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

Why is it important to use the correct torque specifications?

Using the correct torque is critical to ensure proper clamping force. Over-tightening can cause bolts to stretch, shear, or damage the mating surfaces leading to leaks, component failure, or even engine damage. Under-tightening can lead to loosening, vibration, and eventual failure of the connection. Always follow the manufacturer's specified torque for optimal performance and reliability.

Q2

What tools do I need to properly torque bolts on the 2.4L engine?

You will primarily need a calibrated torque wrench that covers the specified ranges, socket set (metric), and extensions. For hard to reach bolts, articulating or crowfoot wrenches may also be necessary. Ensure your torque wrench is in good working order and calibrated regularly for accuracy. Always confirm the size and type of the bolt before applying torque.

Q3

What if I don't have a torque wrench?

While not recommended, using the 'hand tight plus a specific turn' method, or an educated estimate is a temporary fix. However, these are prone to errors and can result in serious issues. Using a torque wrench is the best practice to ensure you are reaching a specified torque value. You can typically borrow or rent one from local auto parts stores.

Q4

Should I use threadlocker on any of these bolts?

Refer to the specific repair manual for the 2015-2017 Chrysler 200 2.4L engine. Generally, threadlocker (e.g., Loctite) is recommended for bolts subject to vibration or heat cycling, such as those on exhaust manifolds or the crankshaft pulley. However, be sure to use the recommended type of threadlocker, as some are only suitable for specific metals and applications. Overuse of threadlocker, especially high-strength varieties on components that require removal, can lead to extra time and effort during maintenance.

Q5

Are there any specific tightening sequences I should follow?

Yes, for components like the cylinder head, intake manifold, and exhaust manifold, a specific tightening sequence is crucial. This ensures even pressure distribution across the mating surfaces, preventing warping and leaks. Always consult the repair manual for the 2.4L engine for the correct tightening pattern. Failure to follow the sequence can lead to significant engine issues.

Environmental Considerations
