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 crucial to use a torque wrench when tightening electrical connections?
Why is it crucial to use a torque wrench when tightening electrical connections?
Using a torque wrench ensures that electrical connections are neither too loose (causing resistance, heat, and potential failure) nor too tight (risking damage to components or stripped threads). Proper torque is critical for a reliable and safe electrical system. For example, an improperly torqued battery terminal can cause intermittent starting problems or even a fire.
Q2 What happens if I overtighten electrical bolts?
What happens if I overtighten electrical bolts?
Overtightening can damage components, strip threads, or crush the terminals. This can lead to poor electrical contact, increased resistance, and potential heat build-up. For instance, overtightening a grounding bolt on the engine can damage the grounding terminal and lead to erratic sensor readings.
Q3 What happens if I undertighten electrical bolts?
What happens if I undertighten electrical bolts?
Undertightening can result in loose connections which increases resistance, causing heat generation, intermittent electrical faults, and potential component failure. For example, a loose fuse box connection could cause a sudden loss of power to a critical system like the headlights or power steering.
Q4 Are all electrical bolts on my 2022+ Acura ILX tightened to the same torque?
Are all electrical bolts on my 2022+ Acura ILX tightened to the same torque?
No, different electrical components have different torque specifications based on their size, material, and function. Refer to the service manual for the specific torque value for each connection. For example, a small sensor ground wire will have a lower torque specification than a main power cable connection at the starter.
Q5 Where can I find the correct torque specifications for my 2022+ Acura ILX's electrical system?
Where can I find the correct torque specifications for my 2022+ Acura ILX's electrical system?
The most reliable source is the official Acura service manual for the 2022+ ILX. You may also find some information in reputable third-party repair guides. Avoid using generalized torque values; always consult a source specific to your vehicle.

Technical Service Bulletins
Loose Battery Terminal Issue
2023-05-15Some 2022-2023 Acura ILX models may experience loose battery terminal connections causing intermittent electrical issues. This can cause slow starts and the check engine light to come on.
Resolution: Inspect and torque battery terminal connections to 8-10 Nm (70-90 lb-in). If corrosion is present, clean and apply dielectric grease before re-torquing
Grounding Point Corrosion
2023-08-20Reports indicate that grounding points within the engine bay may corrode on 2022-2024 Acura ILX models, leading to erratic electrical behavior. This is especially prevalent in regions with high humidity or salt usage.
Resolution: Inspect all chassis ground locations. Clean any corrosion using a wire brush, apply dielectric grease and then torque to 10-15 Nm (88-133 lb-in). Check each location with a multimeter for proper continuity to chassis
ECU Connector Pin Fit
2023-11-10A small number of 2023-2024 models may have an issue with the pins in the ECU connectors becoming slightly loose, leading to communication issues. Over-tightening can exacerbate this problem. It may also manifest with a no start or intermittent engine code.
Resolution: Inspect the ECU connectors for any signs of looseness. Ensure proper seating of each connector before tightening the retaining bolts to 4-6 Nm (35-53 lb-in). Ensure that the pins themselves are also seated correctly in the connector.
