Here's a general guide. However, this is not a substitute for a repair manual specific to your 2001 S-10's engine (4.3L V6 or 2.2L I4 are common). Consult your repair manual for precise diagrams, torque specifications, and routing instructions. Improper routing can damage your engine.
Tools You'll Need:
* New serpentine belt: Get the correct size and type for your engine. A parts store can help you identify the correct one based on your vehicle's VIN or engine code.
* Wrench(es): Sizes will vary depending on the tensioner pulley's bolt. You might need a combination wrench or socket set.
* Socket wrench and ratchet: For the tensioner bolt.
* Pliers or channel-lock pliers: Possibly for loosening or tightening the tensioner (depending on the design).
* Gloves: To protect your hands.
* Jack and jack stands (highly recommended): For easier access to the belt. Never work under a vehicle supported only by a jack.
* Repair Manual (highly recommended): Specific to your year and engine.
General Steps (Adapt to your specific engine and tensioner design):
1. Locate the Serpentine Belt: Identify the serpentine belt. It's the long belt that runs around multiple pulleys.
2. Identify the Belt Tensioner: Find the tensioner pulley. This pulley has a mechanism (usually a bolt or lever) to release tension on the belt. This is crucial for removing and installing the belt.
3. Release Belt Tension: This is the trickiest part. Your tensioner may use:
* A Bolt: You'll need to loosen (but *not* remove completely) the bolt on the tensioner. This will allow you to rotate the tensioner pulley, releasing the tension on the belt.
* A Lever: Some tensioners have a lever that you can use a wrench or pliers to move, releasing the tension.
4. Remove the Belt: Once the tension is released, carefully work the belt off the pulleys. Start with the largest pulley (often the crankshaft pulley).
5. Install the New Belt: Carefully route the new belt onto the pulleys in the *same order* as the old belt. Again, consult your repair manual for the correct routing. A misrouted belt can cause serious engine damage.
6. Tighten the Tensioner: Once the new belt is on all the pulleys, tighten the tensioner bolt or lever back to its original position. Ensure the tensioner is secure.
7. Check Belt Tension: Make sure the belt is properly tensioned by pushing on the longest span of the belt. There should be only slight give. If it's too loose or too tight, you'll need to adjust the tensioner.
8. Reconnect the Battery: After you've double-checked everything, reconnect the negative battery terminal.
9. Start the Engine: Start the engine and listen for any unusual noises. If you hear squealing or other problems, double-check your work, particularly the belt routing and tension.
Important Considerations:
* If you're uncomfortable performing this repair, take your vehicle to a qualified mechanic. Improper installation can damage the engine.
* Take pictures before you begin. This will help you remember the belt routing if you get stuck.
* Use the correct tools. Using the wrong tools can damage parts or lead to injury.
* Dispose of the old belt properly.
This is a general overview. The specific procedure may vary slightly depending on your particular S-10 model and engine. Always consult your repair manual for detailed instructions specific to your vehicle. A mistake can lead to serious engine damage.
