What does the term "torque" refer to in vehicle service?

The term "torque" refers specifically to the measure of rotational force applied to fasteners. In the context of vehicle service, torque is critical when tightening bolts, such as those found in engine components, suspension parts, or wheel lug nuts. Proper torque ensures that these fasteners are secured to the correct specifications, which is vital for safety and performance.

When a technician applies torque, they must use a torque wrench to achieve the recommended settings provided by the vehicle manufacturer. This precise measurement helps to avoid over-tightening (which can strip threads or cause damage) or under-tightening (which can lead to components becoming loose and potentially failing during operation).

Understanding torque is essential in vehicle service because it ensures that components are assembled correctly and function safely and effectively within the mechanical systems of a vehicle.
