Installation Notes

Verify the hose routing, connector style, and end diameters before installation. Drain coolant as needed, transfer the hose carefully to avoid stressing the fittings, and confirm the clamps are seated correctly after installation. For Tesla S fitment, confirm the build date on 2021 vehicles, since coverage applies only through 1/31/21.
