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.
Prevention:
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.
Prevention:
Follow the manufacturer's specified torque sequence pattern.
Dirty Threads
Dirt, rust, or old thread locker can affect torque readings and proper fastener tension.
Prevention:
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.
Prevention:
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.
Prevention:
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 for the cylinder head bolts on my 2016-2020 Kia Sorento?
Q1
What IS the recommended torque for the cylinder head bolts on my 2016-2020 Kia Sorento?
The cylinder head bolts should be torqued to 85 ft-lbs (115 Nm) in a three-step sequence. Refer to the Kia technical manual for the specific torque sequence.
Q2 Can I use a standard torque wrench for all bolts on my Sorento?
Q2
Can I use a standard torque wrench for all bolts on my Sorento?
No, you should use a click-type torque wrench that IS calibrated to the correct torque range for the bolts you are tightening. Different bolts require different torque values, so using the wrong torque wrench can result in over- or under-tightening.
Q3 How often should I check the torque on critical bolts?
Q3
How often should I check the torque on critical bolts?
Critical bolts, such as those on the suspension, engine, and transmission, should be inspected and torqued to specifications at regular intervals, such as every 30,000 miles or as recommended in the Kia maintenance schedule.
Q4 What are the consequences of over-tightening or under-tightening bolts?
Q4
What are the consequences of over-tightening or under-tightening bolts?
Over-tightening bolts can stretch or break them, leading to component failure or safety hazards. Under-tightening bolts can result in loose components, vibration, and premature wear.
Q5 Where can I find additional torque specifications for my Sorento?
Q5
Where can I find additional torque specifications for my Sorento?
Refer to the Kia Sorento owner's manual or service manual for comprehensive torque specifications. You can also consult a qualified mechanic or Kia dealership for assistance.
Environmental Considerations

- Consider using winter-grade thread lubricants
- Check torque values more frequently during winter months
Hot Weather
Effects:
- Thermal expansion of components
- Decreased friction in threads
- Accelerated lubricant breakdown
Recommendations:
- Check torque when components are at normal operating temperature
- Use temperature-resistant thread lockers
- Consider re-torquing after heat cycles
Humidity and Corrosion
