Review on 🔥 ACDelco Professional 18221L: High-Quality Molded Branched Heater Hose for Expert Heating Applications by Juan Axum

Interesting hose. It fits my car perfectly and conforms to all the original curves. WARNING: You can do a little research on the GM heater hose. The GM uses a fast connection on the firewall to connect to the heater core. You may need a new connector, e.g. B. a Dorman 800-409 heater hose connector (connector on my model. There are others) and you will definitely need a HOSE TOOL CLAMP to remove the plastic connector. Examine the connections. There are many videos showing how the plugs can break off with age. I have decided to replace mine. The tool that matched my connector was OTC 6046 Heater Line Quick-Connect Release Tool for GM. Most local parts suppliers tried to sell me an undersized AC tool. Lubricate the tool with some lubricant before inserting it. My hoses burst right away.
