I've got a coolant leak on a 94 GT and I'm not sure what to call the hose that is leaking. It appears to be leaking from a connection of two hoses, one end of the hose is from the (radiator) and the other end goes into the firewall on the passenger side. Can this be serviced or do I need to replace the entire assembly? It's leaking at the connection near the passenger side header. Any help for parts needed would be much appreciated.
