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 exhaust bolt torque specifications important?
Why are exhaust bolt torque specifications important?
Proper torque on exhaust system bolts is crucial for maintaining structural integrity and preventing leaks. Insufficient torque can lead to loose connections, potentially causing exhaust system failure, noise issues (e.g., rattling), and even dangerous emissions. Conversely, over-torqueing can damage the exhaust manifold or bolts themselves.
Q2 What if I don't have the correct torque wrench?
What if I don't have the correct torque wrench?
Using a torque wrench is essential for accurate tightening. If you don't have one, consult a qualified mechanic. Using a regular wrench can lead to damage and incorrect torque, which could compromise the exhaust system.
Q3 How often should I check exhaust bolt torque?
How often should I check exhaust bolt torque?
Inspect exhaust bolt torque during routine maintenance, particularly after any significant repair or modification to the exhaust system. In high-stress driving environments (e.g., towing), checking the torque more frequently may be advisable. This is especially true after a significant number of miles or if you hear unusual noises.
Q4 What if I notice an exhaust leak?
What if I notice an exhaust leak?
A noticeable exhaust leak warrants immediate attention. While you might be tempted to tighten bolts yourself, a leak could indicate a deeper problem (e.g., a damaged gasket). Consult a qualified mechanic to diagnose and repair the leak properly.
