Continental 64458 Engine Coolant Bypass Hose

Universal Straight Engine Coolant Bypass Hose

Continental Universal Straight Engine Coolant Bypass Hose Part Number 64458 is a cut-to-fit coolant hose for custom routing and replacement applications where a molded hose is not available. With a 1.250-inch inside diameter and 36.000-inch length, it supports straight-run coolant connections across a wide range of vehicles, including Cadillac XLR, Nissan Xterra, and Toyota Corolla applications.

Measure the required routing length before cutting the hose to fit.
