1999 Chevrolet 1500 Pickup Question: Broken heater hose connector at the firewall
The heater hose connector at the firewall of my 2000 Silverado (1500) broke off at the heater hose connection. The plastic nipple broke off at the clamp site while I was driving home and the coolant ran out. The low coolant light came on and the temp lite. I stopped before any damage was done, but I can't figure out what I need to do to replace the broken connector.

It seems to turn but it won't unscrew and I am afraid to pull it off before I know what I am doing. - visoria1
