Detailed Product Overview

This turbocharger line kit is designed for service on the turbo oil feed, oil return, coolant feed, and turbo coolant line circuits. The pre-shaped design helps the replacement lines follow the original path on the truck, which is important when servicing turbocharger plumbing on 2002-2004 Chevrolet Silverado 2500 HD and Silverado 3500, as well as 2002-2004 GMC Sierra 2500 HD and Sierra 3500 models. Dorman 667-066 is a specific-fit solution for vehicles listed in the fitment data and cross-references OE part numbers 97188654 and 97230093 for the same application.

Common Problems This Kit Can Address

  • Oil seepage or leakage at turbo supply or return lines
  • Coolant loss from damaged turbocharger coolant plumbing
  • Corrosion or fatigue in original turbo line assemblies
  • Poor fitment from bent or mismatched replacement lines
  • Service issues caused by worn seals or gaskets at the turbo line connections

Installation Notes and Tips

Verify the vehicle year, make, model, and turbo line routing before installation. Compare the original line shape and connection points to the new pre-formed components, and inspect adjacent seals, fittings, and mounting points for wear or contamination. Because this kit is specific to listed Silverado and Sierra diesel applications, confirm the exact engine and turbo plumbing configuration before beginning service.
