URO 11537558901 Turbo Coolant Supply Line Cylinders 4-6

The URO 11537558901 is a direct-fit replacement turbo coolant supply line designed to restore proper coolant flow to the turbocharger serving cylinders 4–6. This line is a critical component of the turbocharger cooling circuit, delivering coolant from the engine's cooling system to the turbocharger center housing to prevent heat soak, bearing damage, and premature turbo failure.

URO Parts engineers this line to match the original equipment specifications, ensuring correct routing, fitment, and sealing. Over time, factory coolant lines can crack, harden, or develop leaks due to constant heat cycling—symptoms that can quickly lead to coolant loss and turbocharger damage if left unaddressed. Replacing the line with a quality aftermarket unit like this URO part restores reliable coolant delivery and protects turbo longevity.
