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 correct torque specifications important for body bolts?
Why are correct torque specifications important for body bolts?
Correct torque specifications are crucial to ensure proper clamping force, preventing loosening due to vibrations or stress. Over-tightening can damage the bolt, threads, or surrounding body panels, potentially leading to leaks, squeaks, or structural weaknesses. Under-tightening can cause components to shift or detach, resulting in similar issues and potential safety hazards. For example, a loose fender bolt can cause rattles and potentially detach at higher speeds.
Q2 Where can I find the specific torque specs for my 2020-Present Cadillac CT5?
Where can I find the specific torque specs for my 2020-Present Cadillac CT5?
The most accurate torque specifications can be found in the official Cadillac service manual specific to your CT5's model year. You may also find some specifications in online automotive databases, but always verify with the official source when possible, as torque specifications are very precise.
Q3 What type of tool should I use to tighten body bolts?
What type of tool should I use to tighten body bolts?
A torque wrench is essential for achieving accurate torque. A standard wrench may not give you the precise torque you need. Using a torque wrench helps you avoid under or overtightening bolts. For instance, using a regular wrench on a bumper support bolt may lead to under-torque, making the bumper insecure. Torque wrenches come in various drive sizes (e.g., 1/4", 3/8", 1/2"), make sure you choose one appropriate for your socket and the job you're performing.
Q4 Should I use threadlocker on body bolts?
Should I use threadlocker on body bolts?
The need for threadlocker varies depending on the specific bolt location and Cadillac’s recommendations. Some body bolts, especially those in areas susceptible to vibration, may benefit from threadlocker to prevent loosening. Consult your Cadillac service manual for specific instructions. An example of this would be a bolt attaching a side skirt to the body; this may benefit from thread locker due to increased airflow.
Q5 What should I do if I accidentally over-torque a body bolt?
What should I do if I accidentally over-torque a body bolt?
If you over-torque a body bolt, it is best practice to replace it and check the threads of the surrounding nut or body panel. Over-torquing can stretch or even break a bolt, and the bolt may be compromised and will not hold its original clamping force, even if you back it off. An example would be if you over-torque a door hinge bolt, it may be stripped and compromise the door's position. Always use a new bolt with the appropriate torque spec and verify that the surrounding threads are not damaged.
