Engine compartment insulation keeps heat and noise in the engine bay from reaching a vehicle's interior. Thermal insulation protects drivers, operators, and passengers from high temperatures that can also damage on-board electronics such as GPS tracking systems. An engine mount consists of two attached metal parts with rubber in between. One side of the mount is bolted to the engine while the other is attached to the frame. The rubber in the center absorbs vibrations while allowing a small amount of movement.
