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 What are the torque specifications for the electrical connectors on my 2018-present Hyundai Accent?
What are the torque specifications for the electrical connectors on my 2018-present Hyundai Accent?
Unfortunately, precise torque specifications for all electrical connectors on a 2018-present Hyundai Accent are not readily available in a single, consolidated document. These values are often embedded within the vehicle's repair manual, which is often best accessed via Hyundai's website or a professional repair service. Always refer to the specific wiring diagram and associated service manual for the exact connector being worked on. Improper torque can lead to poor electrical connections, causing issues like intermittent lights, malfunctioning components, or even fire hazards.
Q2 Why is precise torque important for electrical connections?
Why is precise torque important for electrical connections?
Proper torque ensures a consistent, reliable connection between electrical components. Too little torque can lead to loose connections, resulting in intermittent issues, while too much torque can damage the connector or threads, leading to corrosion, breakage, or electrical shorts. This can cause a range of issues from flickering lights to complete system failure. For example, a loose battery terminal connection might cause a car to stall or lose power.
Q3 How do I know if an electrical connector needs tightening?
How do I know if an electrical connector needs tightening?
Inspect all electrical connectors regularly for signs of looseness, corrosion, or damage. If you have experienced intermittent issues like a flickering dashboard light, a malfunctioning radio, or a component that sporadically stops working, checking the related electrical connectors is a good first step. Loose or corroded connections are often the culprit.
