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 torque specifications important for electrical connections?
Why are torque specifications important for electrical connections?
Proper torque ensures a secure electrical connection with adequate contact pressure, minimizing resistance and preventing overheating or arcing. Under-torquing can lead to loose connections and intermittent faults, while over-torquing can damage threads, connectors, or components.
Q2 What happens if I overtighten a bolt in the electrical system?
What happens if I overtighten a bolt in the electrical system?
Overtightening can strip threads, crack plastic housings, or distort metal connectors. This can lead to poor connections, short circuits, and component failure. For example, overtightening a battery terminal bolt can damage the post, making it difficult to create a good connection in the future.
Q3 Are torque specifications the same for all bolts in the electrical system?
Are torque specifications the same for all bolts in the electrical system?
No. Torque specifications vary depending on the bolt size, material, and the components being joined. Consult the vehicle's repair manual for specific torque values. For example, smaller bolts securing a sensor will have much lower torque specs than those used for the starter or alternator.
Q4 Where can I find the correct torque specifications for my 2013-2021 Acura ILX?
Where can I find the correct torque specifications for my 2013-2021 Acura ILX?
The most reliable source for torque specifications is the official Acura ILX repair manual for your specific model year. These manuals are often available online or through a dealership. Also, reputable online automotive databases, and third-party repair guides may have torque information, though accuracy should be confirmed.
Q5 Do I need to use a torque wrench when working with electrical components?
Do I need to use a torque wrench when working with electrical components?
Yes, using a calibrated torque wrench is highly recommended when working with electrical connections. It ensures that fasteners are tightened to the manufacturer's specified torque, reducing the risk of damage or connection problems. Trying to tighten 'by feel' is not precise enough, especially with smaller fasteners.
