Product Details

Installation Notes and Tips
Verify end diameters and centerline length against the removed hose before installation. Confirm routing at the heater outlet on the Kia Optima and inspect adjoining clamps, fittings, and nearby hoses for wear or contamination. Proper alignment with the molded shape helps maintain clearance and reduce stress on the connection points.
