The turbocharger coolant line on certain Ford and Lincoln vehicles often rusts and leaks at the junction point where it meets the quick disconnect fittings. 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 nine hours of replacement labor time. This Dorman OE FIX turbocharger water feed line replaces the OEM regular steel line with a stainless steel line for a more durable replacement that helps prevent future leaks. In addition, this is a complete kit to service the turbo coolant lines, including the supply line, return line, connectors and turbo mounting gasket. This part is compatible with the following vehicles. Before purchasing, enter your vehicle trim in the garage tool to confirm fitment.
