DIY Trade Knowledge: Understanding Fastener Torque in Automotive Applications
Learning to repair and maintain your car is a worthy endeavor, whether you’re an automotive enthusiast or you just want to ensure that your car is in excellent condition at all times.
While learning how to perform oil changes, tire rotations, and minor engine repairs is important, there’s a small, overlooked detail that you should become acquainted with. It’s called fastener torque.
What Is Torque?
Torque refers to the amount of rotational force that you apply to a bolt, nut, or screw. The amount of torque you should apply depends on your vehicle, the part you are working on, the individual fastener, and other important factors. Each part of your car needs distinct levels of torque to perform well and maintain its structural integrity.
Why Is It So Important?
Can you imagine what would happen if you were to change your brake calipers, but you over-tighten or under-tighten the fasteners? The screws and bolts could come loose, fall out, or they could break off under pressure. That is why fastener torque is so important. It represents a balanced amount of pressure that helps avoid larger consequences down the road.
What Tools Do You Need?
To start your torque adventure, you’ll need to invest in a torque wrench, which measures the amount of force applied to each fastener as you tighten it.
You will also need your vehicle’s owner’s manual. This contains the recommended torque for fasteners for each component and area of your car. When in doubt about a certain part, always refer back to this manual.
What Is the Correct Way To Tighten Fasteners?
The right way to apply fastener torque is with patience.
First, prepare your threads by cleaning them and keeping them free of contaminants and debris. Then, lubricate them, either with lube or with anti-seize, depending on the application. Follow manufacturer instructions on that. This can help prevent seizing and galling.
Then, you can begin to gradually tighten the fastener, applying torque in steps until you reach the recommended level. This way, you evenly distribute the tension.
Follow the tightening sequence that the manufacturer provides. This pattern helps to distribute stress better and can prevent damage and warping. It’s a good idea to mark each fastener that you have tightened correctly so you don’t get confused. You can use a permanent marker or a bit of paint or nail polish.
How Often Should You Check Fastener Torque?
You should recheck the torque periodically, as driving, temperature changes, and impacts can affect the torque values. This is especially true after longer drives, or when you change your engine oil. This will ensure that your vehicle works optimally for years to come.
How Can You Master Torque?
Once you have the right tools, are familiar with your car, and have practiced a little, the process of tightening fasteners will become second nature to you. The more you practice, the easier it will be. Stay consistent.
