Common Mistakes to Avoid

Over-tightening

Exceeding the specified torque value can stretch or break fasteners, damage threads, or crack components.

Prevention:

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.

Prevention:

Follow the manufacturer's specified torque sequence pattern.

Dirty Threads

Dirt, rust, or old thread locker can affect torque readings and proper fastener tension.

Prevention:

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.

Prevention:

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.

Prevention:

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 is the recommended torque specification for the fuel bolts on my 2006-2009 Pontiac Solstice?

The recommended torque specification for the fuel bolts on your 2006-2009 Pontiac Solstice is 10-12 ft-lbs (14-16 Nm) for the fuel rail bolts and 5-7 ft-lbs (7-10 Nm) for the fuel injector bolts. It's essential to follow the manufacturer's recommended torque specifications to ensure proper sealing and prevent damage to the fuel system components.

Q2

Why is it important to use the correct torque specification for the fuel bolts?

Using the correct torque specification for the fuel bolts is crucial to prevent damage to the fuel system components, such as the fuel rail, fuel injectors, and engine. Over-torquing can lead to stripped threads, damaged components, and costly repairs, while under-torquing can result in leaks, poor engine performance, and decreased fuel efficiency.
