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

Why is it important to use the correct torque specifications for body bolts?

Using the correct torque ensures proper clamping force, preventing bolts from loosening over time due to vibrations or stress. Under-torqued bolts can lead to panel misalignment, rattles, and potential separation, while over-torquing can damage the bolt threads, body panels, or both. It is critical for maintaining the structural integrity and safety of your Acura RLX.

Q2

What happens if I don't have a torque wrench?

While it's possible to use a standard wrench, it's highly discouraged for body bolts. Torque wrenches provide a precise measure of the force applied, whereas relying on feel can lead to inconsistencies and potentially damaged threads or improper clamping. Renting or borrowing a torque wrench is strongly recommended.

Q3

Do I need to replace body bolts every time I remove them?

Generally, body bolts can be reused if they appear to be in good condition. However, it is always a good practice to inspect the bolts for any signs of damage, corrosion, or stretching prior to re-installation. If any signs of damage are present, the bolt should be replaced. For critical components, the service manual may specify single-use bolts. Refer to your Acura's specific service manual to verify any specific guidelines.

Q4

Are all body bolts on my 2014-2020 Acura RLX torqued to the same specification?

No, torque specifications for body bolts vary depending on the bolt's size, location, and the materials being joined. Always refer to the specific torque specification for each bolt as outlined in the Acura RLX service manual or a reliable source like a parts database or repair guide. Examples might include different torque for the bumper bolts vs. the door hinge bolts.

Q5

What should I do if a bolt feels like it's stripping while tightening?

Stop immediately. Over-tightening can cause bolts to strip or break. Remove the bolt carefully and inspect both the bolt and the threaded hole for damage. If the threads are stripped, you may need to repair the threads using a thread repair kit or replace the damaged component. It is never wise to continue attempting to torque a damaged bolt.

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
