Important Information
Safety guidelines and reference information for proper torque application
Safety First
- Always verify torque specifications with your vehicle's factory service manual
- Use properly calibrated torque wrenches
- Replace all torque-to-yield (TTY) bolts - they are single-use only
- When in doubt, consult a professional mechanic

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.
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.
Follow the manufacturer's specified torque sequence pattern.
Dirty Threads
Dirt, rust, or old thread locker can affect torque readings and proper fastener tension.
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.
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.
Check if specs are for dry or lubricated threads. Use specified lubricant when required.

- Use thread locker if specified
Stripped Fasteners
Symptoms:
- Unable to achieve proper torque
- Fastener spins freely
- Visible thread damage
Solutions:
- Use thread repair kit if appropriate
- Install thread insert (HeliCoil)
- Replace component if threaded hole is damaged
- Upgrade to higher grade fastener if recommended
Overtightened Components
Symptoms:
- Cracked or deformed parts
- Broken fasteners
- Compressed gaskets or seals
Solutions:
- Replace damaged components
- Use new fasteners
- Follow proper torque sequence
- Verify correct torque specifications
Diagnostic Steps

Frequently Asked Questions
Find answers to common questions about torque specifications
Q1 What if I don't have a torque wrench? Can I use a regular wrench?
What if I don't have a torque wrench? Can I use a regular wrench?
Using a regular wrench to tighten bolts IS not advisable as it's difficult to achieve the specified torque value and can lead to over or under-tightening. A torque wrench IS required to ensure proper bolt tightness as per Acura specifications.
Q2 IS there a specific tightening sequence for Acura TL bolts?
IS there a specific tightening sequence for Acura TL bolts?
Yes, it's crucial to follow the specified tightening sequence for Acura TL bolts. Randomly tightening bolts can create uneven tension and compromise joint integrity. Refer to the Acura service manual for detailed tightening sequences for each component.
Q3 Can I use aftermarket bolts and still follow the same torque specifications?
Can I use aftermarket bolts and still follow the same torque specifications?
Aftermarket bolts may have different material properties and dimensions compared to genuine Acura bolts. Using aftermarket bolts with specified Acura torque values may result in incorrect tension and compromise joint integrity. Always use genuine Acura bolts and refer to the service manual for specific torque specifications.
Q4 How often should I check and tighten bolts on my Acura TL?
How often should I check and tighten bolts on my Acura TL?
Regularly check and tighten bolts on your Acura TL, especially after major repairs or maintenance. Periodically inspect critical bolts, such as suspension and engine bolts, for any signs of loosening or damage. Follow the recommended torque specifications in the Acura service manual for proper tightening.

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
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
