Here's how to approach it:
1. Identify your engine: Check your vehicle's paperwork or the engine bay itself to determine if you have a 2.5L 4-cylinder or a 2.8L V6 engine. The routing is different for each.
2. Find a diagram: The best resource is your owner's manual. It *should* have a diagram showing the correct belt routing. If you don't have the manual, try these options:
* Online repair manuals: Sites like Chilton's or Haynes often have repair manuals available for download or purchase. These manuals contain detailed diagrams and instructions.
* Online forums: Search for "1988 Chevrolet Celebrity [2.5L or 2.8L] serpentine belt routing" on forums dedicated to classic Chevy vehicles. You might find someone who has posted a picture or description.
* Auto parts store: Many auto parts stores (like AutoZone, Advance Auto Parts, etc.) can print out a diagram for you if you provide them with your vehicle's year, make, model, and engine size.
3. Inspect the belt and pulleys: Before installing the new belt, inspect all the pulleys for damage or wear. Look for any cracks, grooves, or excessive wobble. Replace any damaged pulleys as needed.
4. Follow the diagram carefully: Once you have the correct diagram, carefully route the belt according to the arrows or numbers shown. It typically starts with the crankshaft pulley and then goes to the water pump, alternator, power steering pump, and other components. The order is crucial.
5. Tensioning: Most serpentine belt systems have a tensioner pulley. This pulley allows you to adjust the belt tension. Refer to your diagram or repair manual for how to properly tension the belt. It usually involves loosening a bolt on the tensioner pulley, allowing you to move it and tighten the belt, and then tightening the bolt once the correct tension is achieved. Do not over-tighten the belt.
6. Check for proper routing and tension: After installing the belt, rotate each pulley by hand to ensure the belt runs smoothly and doesn't slip. Make sure the tension is correct – it should be firm but not excessively tight.
Safety Note: Always disconnect the negative battery cable before working on any automotive repair to prevent accidental electrical shorts. If you're uncomfortable performing this repair yourself, take your vehicle to a qualified mechanic. Incorrect belt routing can cause serious engine damage.
