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.

Q4 What IS the proper procedure for torquing the intake manifold bolts on a 1998-2001 Kia Sephia?
Q4
What IS the proper procedure for torquing the intake manifold bolts on a 1998-2001 Kia Sephia?
First, clean the bolt threads and mating surfaces. Apply a light coat of oil to the threads. Install the bolts and tighten them to 15 ft-lbs (20 Nm) in a crisscross pattern. Repeat this step and increase the torque to 22 ft-lbs (30 Nm). Finally, torque the bolts to the final specification of 29 ft-lbs (39 Nm).
Q5 What type of torque wrench should I use for my 1998-2001 Kia Sephia?
Q5
What type of torque wrench should I use for my 1998-2001 Kia Sephia?
We recommend using a click-type torque wrench for the most accurate results. Ensure the torque wrench IS calibrated to Kia specifications.
Q6 What are the consequences of over-tightening bolts on my 1998-2001 Kia Sephia?
Q6
What are the consequences of over-tightening bolts on my 1998-2001 Kia Sephia?
Over-tightening bolts can stretch or break the bolts. This can lead to component failure, leaks, and safety hazards.
Environmental Considerations

Temperature Effects
Includes: High Heat, Cold Weather, Thermal Cycling
Temperature can significantly impact torque values and fastener behavior
Cold Weather
Effects:
- Increased material brittleness
- Higher torque required due to thread contraction
- Reduced thread lubricant effectiveness
Recommendations:
- Allow components to warm to room temperature when possible
- 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
