Installation Notes and Tips

Ensure the vehicle is cool before removing the old heater hose to avoid burns. Verify the 5/8 inch inside diameter matches the existing hose connections. Inspect hose clamps and replace if necessary to secure the new hose properly. Routing should follow the original path to prevent kinks or contact with moving parts. No heat shield or protective sleeve is included, so confirm the hose routing avoids excessive heat exposure.
