Dorman Turbocharger Line Replacement Kit Compatible

In this review the Dorman 667-023 Turbocharger Line Replacement Kit is evaluated for owners replacing a turbo on compatible Buick and Chevrolet models. The bottom line: this kit is for DIY mechanics and professional techs who want a complete, application-specific set of lines and connectors to avoid piecing together parts; it replaces old coolant and oil lines and includes an upgraded corrugated stainless oil return to reduce leak risk. The kit's completeness and the one-package convenience are the single biggest reasons to buy it for a thorough turbo job.

Key Features

• Complete kit: Contains all application-specific lines and connectors needed for a full turbo line replacement, saving time sourcing parts separately.
• Upgraded oil return: The oil return is made of flexible corrugated stainless steel with aluminum connectors to resist leaks better than the original plastic line.
• Application-specific fit: Lines and connectors are engineered to precise specifications for specified Buick and Chevrolet models to help ensure a reliable installation.
• Cost-effective solution: Bundling the oil feed, return, coolant feed and return, and cooler assembly helps reduce labor and parts costs during turbocharger repair.
• Try-on tested components: The included lines are try-on tested to match the required routing and connections for the covered vehicles.

Who It's For

This kit is ideal for owners of compatible Buick Encore and select Chevrolet models who are performing a turbocharger replacement and want a single-package set of all necessary oil and coolant lines. It suits both experienced DIYers comfortable with engine work and independent shops looking to streamline parts sourcing.

It is not intended for vehicles outside the listed applications or for buyers who only need one replacement line; those users should confirm fitment in the garage tool and consider purchasing a single replacement line or OEM components instead.
