I don't know what to call this hose "assembly" on my newly acquired '93 SD. I bought the car under the impression that the water pump was leaking but it turns out that it's this hose. It is a tee type. One end comes from the lower radiator. One end connects to the metal pipe next to the thermostat housing. One end connects to another pipe running along the rail. Here's a pic. Hopefully it will clarify things. It would be nice to have a part number for it or at least it's proper name. It looks like I can get a brass T and just use some clamps.
