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 What are the torque specifications for the exhaust manifold bolts on a 2014-2020 Acura RLX?
What are the torque specifications for the exhaust manifold bolts on a 2014-2020 Acura RLX?
The exhaust manifold bolts on a 2014-2020 Acura RLX typically require a torque specification of 23 lb-ft (31 Nm). Always refer to the specific repair manual for your model year as there can be slight variations. Over-tightening can lead to stripped threads or damaged components.
Q2 What is the torque specification for the exhaust pipe flange bolts connecting to the catalytic converter?
What is the torque specification for the exhaust pipe flange bolts connecting to the catalytic converter?
The flange bolts connecting the exhaust pipes to the catalytic converter usually require a torque specification of 30 lb-ft (41 Nm). Again, consult your repair manual for the exact specification, and use a calibrated torque wrench to ensure accuracy.
Q3 Are the torque specs the same for all bolts along the exhaust system?
Are the torque specs the same for all bolts along the exhaust system?
No, torque specifications vary depending on the bolt size and its location within the exhaust system. For example, the muffler mounting bolts may have a different torque specification than the exhaust manifold bolts. Always consult your repair manual for the specific location you are working on. Using the wrong torque can cause leaks or damage.
Q4 What should I do if I suspect an exhaust leak after reassembling the system?
What should I do if I suspect an exhaust leak after reassembling the system?
If you suspect an exhaust leak, carefully inspect all connections, particularly around gaskets and flanges. You may need to re-torque the bolts, following the correct tightening sequence specified in the service manual. Start the car and listen for hissing noises near the connections. A soapy water spray can help identify leaks if needed; watch for bubbles forming around the leak.
Q5 Do I need to replace the gaskets when reassembling the exhaust system?
Do I need to replace the gaskets when reassembling the exhaust system?
Yes, it's highly recommended to replace all gaskets when reassembling the exhaust system. Old gaskets can become compressed and brittle, which can lead to exhaust leaks. Always use new, genuine Acura replacement gaskets for best results. Reusing old gaskets is a common cause of exhaust leaks and should be avoided.
