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 using the correct torque specification so important for emissions sensors?
Why is using the correct torque specification so important for emissions sensors?
Using the correct torque specification for emissions sensors is crucial because over-tightening can damage the sensor, its threads, or the mounting surface, potentially leading to leaks, inaccurate readings, and even sensor failure. Under-tightening can result in the sensor coming loose, also causing leaks and inaccurate readings. Correct torque ensures a proper seal and accurate data transfer to the vehicle's computer, impacting emissions compliance and engine performance.
Q2 What happens if I overtighten an emissions sensor bolt?
What happens if I overtighten an emissions sensor bolt?
Overtightening an emissions sensor bolt can strip the threads in the sensor housing, the manifold, or both. It can also crack the sensor's delicate housing or internal components. This often results in the need to replace the sensor and potentially repair the threads, which is more costly and time-consuming. Additionally, it can cause the sensor to provide inaccurate readings due to internal damage, impacting emissions and engine performance.
Q3 Can I reuse the old emissions sensor bolts?
Can I reuse the old emissions sensor bolts?
It's generally not recommended to reuse old emissions sensor bolts. These bolts can stretch or fatigue over time and may not provide the same clamping force even when torqued to specification. Using new bolts helps to ensure a proper and reliable connection. This is especially important for maintaining a proper seal and preventing leaks which can impact sensor performance.
Q4 How often should I check the torque of emissions sensor bolts?
How often should I check the torque of emissions sensor bolts?
Unless specified in your vehicle's service manual, it's generally not necessary to routinely check the torque of emissions sensor bolts. However, anytime a sensor is removed or replaced, it is crucial to torque the bolts to the correct specification during reinstallation. Regular visual inspection for any signs of looseness or damage around the sensor and mounting points is recommended during routine maintenance.
Q5 What tools do I need to properly torque emissions sensor bolts?
What tools do I need to properly torque emissions sensor bolts?
You will need a torque wrench that is calibrated to the specific torque range for the emissions sensor bolts on your Chrysler 200 (typically in inch-pounds or Newton-meters). A socket of the correct size for the bolt head is also essential. Always consult the service manual for specific socket sizes, and use an accurate torque wrench for proper and safe installation.
