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 specifications important for exhaust bolts?
Why is using the correct torque specifications important for exhaust bolts?
Using the correct torque specification ensures proper sealing and prevents leaks. Over-tightening can stretch or break bolts, while under-tightening can cause exhaust leaks, leading to noise, reduced engine performance, and potential damage to other components. Correct torque also helps to prevent premature wear and allows for proper expansion and contraction of the exhaust system due to heat.
Q2 What happens if I over-tighten the exhaust bolts?
What happens if I over-tighten the exhaust bolts?
Over-tightening exhaust bolts can lead to several issues. It can stretch or snap the bolts, potentially damaging the threads in the exhaust manifold or other connecting components. This can necessitate drilling out broken bolts and re-tapping threads, which is a time-consuming repair. It can also crush the exhaust gasket, leading to leaks. In some cases, it can cause distortion of the exhaust flanges, making proper sealing difficult.
Q3 Do I need to use new exhaust bolts every time I remove them?
Do I need to use new exhaust bolts every time I remove them?
While it's not always mandatory, it is highly recommended to use new exhaust bolts, especially when they are old or heavily corroded. Old bolts can have stretched threads or are more likely to break. New bolts ensure consistent clamping force. Additionally, using new gaskets is always recommended to prevent leaks. Consider using new locking nuts or washers if originally present to provide a secure connection.
Q4 Should I use any anti-seize compound on the exhaust bolts?
Should I use any anti-seize compound on the exhaust bolts?
Yes, using a high-temperature anti-seize compound on the threads of the exhaust bolts is highly recommended. This prevents the bolts from seizing due to heat and corrosion, making removal easier in the future. It also helps in achieving the correct torque, by lubricating the threads and preventing false readings. Apply the compound sparingly and evenly to the bolt threads before installation.
Q5 What if I don't have a torque wrench?
What if I don't have a torque wrench?
While a torque wrench is the most accurate method, you can cautiously tighten the exhaust bolts using a standard wrench by hand. The aim is to tighten them snug, but not extremely tight. Remember this is a temporary method and you should get a torque wrench as soon as possible. It's better to be slightly under than over-tightened but you may still not get the seal right and cause exhaust leaks which can be dangerous. Always check for leaks after you start your car.
