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 is it important to use the correct torque specification?
Why is it important to use the correct torque specification?
Using the correct torque ensures the bolt is tight enough to hold the components securely but not so tight that it damages the bolt, the threaded hole, or the attached body panels. Over-tightening can lead to stripped threads, sheared bolts, or panel distortion. Under-tightening can cause panels to loosen, vibrate, or even fall off, posing a safety hazard and potentially causing further damage.
Q2 What happens if I over-torque a body panel bolt?
What happens if I over-torque a body panel bolt?
Over-torquing a body panel bolt can lead to several issues. The most common are stripping of the threads, which could require repair or replacement of the affected part. Additionally, you could crack or warp the body panel or component the bolt is holding in place. This could result in a misalignment, poor fit, or even a need to replace expensive panels. Always use a properly calibrated torque wrench to avoid this.
Q3 Can I use threadlocker on body panel bolts?
Can I use threadlocker on body panel bolts?
Generally, threadlocker is not required for most body panel bolts on the 2005-2012 Acura RL, as they are typically not subject to extreme vibration. If you are concerned about a particular bolt loosening, check if the factory service manual specifies the use of threadlocker or provides specific torque specifications. Using it where it's not intended can make future removal difficult or impossible. If required, use a low-strength (e.g., blue) threadlocker.
Q4 Do I need a special torque wrench for body bolts?
Do I need a special torque wrench for body bolts?
A torque wrench is highly recommended for accurate torque application. While a simple wrench might seem acceptable, it's easy to over-tighten body bolts, potentially damaging the vehicle. Investing in a basic click-type or beam-type torque wrench, which accurately measures the applied torque, is a worthwhile investment for any DIY work on your car. Ensure it covers the torque ranges required for the body bolts you will be working on.
