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 correct torque specifications important for electrical connections?
Why are correct torque specifications important for electrical connections?
Proper torque ensures a secure and reliable electrical connection. Over-tightening can damage terminals, wires, or the component itself, leading to shorts, breaks, or intermittent failures. Under-tightening can cause loose connections, resulting in high resistance, overheating, and potential electrical fires or component damage. Think of it like a bridge – too tight or too loose and it'll fail.
Q2 Where can I find the specific torque specifications for my 2006-2011 Cadillac DTS's electrical components?
Where can I find the specific torque specifications for my 2006-2011 Cadillac DTS's electrical components?
The most reliable source is the official Cadillac service manual for your specific model year. You can often find these online or purchase them from automotive parts retailers. Online databases and repair guides may also provide torque specs, but always cross-reference with the official manual when possible. For example, the starter connection or the alternator connection will have specific torque values that can be found in these documents.
Q3 What tool do I need to properly torque electrical connections?
What tool do I need to properly torque electrical connections?
You will need a torque wrench that is properly calibrated and within the required torque range for the specific bolt or fastener. For smaller electrical connectors, a low-range torque wrench (inch-pounds) is often required. Ensure the wrench's calibration is current for accurate results. For example, the mounting bolts for the ECM usually require inch-pound torque, while larger grounds may need foot-pounds.
Q4 What should I do if I accidentally over-tighten an electrical connection?
What should I do if I accidentally over-tighten an electrical connection?
If you suspect you have over-tightened a connection, immediately loosen the fastener and inspect it, as well as the surrounding component for damage. Replace any damaged parts, including wires, terminals, or the bolt itself. Re-tighten to the correct specification using a properly calibrated torque wrench. For example, if a battery terminal is over-torqued, inspect for fractures, and replace if necessary before proper torquing.
Q5 Should I use anti-seize on electrical fasteners?
Should I use anti-seize on electrical fasteners?
Generally, no. Anti-seize can act as an insulator and interfere with proper electrical connections. Most electrical fasteners are designed to have good contact surface. Unless specifically instructed in the manufacturer's documentation, avoid using anti-seize compounds on electrical connectors or fasteners. For example, sensor connectors should never have anti-seize applied.
