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 specification?
Why is it important to use the correct torque specification?
Using the correct torque specification ensures that body bolts are tightened properly. Over-tightening can damage the bolt, threads, or surrounding panels, leading to component failure or stress cracks. Under-tightening can cause bolts to loosen over time, resulting in rattles, misalignment, or even the separation of panels. For instance, an incorrectly torqued fender bolt could result in a loose fender that vibrates while driving.
Q2 What happens if I don't have a torque wrench?
What happens if I don't have a torque wrench?
While it's possible to tighten bolts without a torque wrench, it is HIGHLY discouraged for body components. Relying on feel can easily lead to over or under-tightening. The risk of damage or future issues significantly increases. Using a torque wrench is crucial for accurate and safe repairs. You can rent one from most auto parts stores if you don’t own one.
Q3 Do these torque specs apply to all Acura MDX models from 2022 onwards?
Do these torque specs apply to all Acura MDX models from 2022 onwards?
These torque specifications are generally applicable to the 2022-present Acura MDX models. However, always consult the specific service manual or repair guide for your particular trim and model year. Minor variations can sometimes exist depending on the specific production batch or component design changes. Checking the manufacturer's document is always the safest course of action. For instance, the mounting of an Advanced Package trim side skirt could differ slightly in torque spec from the base model.
Q4 Should I use thread locker on body bolts?
Should I use thread locker on body bolts?
Generally, thread locker is not required on most body bolts unless specifically indicated in the service manual. Some areas, such as those subjected to high vibration, might recommend a thread locker. However, the use of thread locker without proper guidance can make removal more difficult and may even damage the threads. If you are unsure, consult the specific service manual for guidance on whether your application requires a thread locker.
