Common Mistakes to Avoid
Common Mistakes to Avoid
Over-tightening
Exceeding the specified torque value can stretch or break fasteners, damage threads, or crack components.
Always use a calibrated torque wrench and follow specifications exactly.
Incorrect Torque Sequence
Tightening bolts in the wrong order can cause uneven pressure distribution and potential leaks or damage.
Follow the manufacturer's specified torque sequence pattern.
Dirty Threads
Dirt, rust, or old thread locker can affect torque readings and proper fastener tension.
Clean and inspect all threads before assembly. Use new thread locker if specified.
Reusing TTY Bolts
Torque-to-yield bolts are designed to stretch and must not be reused.
Always replace TTY bolts with new ones. They are single-use only.
Dry vs. Lubricated
Not accounting for whether torque specs are for dry or lubricated fasteners can lead to incorrect tension.
Check if specs are for dry or lubricated threads. Use specified lubricant when required.

Frequently Asked Questions
Find answers to common questions about torque specifications
Q1 Why are torque specifications important for body bolts?
Why are torque specifications important for body bolts?
Correct torque is crucial to ensure proper clamping force. Over-tightening can damage the bolt, threads, or surrounding body panels, leading to stress fractures or deformation. Under-tightening can cause parts to loosen, leading to rattles, misalignment, or even component failure and safety issues.
Q2 What happens if I over-torque a body bolt?
What happens if I over-torque a body bolt?
Over-torquing can strip the threads in the body panel or the bolt itself, making it difficult or impossible to tighten or loosen in the future. It can also cause the bolt to break, require drilling out, and potential structural damage.
Q3 What if I don't have a torque wrench? Can I just tighten them by feel?
What if I don't have a torque wrench? Can I just tighten them by feel?
While it might seem tempting to tighten by feel, it's highly discouraged, especially for critical components. Using a torque wrench ensures accurate and consistent clamping force, preventing issues from over or under-tightening. If you don't have one, consider borrowing or renting one from an auto parts store or purchase one for proper repair.
Q4 Do body bolts loosen over time? Should I re-torque them?
Do body bolts loosen over time? Should I re-torque them?
Yes, body bolts can loosen over time due to vibration, temperature fluctuations, and settling. While not required for most standard bolts, periodic checks can be beneficial, particularly after major body work or accident repair. Focus on bolts associated with panels that support heavier components (like bumpers). Generally, re-torquing after a few hundred miles of service can be a good practice for these specific types of repairs.
Q5 Are there specific torque values for different locations on the Acura CL's body?
Are there specific torque values for different locations on the Acura CL's body?
Yes, torque specifications vary depending on bolt size, material, and location. For example, bolts securing bumpers might have different torque specs than those securing interior panels or fenders. Always consult the specific manufacturer's service manual or a reliable database that details each specific location. This document only provides typical range. Always defer to the manufacturer specific spec.
