Worked perfectly. I used this since I’m not running a heater

The included clamps were tossed. I put these on my fox body coolant thing to just loop it and bypass the heater core

2005 Suburban. The heater hose setup on GM vehicles is a fatal flaw. Have had lots of leaks and breaks on the heater hose connectors at the firewall. One plastic connector broke on the road and lost all coolant. Got that somewhat under control, but still minor loss of coolant somewhere. I bought this for insurance incase the system goes again and I am on the road and need to self rescue. Keep it in the car with tools to install. This allows you to bypass the heater coolant lines in the engine compartment so the vehicle can be driven. Obviously need to carry coolant, but do not put in screaming hot. Let cool first.
