Tools You'll Need:
* New serpentine belt: Make sure you get the correct size and type for your 1998 Pontiac Transport. The part number is usually found in your owner's manual or online auto parts websites (using your vehicle's VIN is recommended).
* Socket wrench set: You'll likely need various sizes, including likely a 13mm and possibly others depending on your specific tensioner.
* Ratchet: To use with your sockets.
* Wrench (possibly): Some tensioners use a wrench, others a socket. Check your car's specifics.
* Jack and jack stands (highly recommended): This makes accessing the belt much easier and safer. Never work under a car supported only by a jack.
* Wheel chocks: For added safety.
* Gloves: To protect your hands.
* Shop rags or paper towels: To clean up any spilled fluids.
* Pry bar (optional but helpful): May be needed to help maneuver the belt onto the pulleys.
Steps:
1. Safety First: Park your vehicle on a level surface, engage the parking brake, and chock the wheels. Raise the front of the car using a jack and securely support it with jack stands.
2. Locate the Serpentine Belt: The serpentine belt is the long, ribbed belt that drives various components like the alternator, power steering pump, and air conditioning compressor.
3. Identify the Belt Tensioner: This is a pulley with a mechanism to release tension on the belt. It's usually located near the belt itself.
4. Release Belt Tension: This is the crucial step. The method varies depending on your specific vehicle. Some tensioners are spring-loaded and require you to use a socket or wrench on a bolt to rotate the tensioner, releasing tension on the belt. Others may have a lever or other mechanism. Consult your repair manual to identify the correct method for your Pontiac Transport's tensioner. You'll need to carefully maneuver the socket or wrench to put tension on the right part of the mechanism to release belt tension.
5. Remove the Old Belt: Once the tension is released, the belt should be loose enough to slip off the pulleys. Work your way around the pulleys, guiding the belt off each one.
6. Install the New Belt: Carefully route the new belt onto the pulleys in the same order as the old belt. It can be helpful to refer to a diagram or a photo of the old belt routing if you are unsure.
7. Re-engage the Tensioner: Once the new belt is on all the pulleys, carefully re-engage the belt tensioner mechanism. The tension should be released when you remove the tensioning tool, which will tighten the belt.
8. Check Belt Tension: Make sure the belt is properly tensioned. You should be able to press down on the longest span of the belt with your thumb and it should only deflect slightly. The repair manual may offer a more precise method for checking tension.
9. Lower the Vehicle: Carefully lower the vehicle using the jack.
10. Start the Engine: Start the engine and listen for any unusual noises. Check all the components driven by the belt (alternator, power steering pump, A/C compressor) to ensure they are functioning correctly.
Important Notes:
* Consult your repair manual: This guide is a general overview. Always consult your vehicle's repair manual for specific instructions and torque specifications. The manual will show you exactly how to release the tension on the belt tensioner for your model.
* Safety: Working under a car can be dangerous. Always use jack stands and follow proper safety procedures.
* Belt Routing: Pay close attention to how the belt routes over the pulleys. Incorrect routing can cause premature belt failure or damage to other components. If unsure, take a picture of the old belt before removing it.
If you are uncomfortable performing this repair yourself, it's always best to take your vehicle to a qualified mechanic. This task requires some mechanical aptitude and the wrong approach could lead to damage to your vehicle.
