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 are torque specifications important when working on my 3.6L engine?
Why are torque specifications important when working on my 3.6L engine?
Using the correct torque specifications is crucial to ensure proper clamping force. Under-torquing can lead to leaks and component failure, while over-torquing can damage threads, distort parts, and cause bolts to break. For instance, if you over-torque a cylinder head bolt, you risk warping the head or snapping the bolt, leading to a costly repair. Always use a calibrated torque wrench.
Q2 Do I need to replace bolts when working on my 3.6L engine, specifically head bolts?
Do I need to replace bolts when working on my 3.6L engine, specifically head bolts?
Yes, some bolts, like cylinder head bolts, are often 'torque-to-yield' (TTY) bolts, meaning they stretch when torqued. These MUST be replaced after they've been used. Reusing them can lead to improper clamping and engine damage. Other bolts, especially those subjected to high stress, may also need replacement based on manufacturer guidelines and physical inspection.
Q3 What is a 'torque-to-yield' bolt and why can't I reuse them?
What is a 'torque-to-yield' bolt and why can't I reuse them?
Torque-to-yield (TTY) bolts are designed to stretch and create a specific clamping force. They are not reusable because they deform permanently during tightening. Reusing a TTY bolt will not provide the correct clamping force, leading to gasket leaks, component failure, and potential engine damage. Cylinder head bolts are commonly TTY.
Q4 What if I don't have the exact torque specifications for my 3.6L engine?
What if I don't have the exact torque specifications for my 3.6L engine?
It is extremely dangerous to work without the correct torque specs. Always refer to a reliable service manual specific to your 2015-2017 Chrysler 200 with the 3.6L engine or use a reputable online database. Guessing or relying on general torque guides can lead to severe engine damage, leaks, and unsafe operating conditions. If you cannot find the specifications, do not proceed.
Q5 What tools do I need to accurately torque bolts on my 3.6L engine?
What tools do I need to accurately torque bolts on my 3.6L engine?
You'll need a calibrated torque wrench (digital is recommended for accuracy), sockets of the correct size, and possibly extensions or adapters. For torque-angle applications, an angle gauge or a torque wrench with angle readout is necessary. Inspect your tools before use, and re-calibrate your torque wrench regularly for optimal accuracy. Never use an impact wrench for final tightening; use a hand-operated torque wrench to achieve the correct specs.
Environmental Considerations
