Which technician is correct about torque specifications for vehicle bolts?

Understanding torque specifications is crucial in vehicle maintenance and repair, as improper torque can lead to mechanical failure and safety issues. Technician A is correct because accurate torque specifications ensure that bolts are tightened to the manufacturer's recommended settings, which can vary based on the application, the type of bolt used, and the environment in which the vehicle operates.

Proper torque helps in providing the right clamping force, preventing leaks in fluid systems, ensuring structural integrity within engine components, and maintaining safety in critical systems such as suspension and braking. Each vehicle and component will have specific torque requirements listed in its service manual, and adhering to these specifications is essential for optimal performance and longevity of the parts.

Using a calibrated torque wrench not only assists in achieving the correct torque but also helps in avoiding issues such as bolt stretch, stripping threads, or even breaking the bolts if too much torque is applied. Understanding and applying the torque specifications accurately reflects a technician's ability to follow manufacturer's guidelines and reinforces the importance of precision in automotive repair.
