Tools You'll Need:
* New serpentine belt: Make sure you get the correct size and type for your van. Your auto parts store can help you find the right one if you provide your van's VIN.
* Wrench(es): Sizes will vary depending on the tensioner pulley. Probably a combination of metric and standard sizes.
* Socket wrench and ratchet: Helpful for reaching tight spots.
* Pliers (possibly): May be needed to help with some belt routing.
* Gloves: To protect your hands.
* Jack and jack stands (recommended): To safely lift the front of the van.
* Wheel chocks (recommended): For added safety.
* Shop rags or paper towels: To clean up any spilled fluids.
General Steps (Consult your repair manual for specifics):
1. Safety First: Park your van on a level surface, engage the parking brake, and use wheel chocks. Raise the front of the van using a jack and secure it with jack stands. Never work under a vehicle supported only by a jack.
2. Locate the Serpentine Belt and Tensioner: The serpentine belt runs around various pulleys (alternator, power steering pump, water pump, etc.). The tensioner is a pulley with a mechanism to release tension on the belt. It may be spring-loaded or have a bolt to loosen.
3. Release Belt Tension: This is the crucial step. The method varies. Common methods include:
* Tensioner Pulley Bolt: Loosen a bolt on the tensioner pulley using the appropriate wrench. This will allow you to move the tensioner, creating slack in the belt.
* Tensioner Lever: Some tensioners have a lever that can be moved to release tension. Consult your repair manual to determine how to operate this lever.
4. Remove the Old Belt: Once tension is released, carefully slip the belt off the pulleys. You may need to pry it slightly in some areas.
5. Install the New Belt: Carefully route the new belt around the pulleys in the same order as the old belt. Make sure it's seated properly on all pulleys. You can use a diagram from your repair manual or take a picture of the old belt routing before removing it.
6. Release Tensioner: Once the new belt is in place, slowly tighten the tensioner bolt (or release the tensioner lever) to apply tension to the belt.
7. Check Belt Alignment and Tension: Ensure the belt is properly seated on all the pulleys and that it's adequately tensioned. There's usually a specification for belt tension in your repair manual; otherwise, a slight deflection when pressed should be present.
8. Lower the Van: Carefully lower the van from the jack stands.
9. Test: Start the engine and listen for any squealing or unusual noises. Check for proper operation of all components driven by the belt (alternator, power steering, etc.).
Important Considerations:
* Difficult Access: Some components might be difficult to reach, requiring you to work in awkward positions.
* Proper Belt Routing: Incorrect routing can cause damage to the belt and driven components.
* Tension: Too little tension can cause slipping and premature belt failure, while too much tension can put extra stress on the bearings of the pulleys and the belt itself.
Again, refer to your vehicle's repair manual for detailed instructions and diagrams specific to your 1995 Ford van model. If you are not comfortable performing this repair yourself, it's best to take your van to a qualified mechanic. Working on a car without the proper knowledge can lead to damage or injury.
