Review on 🔧 Efficient OTC 6046 Heater Line Quick-Connect Release Tool for GM: Simplify Your GM Heater Line Maintenance! by Robert Aiono

The photo shows this tool on the back of the hose to the right of the firewall, the tool works great. You simply slip it over the hose and pull forward while pulling the leash to release. I learned it the hard way, having recently replaced the oil pressure sensor and removed the brake booster quick disconnect hose without a quick disconnect tool. Of course it wasn't fast, it wasn't fun, it wasn't easy. This tool made it easy to remove the quick connector where my branched radiator hose enters the firewall. Unfortunately, I think I accidentally threw the tool away afterwards as I haven't been able to find it since the job finished. Get it, you'll thank yourself later. I'm on the verge of getting another one.
