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 critical for body bolts to ensure proper panel alignment, prevent loosening due to vibrations, and maintain the structural integrity of the vehicle. Under-torqued bolts can loosen, causing rattles, misalignment, and potential component damage. Over-torquing can damage the bolt, the threads in the chassis, or the body panel itself.
Q2 What happens if I over-torque a body bolt?
What happens if I over-torque a body bolt?
Over-torquing can stretch the bolt beyond its yield point, weakening it and potentially leading to failure. It can also damage the threads in the vehicle’s frame or the body panel itself, requiring costly repairs such as heli-coiling or even panel replacement. In extreme cases, over-torquing can cause the bolt to shear.
Q3 Can I use a hand wrench instead of a torque wrench?
Can I use a hand wrench instead of a torque wrench?
While a hand wrench can be used to initially tighten the bolt, a torque wrench is essential for the final tightening. A torque wrench allows precise application of the specified torque. Using only a hand wrench can easily result in over- or under-torqued bolts. This is especially critical for body panels where uniform pressure is needed to maintain proper alignment and prevent stress.
Q4 Do I need to replace body bolts after removing them?
Do I need to replace body bolts after removing them?
Generally, most body bolts can be reused unless they show signs of damage like stretching, corrosion, or thread damage. However, certain bolts may be designed to be single use (torque to yield) and will be marked as such in the repair manual. Always inspect bolts carefully before reuse and follow the manufacturer's recommendations. If there is any doubt, replace the bolt.
Q5 How do I find the specific torque specification for a particular body bolt on my 2013-2019 Cadillac ATS?
How do I find the specific torque specification for a particular body bolt on my 2013-2019 Cadillac ATS?
The most reliable source for torque specifications is the official Cadillac service manual for your model year of ATS. These manuals are available through Cadillac dealerships or online subscription services. The specifications are typically organized by component group. Always consult the service manual for the most accurate specifications, as values can vary even within the ATS model range.
