the negative battery cable. Raise the van securely using a jack and place it on jack stands.
2. Access: Locate the fan clutch assembly. It's usually on the front of the engine, attached to the water pump. You may need to remove the fan shroud (if your model has one) first; it's usually held on by a few bolts.
3. Penetrating Oil: Apply penetrating oil to the fan clutch nut and let it soak for at least 15-20 minutes. This will help loosen any corrosion.
4. Remove the Fan Shroud (if applicable): Remove the bolts securing the fan shroud to the radiator and remove the shroud.
5. Remove the Fan Clutch Nut: Use the correct size socket and wrench to remove the nut holding the fan clutch to the water pump. This nut can be very tight, so be prepared for a challenge. A breaker bar may be necessary. Consider using an impact wrench if you have one. Keep in mind that the fan will turn freely once the nut is loose, so be careful not to injure yourself.
6. Remove the Fan Clutch: Once the nut is off, the fan clutch should pull off the water pump. If it's stuck, you may need a puller to remove it safely.
7. Installation (Reverse Order): Install the new fan clutch in the reverse order of removal, ensuring the nut is properly tightened to the manufacturer's specifications (refer to your repair manual).
Important Considerations:
* Water Pump: Inspect the water pump while you have the fan clutch removed. If there's any play or leaks, you may want to replace it while you have access.
* Fan Blades: Be extremely careful when handling the fan blades; they are sharp and can cause injury.
* Torque Specifications: Use a torque wrench and adhere to the manufacturer's specifications for tightening the nut. Over-tightening can damage the water pump.
* Professional Help: If you are not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. This is not a simple task for inexperienced DIYers.
This is a general guide. Refer to a repair manual specific to your 1996 Dodge Ram Van's engine for detailed instructions, torque specifications, and diagrams. Improper installation can cause engine overheating and damage. Safety should always be your top priority.
