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 is it important to use the correct torque specifications?
Why is it important to use the correct torque specifications?
Using the correct torque specifications ensures that the emissions sensors are properly secured and sealed, preventing leaks and ensuring accurate readings. Over-tightening can damage the sensor or the threads, while under-tightening can lead to leaks or sensor failure. Using a torque wrench is crucial for accurate tightening.
Q2 What should I do if I don't have a torque wrench?
What should I do if I don't have a torque wrench?
While it is highly recommended to use a torque wrench for accurate tightening, if one isn't available, try to tighten the bolts snugly, making sure not to over-tighten. It's better to have them slightly under than over. Then, have the bolt tightness professionally checked as soon as possible. Over torquing can damage the sensor and potentially require more repairs.
Q3 Can these torque specs be used for other Chrysler models?
Can these torque specs be used for other Chrysler models?
While some Chrysler models may share similar sensor types and sizes, it's essential to check the specific torque specifications for each vehicle. This data is specific to the 2007-2010 Chrysler Sebring. Consult your vehicle's repair manual or a reliable database for the correct information for other models.

Technical Service Bulletins
Potential for Stripped Threads on O2 sensor port
2009-05-12Some 2007-2010 Chrysler Sebrings may experience stripped threads on the exhaust manifold or exhaust pipe where the O2 sensors mount due to excessive tightening or overtightening during installation.
Resolution: Use a torque wrench to tighten to the manufacturers recommended torque spec. If the threads are stripped, use a helicoil thread repair kit or replace the affected component.
Sensor Malfunction Due to Loose Bolts
2010-01-28Loose bolts on emissions sensors (such as oxygen sensors) can result in inaccurate readings and trigger the check engine light on certain 2007-2010 Chrysler Sebrings.
Resolution: Inspect and tighten all relevant emissions sensor bolts to the specified torque. Re-check to ensure bolts are tight and sensor is properly installed.
