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 specifications for body bolts?
Why is it important to use the correct torque specifications for body bolts?
Using the correct torque specifications is crucial for several reasons. Under-tightening can lead to parts loosening over time, causing rattles, misalignment, and potential safety issues. Over-tightening can damage the bolt, threads, or the body panel itself, leading to costly repairs. Proper torque ensures the correct clamping force and joint integrity for the intended design.
Q2 What happens if I overtighten a body bolt?
What happens if I overtighten a body bolt?
Overtightening a body bolt can cause several issues. It can strip the threads in the receiving hole, which then requires a thread repair or replacement of the part. It can also distort the body panel, create stress points, or even break the bolt. Overtightening also makes the bolt harder to remove in the future. For example, overtightening a fender bolt can cause the fender to warp slightly and make proper alignment difficult.
Q3 Do I need to replace body bolts every time I remove them?
Do I need to replace body bolts every time I remove them?
While not always necessary, it is good practice to inspect body bolts for damage, such as stretched threads or rust, before reusing them. If a bolt shows signs of damage, it should be replaced. Self-locking bolts, which use a nylon patch or deformed threads, should always be replaced after removal. Additionally, if a bolt has shown signs of corrosion or has been particularly difficult to remove, its worth replacing to ensure proper clamping force is achieved.
Q4 Can I use threadlocker on body bolts?
Can I use threadlocker on body bolts?
Threadlocker is generally not needed for body bolts unless specifically called for in the service manual. It is used in situations where loosening could cause a more serious issue. When using threadlocker, apply it to the bolt threads and be sure to use the appropriate torque rating. If unsure, consult the service manual.
Q5 How do I access the body bolt torque specifications?
How do I access the body bolt torque specifications?
The most accurate torque specifications will be located in the official Acura service manual for the 2013-2021 ILX. These manuals can often be accessed through a professional mechanic, an Acura dealership, or online subscription services dedicated to service manuals. It is important to use the correct model year as specifications may change slightly.
