Why a single number is wrong:
The procedure requires tightening the bolts in a specific sequence and in stages. This ensures even clamping force across the entire cylinder head. Skipping steps or using an incorrect torque will likely lead to a warped head gasket, blown head gasket, or other catastrophic engine failure.
Where to find the correct procedure:
To find the correct torque specs and tightening procedure, you must consult a factory service manual for your specific 2002 Chevrolet vehicle with the 5.3L engine. These manuals are available from several sources, including:
* Online retailers: Sites like Amazon or eBay sell both physical and digital copies of factory service manuals. Search for "2002 Chevrolet [Your Vehicle Model] service manual".
* Repair shops: Local repair shops may have access to online service manuals.
* Dealerships: Your local Chevrolet dealership is the most reliable source, but it might be the most expensive.
Using incorrect torque values risks severe engine damage, potentially costing thousands of dollars to repair. Don't attempt this job without the proper information.
