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 precise torque specifications important for exhaust bolts?
Why are precise torque specifications important for exhaust bolts?
Incorrect torque can lead to premature failure of the exhaust system. Too little torque and bolts may loosen, potentially causing exhaust leaks, noise, and safety hazards. Too much torque can damage the exhaust manifold or cylinder head threads, necessitating expensive repairs.
Q2 What if I don't have the correct torque wrench?
What if I don't have the correct torque wrench?
Using a wrench that isn't calibrated for the specific torque value can result in under- or over-tightening. Consult a professional mechanic if you lack the proper tools or the confidence to use them correctly.
Q3 My exhaust is making a rattling noise. Could it be a loose bolt?
My exhaust is making a rattling noise. Could it be a loose bolt?
A common sign of a loose exhaust bolt is a rattling noise, especially at higher RPMs. Regular checks and torque adjustments are crucial. A loose exhaust can also lead to a reduction in vehicle performance.
Q4 How often should I check the exhaust bolt torque?
How often should I check the exhaust bolt torque?
Inspect exhaust bolt torque during routine maintenance, at least every 10,000 miles, or more frequently if the vehicle is used in harsh conditions (e.g., towing, off-road driving). This is especially important if you hear unusual noises coming from the exhaust system.
