What kind of wrench should be used to tighten engine components such as manifolds and cylinder heads?

A torque wrench is specifically designed to apply a precise amount of torque to fasteners, which is crucial when tightening engine components such as manifolds and cylinder heads. These components often require specific torque specifications to ensure that they are secured properly without being over-tightened, which can lead to damage or failure.

Using a torque wrench allows the mechanic to achieve the manufacturer’s recommended torque settings, ensuring the integrity and performance of the engine. This level of control is essential in automotive work, especially for components subject to high stress and temperature changes. In contrast, the other types of wrenches, while potentially useful in various applications, do not provide the necessary precision needed for these critical engine parts.
