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 using the correct torque specification important for body bolts?
Why is using the correct torque specification important for body bolts?
Using the correct torque specification is crucial to ensure proper clamping force and prevent damage to body panels and the chassis. Over-tightening can strip threads, crack panels, or distort the body structure. Under-tightening can lead to loosening over time, causing rattles, misalignment, and potential safety issues. For example, improperly torqued fender bolts could cause vibrations and premature paint wear.
Q2 What type of lubricant, if any, should I use on body bolts before tightening?
What type of lubricant, if any, should I use on body bolts before tightening?
Generally, body bolts should be installed dry unless specified otherwise by Cadillac. Using lubricant can alter the friction between the bolt and the threads, potentially leading to over-tightening and inaccurate torque readings. If the bolt is corroded or damaged, replacement is preferred over lubrication.
Q3 How often should I check the torque of body bolts?
How often should I check the torque of body bolts?
It is recommended to check the torque of critical body bolts, such as those securing bumpers, fenders, and doors, after any repair or significant impact. Routine checks, perhaps every 12 months or 12,000 miles, can also be beneficial, especially on vehicles that frequently experience rough road conditions. For example, after a minor accident repair involving the front bumper, these bolts should be checked promptly. A general visual inspection should occur more frequently - perhaps when you wash the vehicle.
Q4 Can I reuse body bolts or should they be replaced each time?
Can I reuse body bolts or should they be replaced each time?
It is generally acceptable to reuse body bolts unless they show signs of damage, corrosion, or stretching. However, for critical applications or if a bolt has been removed multiple times, it is advisable to replace it. Always inspect the threads of the bolt and the receiving nuts or weld-nuts carefully before reuse. Bolts exposed to road salt or significant stress should be replaced to ensure proper structural integrity.
