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 torque specification for the lug nuts on a 2021 Hyundai Kona?

108 ft-lbs (146 Nm)

Q2

What tools are required to properly torque the bolts on my 2018 Kona?

A torque wrench, socket set, and appropriate size sockets for the bolts you are tightening.

Q3

How often should I check the torque on the bolts of my 2020 Kona?

Every 5,000 miles or 6 months, whichever comes first.

Q4

Can I use a lubricant or anti-seize when torquing the lug nuts?

Yes, it IS recommended to apply a thin layer of anti-seize to the lug nuts to prevent them from seizing.

Q5

What are the consequences of over-torquing or under-torquing the bolts on my Kona?

Over-torquing can damage the bolts or strip the threads, while under-torquing can cause the bolts to loosen and come loose.

Q6

Where can I find more detailed torque specifications for my specific Kona model?

Refer to the Hyundai service manual for your specific model year and trim level.

Environmental Considerations

Temperature, humidity, and seasonal effects on torque specifications

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

Covers: Rust Prevention, Salt Exposure, Moisture Control

Moisture and corrosion can affect fastener integrity and torque values

High Humidity

Effects:
  • Accelerated corrosion formation
  • Reduced friction coefficient
  • Potential thread seizing
Prevention:
  • Use corrosion-resistant fasteners
  • Apply appropriate anti-seize compounds
  • Maintain proper protective coatings

Salt Exposure

Effects:
  • Rapid corrosion development
  • Thread damage
  • Seized fasteners
Prevention:
  • Regular underbody washing
  • Use of sacrificial anodes where appropriate
  • Application of protective coatings

Seasonal Maintenance

Spring, Summer, Fall, and Winter maintenance schedules

Spring

  • Inspect for winter damage
  • Clean and protect exposed fasteners
  • Check torque on critical components

Summer

  • Monitor heat-affected components
  • Check expansion-related loosening
  • Inspect cooling system mounts

Fall

  • Prepare for winter conditions
  • Apply corrosion protection
  • Verify all fasteners are properly torqued

Winter

  • More frequent inspection of critical fasteners
  • Check for salt damage
  • Monitor suspension component torque

Service Procedures

Wheel Lug Nut Torque Specifications

Technical procedure for tightening wheel lug nuts to the correct torque on a Hyundai kona

  • Clean the lug nut and wheel mating surface to remove dirt and debris.
  • Apply a small amount of anti-seize compound to the lug nut threads.
  • Tighten the lug nuts in a star pattern using a torque wrench to 100 Nm.
  • Double-check the torque on each lug nut to ensure they are all properly tightened.
  • Do not overtighten the lug nuts as this can damage the wheel or lug bolts.
