Here's a general guide. This is NOT a substitute for a repair manual specific to your 1988 Oldsmobile Delta 88. A Haynes or Chilton manual will give you detailed diagrams and torque specifications crucial for proper repair.
Tools You'll Likely Need:
* New serpentine belt: Make sure you get the correct size and type. Your auto parts store can help you find the right one based on your car's VIN or engine type.
* Socket wrench set (metric): You'll need various sizes to potentially loosen tensioners or pulleys.
* Wrench set (metric): Similar to the socket set, you may need some open-end or box wrenches.
* Ratchet and extensions: For easier access to difficult-to-reach bolts.
* Pliers: Possibly needed to help maneuver the belt.
* Gloves: To protect your hands.
* Jack and jack stands (highly recommended): For better access and safety. Never work under a car supported only by a jack.
* Repair manual specific to your 1988 Oldsmobile Delta 88: This is essential for accurate information and torque specifications.
General Steps (Adapt these to your specific car based on your repair manual):
1. Consult your repair manual: This step is crucial. The location and type of tensioner, routing of the belt, and specific bolt sizes vary between engines and even within model years. The manual will show you exactly how the belt runs and which components need to be loosened.
2. Locate the tensioner: Most serpentine belt systems have a tensioner pulley that needs to be released to remove the old belt. This tensioner is usually a spring-loaded device. Your repair manual will show you its location.
3. Loosen the tensioner: Use the appropriate wrench or socket to loosen the tensioner. This will create slack in the belt, allowing you to slip the old belt off. Be careful: Some tensioners require specialized tools, others may use a bolt, and still others may use a lever-type mechanism. Your repair manual is crucial here.
4. Remove the old belt: Once slack is created, carefully slip the old belt off each pulley.
5. Install the new belt: Route the new belt onto each pulley in the same order as the old belt. Your repair manual will show you the correct routing.
6. Tighten the tensioner: Once the belt is on all the pulleys, slowly tighten the tensioner to put tension on the belt.
7. Check the belt tension: Make sure the belt is snug but not overly tight. There's usually a method to check this described in your repair manual. Often there's a specified deflection amount (how much the belt bends when pressed).
8. Reconnect the battery: Once you're satisfied, reconnect the negative battery terminal.
9. Start the engine and check for any problems: Listen for any squealing or unusual noises that could indicate a problem with the belt or pulleys.
Important Considerations:
* Broken Belt: If the belt broke, inspect the pulleys for damage. A broken belt can sometimes indicate a failing pulley.
* Wear and Tear: Regularly inspect your serpentine belt for cracks, fraying, or glazing. Replace it before it fails.
* Safety First: Always use jack stands when working under a car. Never rely solely on a jack.
Remember, this is a general outline. Always refer to a repair manual specific to your 1988 Oldsmobile Delta 88. This will provide the detailed instructions and diagrams necessary to complete the job safely and correctly. If you're uncomfortable with this repair, taking it to a mechanic is always an option.
