Detailed Description

This Dorman turbocharger coolant line is engineered as a direct replacement for the original BMW line on select turbocharged models. The line measures 6 inches in centerline length, with a 0.125-inch inside diameter and 0.3-inch outside diameter, and uses a 14mm x 10 threaded fitting diameter at end 1. The molded assembly design helps maintain the original routing and connection style, while the stainless steel material supports reliable performance in a high-heat engine bay environment. If you are replacing a worn or damaged turbo coolant line on a BMW 335i, 435i, or M2, Dorman 667-317 provides the correct OE-style fitment for the specified supply position.

What It Helps Address

• Coolant seepage from a cracked or corroded turbo line
• Loss of proper coolant flow through the turbocharger supply circuit
• Fitment issues caused by a bent or mismatched replacement line
• Service concerns from aging factory coolant plumbing
• Restoration of original routing on turbocharged BMW applications
