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 so important?
Why are torque specifications so important?
Torque specifications are critical because they ensure proper clamping force between components. Overtightening can damage threads, bolts, or components, leading to leaks, failures, or broken parts. Undertightening can result in leaks, vibrations, and loosening, potentially causing a catastrophic failure. Using a calibrated torque wrench is essential for accuracy. For example, the cylinder head bolts require precise torque in multiple stages to ensure proper sealing of the head gasket on the 2.0L engine.
Q2 What happens if I don't use a torque wrench?
What happens if I don't use a torque wrench?
Without a torque wrench, you are relying on guesswork, which is highly inaccurate. You might overtighten bolts, potentially stripping threads in the aluminum engine block, requiring costly repairs, such as heli-coiling or, even worse, replacing the block. Or, you might undertighten them, which could cause head gasket failure due to the loss of compression. Proper tightening is particularly important for critical components like the connecting rod bolts.
Q3 Are the torque specifications the same for all 2.0L Caliber engines?
Are the torque specifications the same for all 2.0L Caliber engines?
Yes, the 2.0L engine torque specifications provided generally apply to all 2007-2012 Dodge Caliber models with the 2.0L engine. However, always refer to a specific repair manual for your year model to confirm these values as small updates may have been made year to year. It is always best practice to use the factory service manual whenever available.
Q4 What does 'torque to yield' mean?
What does 'torque to yield' mean?
'Torque to yield' (TTY) bolts are designed to stretch slightly when tightened, creating a very precise clamping force. These bolts are typically used in critical areas like cylinder heads and main bearing caps. They usually have specific tightening sequences and are often single-use items which must be replaced after removal. Trying to reuse a TTY bolt can lead to improper clamping and gasket failures.
Q5 Why do some bolts require 'angle torque' after an initial torque?
Why do some bolts require 'angle torque' after an initial torque?
Angle torque is often used in conjunction with an initial torque spec to achieve the correct stretch and clamping force, especially with 'torque to yield' bolts. It requires a torque wrench and an angle meter or a wrench with an angle gauge. The initial torque seats the bolt, and then rotating the bolt a specific angle stretches the bolt to provide optimal clamping force. The cylinder head bolts, for instance, require both an initial torque, and then a specified angle of rotation.
