Tools You'll Need:
* New serpentine belt: Make sure you have the correct belt size. Your owner's manual or a parts store can confirm this.
* Wrench or socket set: You might need these to loosen or slightly adjust pulley positions for belt installation. This is rarely necessary, but helpful to have handy.
* Screwdriver (possibly): Some tensioners might require a screwdriver to release tension.
* Gloves (recommended): Protect your hands.
* Shop rags or paper towels: To clean up any debris.
Steps:
1. Locate the Tensioner: The serpentine belt tensioner is a pulley with a mechanism to release tension on the belt. This is usually a spring-loaded pulley with a bolt or lever. Identify this first. Your repair manual will show exactly where it is.
2. Release Belt Tension: This is the most critical part. You need to loosen the tensioner enough to allow you to slip the belt off the pulleys. There are usually a few ways to do this:
* Lever-type tensioner: A lever might be visible, often requiring you to push or pull it in a specific direction while slipping the belt off.
* Bolt-type tensioner: This will involve using a wrench to turn a bolt or nut to reduce tension. *Caution: Be careful not to over-tighten after installation.*
3. Remove the Old Belt: Once tension is released, carefully work the belt off each pulley, starting with the loosest pulley(s) and working your way around.
4. Inspect Pulleys and Components: Before installing the new belt, check all pulleys and the tensioner for cracks, damage, or excessive wear. Replace any faulty components.
5. Install the New Belt: Starting at the loosest pulley(s) (often the crankshaft pulley), carefully route the new belt around each pulley according to its specific path. Your owner's manual or a diagram from a repair manual will show the correct routing. This is very important to get right.
6. Re-tighten the Tensioner: Once the belt is on all the pulleys, carefully re-tighten the tensioner back to its correct position. Refer to your repair manual for the correct tension. You should feel some resistance when you press on the longest run of the belt. The manual may specify a deflection measurement or provide a tightening torque specification.
7. Check Belt Alignment: Make sure the belt is properly seated on all the pulleys and is running correctly. Spin the pulleys by hand to ensure smooth movement.
8. Start the Engine: Start the engine and check for any squealing or slippage from the belt. If you hear anything unusual, turn the engine off immediately and re-check the belt routing and tension.
Important Considerations:
* Safety First: Always disconnect the negative battery terminal before starting any work on your vehicle.
* Repair Manual: A repair manual specific to your vehicle is strongly recommended for detailed instructions and diagrams. These manuals often include torque specifications and other crucial details.
* Professional Assistance: If you are unsure about any part of this process, consult a qualified mechanic. Incorrect belt installation can lead to serious engine damage.
This is a general guide. The specific procedure might vary slightly depending on the exact configuration of your 1994 Ford Tempo. Always prioritize safety and consult your owner's manual or a repair manual for accurate instructions.
