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 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 ensures a secure electrical connection. Over-tightening can damage threads, terminals, and components, potentially leading to shorts, loose connections, or component failure. Under-tightening can cause high resistance, which generates heat and may result in intermittent electrical problems or even fires. A proper torque compresses the contact surfaces for low resistance and maintains secure mechanical integrity.
Q2 What happens if I over-tighten an electrical bolt?
What happens if I over-tighten an electrical bolt?
Over-tightening can strip threads in the component or the bolt itself, compromising the integrity of the connection. This can lead to the connection loosening over time, or even damaging the component housing (like a fuse box or relay panel). In electrical connections, this can result in increased resistance, heat buildup, and a potential fire hazard. For example, over-tightening a bolt on the starter solenoid could crack the case, leading to failure.
Q3 Are the torque specs for all electrical bolts the same on my 1984-1990 Chrysler Voyager?
Are the torque specs for all electrical bolts the same on my 1984-1990 Chrysler Voyager?
No, torque specifications vary depending on bolt size, material, and the component it is securing. Larger bolts generally require higher torque. Bolts attaching to plastic housings will require lower torque to prevent damage. Always consult a service manual specific to your vehicle for the correct torque specifications for each particular connection. Never assume all bolts require the same torque.
Q4 Where can I find the correct torque specifications for my specific 1984-1990 Chrysler Voyager?
Where can I find the correct torque specifications for my specific 1984-1990 Chrysler Voyager?
The most reliable source for torque specifications is a factory service manual or a reputable online database specific to your vehicle make, model and year. Generic repair guides may not always have exact specifications, so cross-referencing the info from multiple reliable sources is a best practice.
Q5 Can I reuse electrical bolts after removal?
Can I reuse electrical bolts after removal?
It is generally recommended to replace fasteners that appear damaged or that had thread locker applied during original assembly. Inspect for stripped threads, corrosion, or signs of stretching. If in good condition, and no thread locker is needed, then reusing electrical bolts is acceptable in most cases. Always apply appropriate thread lubricant or compound as required by manufacturer guidelines, and tighten to specified torque.
