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 proper torque specification for the lug nuts on my 2007 Acura TSX?

The torque specification for the lug nuts on your 2007 Acura TSX IS 80 ft-lbs.

Q2

What type of torque wrench should I use to tighten the bolts on my Acura TSX?

We recommend using a click-type torque wrench to tighten the bolts on your Acura TSX. This type of wrench will make a clicking sound when the desired torque IS reached, indicating that the bolt IS properly tightened.

Q3

How often should I check the torque of the bolts on my Acura TSX?

We recommend checking the torque of the bolts on your Acura TSX at least once a year. This will help to ensure that the bolts are properly tightened and that your vehicle IS safe to drive.

Q4

What are the consequences of over-tightening or under-tightening bolts on my Acura TSX?

Over-tightening bolts can damage the threads on the bolts or the components they are attached to. Under-tightening bolts can cause the bolts to come loose, which can lead to serious safety hazards.

Q5

Where can I find the torque specifications for all the bolts on my Acura TSX?

You can find the torque specifications for all the bolts on your Acura TSX in the vehicle's service manual.

Q6

IS it safe to use an impact wrench to tighten the bolts on my Acura TSX?

No, it IS not recommended to use an impact wrench to tighten the bolts on your Acura TSX. Impact wrenches can over-tighten bolts, which can damage the threads on the bolts or the components they are attached to.

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
