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?
Proper torque ensures bolts are tight enough to securely hold body panels and structural components without being so tight that they damage threads or deform the components. Incorrect torque can lead to loose panels, vibrations, leaks, or even structural failure in an accident.
Q2 What happens if I overtighten a body bolt?
What happens if I overtighten a body bolt?
Overtightening can stretch or break the bolt, strip the threads in the body panel or frame, or crush the component being fastened. This can require costly repairs such as replacing the entire component or having threads re-tapped.
Q3 What happens if I under-tighten a body bolt?
What happens if I under-tighten a body bolt?
Under-tightening can result in loose panels or components, leading to rattling, vibrations, increased wear, and potential misalignment. This could cause accelerated wear in moving parts, and if a structural component, cause severe accident damage to be worse than expected.
Q4 Do I need to replace body bolts after removing them?
Do I need to replace body bolts after removing them?
Generally, body bolts can be reused if they are in good condition, with no damage or stretching. However, it is best practice to replace self-locking nuts or bolts designed for single use. Always inspect bolts and replace them if there is any sign of wear or damage, especially if the bolt has any evidence of necking or a stretched head. When in doubt, replace it.
Q5 Should I use thread locker on body bolts?
Should I use thread locker on body bolts?
Thread locker is generally not needed on most body bolts. However, if the service manual or repair instructions for a specific component recommend it, or the bolt is known to be in a high-vibration area, a low-strength thread locker, like a blue thread locker, can be used.
Q6 Where can I find the specific torque specs for my XT5 body bolts if they're not listed in this document?
Where can I find the specific torque specs for my XT5 body bolts if they're not listed in this document?
Always refer to the official Cadillac service manual or a trusted repair database specific to the 2017-Present Cadillac XT5. These sources provide the most accurate torque specifications for every bolt on the vehicle. This ensures you are not using generic specifications that may not be correct for your specific vehicle.
