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 optimal contact and minimal resistance. Undertightening can cause loose connections, leading to arcing, overheating, and intermittent failures. Overtightening can damage components, stripping threads or causing structural damage. Both can result in electrical malfunctions or even fire hazards.
Q2 Where can I find the correct torque specifications for my 1993-1997 Chrysler Concorde's electrical components?
Where can I find the correct torque specifications for my 1993-1997 Chrysler Concorde's electrical components?
The most reliable source for torque specifications is the factory service manual for your specific year of Concorde. Aftermarket repair manuals often include them, but always double-check against the factory manual if possible. Websites dedicated to vehicle repair can sometimes provide them, but verify their accuracy.
Q3 What tools do I need to properly torque electrical connections?
What tools do I need to properly torque electrical connections?
You'll need a torque wrench that measures within the specified range for your bolts, and the correct size socket. For smaller terminals and grounds, a smaller inch-pound torque wrench will be necessary. An example of where you may need an inch-pound torque wrench is tightening a ground wire to the chassis or a PCM terminal.
Q4 What should I do if a torque specification isn't available?
What should I do if a torque specification isn't available?
If a specific torque is unavailable, use general torque guidelines for bolt sizes and materials. Remember to refer to bolt grade. For example, an M6 bolt may have a very different torque spec for steel vs aluminum components. Using a torque spec for a bolt of a different material can cause damage. When in doubt, it is safer to slightly under-tighten and use thread locker, then re-torque on a second attempt.
Q5 Are there different torque specs for different parts of the electrical system?
Are there different torque specs for different parts of the electrical system?
Yes, absolutely. Different bolt sizes and materials require different torques. A starter motor mounting bolt will have a different spec than a small terminal on a sensor, for example. A larger bolt may require foot-pounds of torque where a smaller terminal may only need inch pounds.
