  • Direct-replacement kit for specified Buick and Chevrolet turbocharged vehicles
  • Includes oil feed, oil drain, coolant feed, and coolant return line components
  • Application-specific fitment for 2011-2021 models listed below
  • Upgraded Dorman OE FIX turbo oil return line with corrugated stainless steel and aluminum connectors

Detailed Product Overview

This Dorman 667-023 turbocharger coolant and oil supply/return line kit is engineered for thorough turbo service on 2013-2021 Buick Encore, 2013-2021 Chevrolet Trax, 2012-2020 Chevrolet Sonic, 2016 Chevrolet Cruze Limited, and 2011-2015 Chevrolet Cruze. The kit brings together the key oil and coolant transfer components needed during turbocharger replacement, helping restore proper fluid routing with parts matched to the original application. The upgraded 667-520 OE FIX turbo oil return line uses flexible corrugated stainless steel with aluminum connectors for improved durability and better leak resistance than the original plastic design. Part number 667-023 is a practical choice when servicing turbocharger lines on Cruze, Sonic, Trax, and Encore models.

This part cross-references Rotomaster K1040310N for the same application.

What It Helps Address

  • Oil leaks at turbocharger feed or return line connections
  • Coolant seepage from aging turbo coolant lines or fittings
  • Cracked or brittle factory-style plastic return line components
  • Incomplete turbocharger replacement repairs that leave old lines in place
  • Fitment issues when replacing worn turbo oil and coolant routing parts

Installation Notes and Tips

Verify engine and turbocharger configuration before installation and compare the original line routing, connector style, and threaded fittings to the replacement parts. Because this kit is application-specific, it should be installed on the listed Buick and Chevrolet models only. Inspect mating surfaces, seals, and adjacent turbo hardware during service, and replace any damaged connectors or sealing points before final assembly. Part number 667-023 is intended for professional-style turbocharger line replacement where a complete oil and coolant line refresh is required.

Quality Assurance

Dorman supplies this kit as a direct-replacement service solution with try-on tested components for the listed applications. The OE FIX turbo oil return line adds a stainless steel and aluminum construction upgrade for added durability in the return-line path.
