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 for electrical connections?
Why is it important to use the correct torque specifications for electrical connections?
Using the correct torque is crucial to ensure a secure electrical connection. Under-tightening can lead to loose connections, causing intermittent power, increased resistance, overheating, and potential arcing or sparking. Over-tightening can damage components, strip threads, or weaken fasteners, also leading to connection issues or component failure.
Q2 Where can I find the specific torque specifications for my 1996-2000 Dodge Caravan's electrical components?
Where can I find the specific torque specifications for my 1996-2000 Dodge Caravan's electrical components?
Refer to the official Dodge service manual for your specific year and model of Caravan. These manuals contain the most accurate torque specifications. If a service manual is not available, reputable online databases (such as ALLDATA) or a qualified mechanic can provide this information.
Q3 What happens if I don't have a torque wrench?
What happens if I don't have a torque wrench?
While using a torque wrench is highly recommended for precise tightening, if one is not available you should proceed with extreme caution. Tighten fasteners just enough to feel snug and secure, ensuring not to over-tighten. A 'feel' for correct torque is developed with experience. It is advised to purchase a torque wrench for electrical work, as it can save you from future issues.
Q4 Do torque specifications vary for different electrical components?
Do torque specifications vary for different electrical components?
Yes, torque specifications vary greatly depending on the component, the material of the fastener, and the location of the connection. For instance, torque settings for a battery terminal will be different than those for a sensor or fuse box connection. Always consult the service manual for specific torque values for each individual connection.
Q5 Should I use anti-seize compound on electrical connections?
Should I use anti-seize compound on electrical connections?
Generally, anti-seize is not recommended for standard electrical connections. It can act as an insulator, impeding electrical conductivity. Clean, dry threads are usually preferred. However, for specific connections prone to corrosion (like some battery terminals), a thin layer of dielectric grease is a better choice to prevent corrosion while maintaining conductivity. Consult the service manual for specific recommendations.
