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 What is the recommended torque specification for the HVAC bolts on my 2010-2018 Volvo V60?
What is the recommended torque specification for the HVAC bolts on my 2010-2018 Volvo V60?
The recommended torque specification for the HVAC bolts on your 2010-2018 Volvo V60 is 10-15 Nm (7-11 ft-lbs) for the compressor mounting bolts, and 5-7 Nm (3.7-5.2 ft-lbs) for the condenser coil mounting bolts. It's essential to consult your owner's manual or a repair manual for specific torque values, as over-torquing can damage the components.
Q2 How often should I inspect and maintain the HVAC system on my Volvo V60?
How often should I inspect and maintain the HVAC system on my Volvo V60?
It's recommended to inspect the HVAC system every 12,000 to 15,000 miles, or as specified in your owner's manual. Check for signs of wear, corrosion, or damage on the bolts, hoses, and other components. Regular maintenance can help prevent costly repairs and ensure optimal system performance.
Q3 Can I use a torque wrench with a socket extension to tighten the HVAC bolts?
