Crucial Installation Note:

In official workshop literature, this is classified as a torque-to-yield (TTY) bolt / stretch bolt. Because it undergoes plastic deformation when torqued to its final specification, it is a single-use item. Once removed, it loses its structural integrity and cannot be safely reused—it must be replaced with a new bolt to ensure the engine mount bracket remains securely clamped.
