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 is the recommended torque specification for the exhaust bolts on a 2006-2012 Mitsubishi Outlander?
What is the recommended torque specification for the exhaust bolts on a 2006-2012 Mitsubishi Outlander?
The recommended torque specification for the exhaust bolts on a 2006-2012 Mitsubishi Outlander is 30-40 ft-lbs (40-54 Nm) for the exhaust manifold bolts and 20-30 ft-lbs (27-40 Nm) for the exhaust pipe flange bolts. It's essential to consult the repair manual or the manufacturer's instructions for specific torque values, as they may vary depending on the engine type and exhaust system configuration.
Q2 Why is it important to follow the recommended torque specification for exhaust bolts?
Why is it important to follow the recommended torque specification for exhaust bolts?
Following the recommended torque specification for exhaust bolts is crucial to ensure the exhaust system is properly sealed and to prevent damage to the engine, exhaust components, and surrounding structures. Over-torquing can lead to stripped threads, damaged bolts, or cracked exhaust components, while under-torquing can result in leaks, reduced performance, and increased emissions.
Q3 How often should I inspect and maintain the exhaust bolts on my 2006-2012 Mitsubishi Outlander?
How often should I inspect and maintain the exhaust bolts on my 2006-2012 Mitsubishi Outlander?
It's recommended to inspect the exhaust bolts every 12,000 to 15,000 miles (19,312 to 24,140 km) or during routine maintenance, such as oil changes or tire rotations. Look for signs of wear, corrosion, or damage, and tighten or replace the bolts as needed to maintain the exhaust system's integrity and performance.
