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.

Frequently Asked Questions
Find answers to common questions about torque specifications
Q1 Why are correct torque specifications important for body bolts?
Why are correct torque specifications important for body bolts?
Correct torque ensures proper clamping force. Overtightening can damage the bolt, surrounding panel, or threads. Undertightening can lead to loose panels, rattles, and potential failure. This is particularly crucial for safety components like bumper reinforcements.
Q2 What happens if I overtighten a body bolt?
What happens if I overtighten a body bolt?
Overtightening can stretch or break the bolt, strip the threads in the body panel or nut, and potentially cause damage to adjacent panels. This could necessitate repair work or replacement of parts. In severe cases, it can lead to structural weaknesses.
Q3 Can I reuse body bolts?
Can I reuse body bolts?
Generally, most body bolts can be reused if they are not damaged (stretched, rusted, or with deformed threads). However, if a bolt has previously been overtightened, it should be replaced. Always inspect bolts before reuse. If unsure, it's best practice to replace.
Q4 What type of lubricant should I use on body bolts?
What type of lubricant should I use on body bolts?
Unless otherwise specified, most body bolts are designed to be installed dry. Some bolts may benefit from a small amount of anti-seize compound if they are located in an area prone to corrosion (e.g., near wheel wells or exhaust). Do not use oil on bolts unless explicitly stated in the service manual. Using the wrong lubricant can impact the torque value.
Q5 Where can I find the specific torque specifications for a particular body bolt if it's not included in this guide?
Where can I find the specific torque specifications for a particular body bolt if it's not included in this guide?
Refer to the official Acura TL service manual for your specific model year (2009-2014). These manuals provide detailed torque specifications, installation instructions, and component diagrams. You can also find information on reputable automotive websites or databases, but always verify the source is reliable.

Technical Service Bulletins
Potential for Loose Bumper Cover Fasteners
2012-05-10Some 2009-2012 Acura TL vehicles may exhibit loose bumper cover fasteners over time due to thermal expansion and contraction. This bulletin addresses proper torque procedures.
Resolution: Inspect all bumper cover fasteners. Ensure they are tightened to the specified torque values (Typically between 10-12 Nm or 7-9 ft-lbs for plastic fasteners and 20-25 Nm or 15-18 ft-lbs for metal fasteners depending on location and bolt type). Use threadlocker where applicable, especially in high vibration areas.
Rattling Door Panels
2013-10-22Reports of interior door panels rattling or creaking in the 2010-2014 TL models. This issue can often be resolved by checking and tightening all fasteners in the door panel assembly.
Resolution: Remove the door panel and inspect the fasteners. Tighten all screws and bolts to the correct torque (Typically 8-10 Nm or 6-7 ft-lbs for interior screws and 10-12 Nm or 7-9 ft-lbs for bolts securing the door panel) and ensure that all clips are properly seated. Add foam padding if necessary.
