Driver Side Front Engine Compartment Outer Rail – GM (23216151)

Driver Side Front Engine Compartment Outer Rail routes fluid through the engine bay or underbody. The crimp or flare is the usual failure point, and it fails from vibration rather than from pressure.

Replace the Compartment Outer Rail when a leak appears at a flare or when the line has been bent close to a heat source. Routing must follow the original path or it will chafe.

This Compartment Outer Rail is listed under part number 23216151, filed under Complete Engines. If the original number is unreadable, send us the VIN and we will confirm the reference before dispatch.

The stock here is genuine GM, and this Compartment Outer Rail keeps the original engineering number, which matters once a number has been superseded more than once.

This listing is specifically for the driver (left-hand) side; the opposite side is a separate part number.
