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 drivetrain bolts?
Why are torque specifications important for drivetrain bolts?
Incorrect torque settings can lead to premature failure of bolts, causing damage to components like the engine mounts, transmission, or exhaust system. Too little torque allows bolts to loosen, potentially leading to vibrations, noises, and ultimately, catastrophic failure. Too much torque can strip the bolt threads or damage the surrounding components, resulting in costly repairs. Proper torque ensures optimal performance and longevity of the drivetrain.
Q2 What if I don't have the correct torque wrench?
What if I don't have the correct torque wrench?
Using a torque wrench that doesn't match the required specifications is dangerous. If the wrench is too weak, it won't achieve the necessary clamping force. If it's too strong, it may damage the fastener or component. Consult the manufacturer's service manual for the correct torque wrench and specifications. A general rule is to use a wrench calibrated for the size and type of bolt.
Q3 How do I know which torque spec applies to my specific situation?
How do I know which torque spec applies to my specific situation?
Always consult the specific service manual for your 2006-2011 Hyundai Accent. Torque specifications vary depending on the specific bolt location (e.g., engine mount, transmission mount, exhaust manifold). Different engine/transmission combinations might also have different specs. Using the correct part number is critical for accurate specifications.
Q4 What should I do if a drivetrain bolt breaks?
What should I do if a drivetrain bolt breaks?
Immediately take the vehicle to a qualified mechanic. A broken bolt, especially in the drivetrain, can cause significant damage and safety hazards. Do not attempt to repair this yourself. Improper repair could result in further damage, injury, or vehicle malfunction.
