Dorman Turbocharger Coolant Lines

Dorman offers turbocharger coolant lines designed to match fit and function of the original line on specified vehicles. They are engineered for durability from high-quality materials to serve as a reliable replacement for a leaking or failed original line. The purpose of turbocharger coolant lines is to circulate coolant through the turbocharger to prevent it from overheating, which protects the turbocharger and its lubricating oil. This is especially important after the engine is turned off, as it allows for natural convection that keeps the turbo cool without the engine's water pump running, preventing oil from coking into a harmful residue. By maintaining stable, lower operating temperatures, coolant lines reduce thermal stress on the turbocharger and surrounding parts, such as hoses, seals, and gaskets, helping to prevent material fatigue, warping, or cracking to ensure longevity of the turbocharger and engine components.
