Engine Shield – ACDelco (25749228)

Engine Shield is a formed or cast component that surrounds or supports part of the powertrain. Corrosion and cracking at mounting points are the usual reasons for replacement.

Replace the Engine Shield when you find a crack that weeps under pressure, or when the mounting ears have failed. Welding a casting rarely restores the original alignment.

Reference number for the Engine Shield: 25749228. It is filed under Complete Engines, and it is the number that has to match the part coming off the vehicle.

This is ACDELCO dealer-sourced stock rather than an equivalent, so the number on the Engine Shield traces straight back to the manufacturer.
