Here's why:
* Torque specifications are very precise: They vary significantly depending on the year, model, and engine type. Even minor variations can lead to serious engine damage.
* Safety is paramount: Providing incorrect torque values could result in a poorly tightened head, leading to leaks, premature wear, and even engine failure.
What you should do:
1. Consult your vehicle's owner's manual: The manual will have the most accurate torque specifications for your specific vehicle.
2. Use a reputable repair manual: Search for a repair manual specific to your 2003 Impala 3.4L engine.
3. Contact a qualified mechanic: A mechanic can provide the correct torque specifications and properly tighten the cylinder head bolts.
Remember: Tightening cylinder head bolts is a critical task. Using the correct specifications and proper procedures is essential for engine longevity and safety.
