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?
Correct torque is crucial for electrical connections to ensure proper contact and prevent overheating. Under-torquing can lead to loose connections, causing resistance, heat buildup, and potential electrical failures. Over-torquing can damage components or strip threads, also leading to poor connections.
Q2 Where can I find the correct torque specifications for my 2004-2009 Cadillac SRX electrical system?
Where can I find the correct torque specifications for my 2004-2009 Cadillac SRX electrical system?
The most accurate torque specifications for your vehicle's electrical system can be found in the official Cadillac service manual for your specific model year. It will detail the torque values for various components including sensors, ground connections, and the fuse box. It is highly recommended to use the service manual and not rely solely on generalized specifications.
Q3 What if I can't find the specific torque specification for a small electrical connector?
What if I can't find the specific torque specification for a small electrical connector?
For small, non-critical electrical connectors without specified torque values, it is usually best to use 'snug fit plus a little more.' Avoid using excessive force. Often these smaller components may only require hand tight or very low torque value. If the connector or bolt is integral to the operation of a critical system (such as the ABS system or PCM) proceed with caution and consult the service manual before proceeding.
Q4 What happens if a ground connection is not properly torqued?
What happens if a ground connection is not properly torqued?
Improperly torqued ground connections are a common cause of electrical issues in vehicles. If a ground is loose, it can create high resistance, leading to intermittent electrical problems, dimming lights, inaccurate sensor readings, and reduced performance from electrical components. Correct torque is essential for a reliable connection and proper grounding of the circuit.
