To find the correct setting, you absolutely must consult a repair manual specific to your car's engine. This manual will show diagrams with the exact locations of the timing marks on the crankshaft and camshaft(s) and explain the procedure for proper timing belt installation. Trying to do this without the correct manual is extremely risky and could severely damage your engine.
Here's why you need the specific manual:
* Engine Variations: Even within the same engine size (e.g., 2.8L V6), there might be minor variations in the timing mark locations between different production years or variations.
* Timing Mark Locations: The precise location of the marks is crucial. Being off by even a few degrees can cause serious engine damage.
* Belt Routing: The timing belt routing is specific to each engine. Incorrect routing will cause the engine to run poorly or not at all.
Where to find a repair manual:
* Online Retailers: Sites like Amazon, eBay, and others sell repair manuals. Search for "1988 Chevy Celebrity [Your Engine Size] repair manual."
* Auto Parts Stores: Many auto parts stores (like AutoZone, Advance Auto Parts) may have access to online repair information or sell printed manuals.
* Online Repair Databases: Some websites offer online access to repair manuals for a subscription fee.
Attempting this without the correct information is strongly discouraged. Improper timing can lead to bent valves, piston damage, and other costly repairs. If you're not comfortable performing this task yourself, take your car to a qualified mechanic.
