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 and reliable electrical connection. Under-tightening can lead to loose connections, increased resistance, overheating, and potential arcing. Over-tightening can damage terminals, wires, and components, potentially leading to failure. Consistent torque application prevents future issues and maintains proper electrical conductivity.
Q2 Can I use a general torque specification if I don't know the exact value?
Can I use a general torque specification if I don't know the exact value?
No, using a general torque specification is not recommended for critical electrical connections. Each component has a specified torque value designed to provide optimal contact without damage. Using incorrect torque can cause electrical faults or component failure. Always refer to the service manual for the correct value.
Q3 What happens if I overtighten a bolt on an electrical component?
What happens if I overtighten a bolt on an electrical component?
Overtightening can deform terminals, crush connectors, or strip threads, leading to unreliable contact and possible component damage. For instance, overtightening a ground terminal on the chassis could damage the lug or the chassis paint preventing the proper ground. It can also create stress on the component leading to premature failure.
Q4 Where can I find the correct torque specifications for my 1994-2001 Acura Integra?
Where can I find the correct torque specifications for my 1994-2001 Acura Integra?
The primary source for correct torque specifications is the official Acura Integra service manual for your specific year. Online forums and databases can provide helpful guidance, but you should always confirm with the official manual to ensure the information is accurate. These manuals usually contain detailed torque charts for various electrical connectors and bolts. For example, the alternator mounting bolts will have different torque spec than the battery terminal clamp bolts.
