Torque wrenches may seem like a luxury you don’t need, but they are actually used for a very specific, very important reason. They are versatile tools that can be used for multiple applications. The most common and prevalent use of a torque wrench is for changing rims.
Can you tighten lug nuts without a torque wrench?
There are a couple of tools you can use to get lug nuts just as tight as a torque wrench. With a crossbar tire iron, choose the right size socket and tighten by hand if you have the arm strength. If not, you need to stand on the right side of the tire iron to turn and tighten the lug nut clockwise.
Is a torque wrench necessary for spark plugs?

How tight should you tighten lug nuts?

|14 x 1.25 mm||85 - 90||9|
|7/16 in.||70 - 80||9|
|1/2 in.||75 - 85||8|

Most torque wrenches are reversible. Assuming you have the type that clicks on reaching the set torque, look for a dial on the back of the head to set the direction.
Do you need torque wrench for oil change?
If you are new to changing your oil though, use a torque wrench and the proper factory torque specs. It's easy to over-tighten a bolt and strip the threads if you don't have practice. You might also need ramps or a floor jack, jack stands, and wheel chocks if you have to go under the vehicle.

What happens if you dont torque spark plugs?
A spark plug that is under-torqued will not be fully seated in the cylinder head and heat dissipation will be slowed. As a result, the firing end of the spark plug can overheat and pre-ignition can occur. Serious engine damage can follow. Over torque can cause the metal shell of the plug to stretch.
How tight do you torque spark plugs?
Should battery be disconnected when changing spark plugs?
No. The battery will not cause any problems when changing the plugs. For a car with “Coil on plug” you disconnect the coils before you remove them, so there's no way any high voltage can be generated.
Why do tire shops over tighten lug nuts?
When tires are rotated or when new tires and/or wheels are mounted on a vehicle, tightening the hardware to the right torque is critical. To compensate for any possibility of loose nuts and bolts, technicians often are tempted to over-torque the wheel hardware.
Can you change a tire without a torque wrench?
A torque wrench is not explicitly necessary; the spare jack and tire iron that come in the trunk of every car are sufficient to change a tire in normal cases. If this was the case, car manufacturers would have to start including torque wrenches with the car in the event of a flat tire.
