The turbocharger coolant line on certain Buick, Cadillac, Chevrolet and GMC vehicles often leaks because the rubber section of the line doesn't have enough support to keep from splitting. The resulting coolant loss can lead to engine damage. Replacing it with an OEM coolant line could mean the same issue again in the future, a costly waste of time when you're dealing with 12 hours of replacement labor time. This Dorman OE FIX turbocharger water feed line is also made of rubber, but adds in a protective braided steel wrap to prevent damage to the hose for a more durable replacement that helps prevent future leaks. This part is compatible with the following vehicles. Before purchasing, enter your vehicle trim in the garage tool to confirm fitment.
