Tools You'll Need:
* A wrench: Likely a 10mm or 13mm wrench or socket, but you need to check the nut size on *your* specific vehicle. Inspect it before you start to save time.
* Penetrating oil (optional): If the nut is particularly stubborn.
* Gloves (recommended): To protect your hands.
* Rag or cloth: To clean up any dirt or grime.
* New wiper arms: Make sure you purchase the correct ones for your 1992 Dodge Caravan.
Steps:
1. Prepare the Vehicle: Park your van on a level surface, engage the parking brake, and turn off the engine. It's best to do this on a warm, dry day.
2. Locate the Wiper Arm Nut: The wiper arm is attached to the wiper transmission arm by a nut. You'll need to locate this nut. It's usually visible, but might be covered in a small amount of grime.
3. Apply Penetrating Oil (Optional): If the nut looks rusty or difficult to turn, spray some penetrating oil on it and let it sit for a few minutes to help loosen it up.
4. Remove the Nut: Use the appropriate wrench to carefully remove the nut holding the wiper arm to the transmission arm. Hold the wiper arm firmly to prevent it from spinning while you loosen the nut.
5. Remove the Wiper Arm: Once the nut is removed, the wiper arm should come off. Sometimes, they might be stubborn. If it's stuck, gently wiggle and pull it. Avoid using excessive force that could damage the wiper transmission. There might be a small amount of play before it comes off.
6. Install the New Wiper Arm: Carefully align the new wiper arm with the wiper transmission arm. Make sure it sits correctly.
7. Secure the Wiper Arm: Replace the nut and tighten it securely, but don't overtighten. Overtightening can damage the arm or the transmission.
8. Repeat for the Other Wiper Arm: Repeat steps 2-7 for the other wiper arm.
9. Test the Wipers: Turn on your wipers to ensure they are working correctly and that the new arms are securely attached.
Important Considerations:
* Nut Size: The size of the nut holding the wiper arm can vary slightly. Make sure you have the correct wrench size before you start.
* Stubborn Arms: If the wiper arm is extremely difficult to remove, you may need to use a wiper arm puller tool, available at most auto parts stores. This specialized tool prevents damage to the wiper arm or the transmission.
* Wiper Blade Replacement: While you're at it, this is a good time to replace your wiper blades as well. They likely need replacing, especially if your old arms were worn.
If you're uncomfortable performing this repair yourself, take your vehicle to a qualified mechanic. It's a relatively simple job, but it's always better to err on the side of caution if you're unsure.
