So I bought a 95 Z71 from a guy that had been sitting in a field for a while. Had it a few months but hardly drive it. Started it the other day and took it out for its longest trip yet, approximately 15 miles. It ran hot and when I popped the hood it was pouring water/fluids out of the hose that connects the heater core to the firewall. Anybody know what that hose is called, its probably have hose and the other half is like an aluminum material. Any help would be appreciated.
Thanks
