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 torque specifications important for body bolts?
Why are torque specifications important for body bolts?
Correct torque is crucial to ensure proper clamping force, preventing bolts from loosening due to vibration or stress. Under-torquing can lead to parts detaching, and over-torquing can damage threads or deform body panels. For example, if a bumper bracket bolt is under-torqued, the bumper might become loose and misaligned, or fall off. Over-torquing body bolts, such as a door hinge bolt, can damage the hinge or door panel.
Q2 What happens if I don't use a torque wrench?
What happens if I don't use a torque wrench?
Using a wrench without measuring torque is highly discouraged. You risk either under or over-tightening the bolts, potentially leading to component failure, damage, or unsafe conditions. Guessing tightness 'by feel' is not accurate. For example, a body side moulding held on with bolts that are not torqued correctly might come loose or create a gap over time. A torque wrench ensures accurate and repeatable results.
Q3 Are all body bolts the same torque specification?
Are all body bolts the same torque specification?
No. Different size bolts, materials and locations on the vehicle will have different torque specifications. For instance, smaller bolts securing a headlight assembly will require less torque compared to larger bolts holding a bumper or door hinges. Always consult the specific torque specifications for the specific bolt in the service manual or trusted source.
Q4 How often should I check the torque on body bolts?
How often should I check the torque on body bolts?
Generally, body bolts do not require frequent re-torquing. However, it is advisable to check them after any repair or replacement involving the body panels, or after an impact. Additionally, some consider a torque check on specific bolts with high load and vibration every 2-3 years or 30,000 miles for peace of mind. For example, if you have had body work performed or replaced a fender, double check those fasteners after a few drives.
Q5 What type of lubricant, if any, should I use on body bolts?
What type of lubricant, if any, should I use on body bolts?
Generally, body bolts do not require lubricant unless otherwise specified by the manufacturer. Clean, dry threads provide the most reliable and predictable clamping force. Unless specifically stated in the service manual, avoid using any anti-seize compound, thread locker or oil as this can affect the torque applied and reduce the accuracy of the torque specification. If you are reusing rusty bolts, cleaning them with a wire brush and wire wheel may be beneficial.

Service Procedures
Body Panel Bolt Torque Procedure
This procedure outlines how to correctly torque body panel bolts on a 2013-2019 Buick Encore. Always refer to the specific torque value listed in the service manual for the exact fastener being worked on. Improper torque can lead to structural issues, leaks, or damage.
- 1. Identify the specific bolt to be torqued and reference the correct torque specification for that location in the vehicle's service manual. Examples include: door hinge bolts, fender mounting bolts, bumper mounting bolts, etc.
- 2. Select the appropriate socket and any extensions or universal joints that are needed for access.
- 3. Ensure the bolt is properly threaded into the nut or receiving part. Begin tightening the bolt by hand first to avoid cross-threading.
- 4. Attach the socket to the torque wrench. Set the torque wrench to the specified torque value for the bolt.
- 5. Tighten the bolt smoothly with the torque wrench until the wrench clicks or signals that the desired torque has been achieved. Do not continue to pull once the click is heard/felt.
- 6. If a torque pattern is specified (such as for a multi-bolt component), follow the pattern exactly. Typically, a criss-cross pattern is used to ensure even pressure distribution.
- 7. Recheck the torque on each bolt once the tightening process is complete.
Bumper Fascia Bolt Torque Procedure
This procedure outlines how to correctly torque bumper fascia bolts on a 2013-2019 Buick Encore. Always refer to the specific torque value listed in the service manual for the exact fastener being worked on. Improper torque can lead to structural issues or damage.
- 1. Identify the specific bumper fascia mounting bolts to be torqued. Reference the service manual for the exact bolt locations and their torque specifications.
- 2. Select the appropriate socket, extensions, and any universal joints needed to access the bolts.
- 3. Ensure the bumper is aligned properly before torquing the mounting bolts.
- 4. Start by threading all the bolts by hand to ensure proper alignment and avoid cross-threading.
- 5. Using a torque wrench, tighten each bolt to the specified torque in the service manual.
- 6. When multiple bolts are present, tighten them in a cross pattern to distribute force evenly.
- 7. Recheck the torque on each bolt after the initial torquing process is completed.
Technical Service Bulletins
Potential for Loose Body Bolts
2017-03-15Some 2013-2017 Buick Encore models may experience loosened body bolts due to vibration or improper initial torque during assembly. This can lead to squeaks, rattles, and potential panel misalignment.
Resolution: Inspect all accessible body panel mounting bolts and ensure they are tightened to the specifications outlined in the service manual. Use a calibrated torque wrench to achieve the proper torque value. Pay special attention to front fender bolts, bumper mounting bolts, and door hinge bolts. Apply threadlocker to prevent future loosening if necessary
Corrosion of Fender Mounting Bolts
2018-11-20Some vehicles in certain regions have reported corrosion issues affecting the fender mounting bolts. If corrosion is present, torque values may be compromised and proper seating of the bolts may be affected.
Resolution: Inspect the fender mounting bolts for corrosion. Replace any corroded bolts and ensure the new bolts are properly torqued. Consider applying anti-seize compound to new bolts during installation to protect against future corrosion. Always refer to the factory service manual for the correct torque specifications.
