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

What IS the proper torque setting for the cylinder head bolts on a 1985 Chrysler voyager?

The cylinder head bolts must be torqued to 70 ft-lbs in three stages. First, tighten the bolts to 30 ft-lbs, then to 50 ft-lbs, and finally to 70 ft-lbs. Use a torque wrench to ensure accuracy.

Q2

How do I properly torque the lug nuts on my 1989 Chrysler voyager?

Clean the lug nuts and wheel studs, then apply a light coating of anti-seize lubricant. Tighten the lug nuts to 100 ft-lbs using a torque wrench in a star pattern. Recheck the torque after 50 miles.

Q3

What IS the recommended torque setting for the intake manifold bolts on a 1984 Chrysler voyager?

The intake manifold bolts should be torqued to 18 ft-lbs in a crisscross pattern. Use a torque wrench to ensure accuracy and prevent overtightening.

Q4

Can I use a regular wrench to torque bolts on my 1990 Chrysler voyager?

No, always use a torque wrench to tighten bolts on your voyager. A regular wrench can easily overtighten or undertighten bolts, which can lead to damage or failure.

Q5

How often should I check the torque on critical bolts in my 1987 Chrysler voyager?

Inspect and retorque critical bolts, such as those on the suspension, steering, and engine, every 12,000 miles or annually, whichever comes first.

Q6

Where can I find the complete torque specifications for my 1986 Chrysler voyager?

Refer to the Chrysler voyager service manual or consult the Chrysler technical website for the most up-to-date torque specifications for your specific model and year.

Environmental Considerations

  • Consider using winter-grade thread lubricants
  • Check torque values more frequently during winter months

Hot Weather

Effects:
  • Thermal expansion of components
  • Decreased friction in threads
  • Accelerated lubricant breakdown
Recommendations:
  • Check torque when components are at normal operating temperature
  • Use temperature-resistant thread lockers
  • Consider re-torquing after heat cycles

Humidity and Corrosion

Covers: Rust Prevention, Salt Exposure, Moisture Control

Moisture and corrosion can affect fastener integrity and torque values

High Humidity

Effects:
  • Accelerated corrosion formation
  • Reduced friction coefficient
  • Potential thread seizing
Prevention:
  • Use corrosion-resistant fasteners
  • Apply appropriate anti-seize compounds
  • Maintain proper protective coatings

Salt Exposure

Effects:
  • Rapid corrosion development
  • Thread damage
  • Seized fasteners
Prevention:
  • Regular underbody washing
  • Use of sacrificial anodes where appropriate
  • Application of protective coatings

Seasonal Maintenance

Spring

  • Inspect for winter damage
  • Clean and protect exposed fasteners
  • Check torque on critical components

Summer

  • Monitor heat-affected components
  • Check expansion-related loosening
  • Inspect cooling system mounts

Fall

  • Prepare for winter conditions
  • Apply corrosion protection
  • Verify all fasteners are properly torqued

Winter

  • More frequent inspection of critical fasteners
  • Check for salt damage
  • Monitor suspension component torque
