Well, right as I got home last night, I smelled coolant. Right as I pulled into my driveway, there was a puddle forming under the driver's side. Looked up under there, saw it was dripping off the starter, opened the hood, and I have no idea what that thing is called.

It's a + looking hose connector, with a vacume actuator in the middle? The top 90 degree fitting cracked on the seam, venting coolant everwhere. Any idea what it's called, so I can pick one up later?

Heater hose assembly? Goes to the heater core right? It's just a simple tee. The vacuum actuator is there to stop coolant flow to the heater core when its all the way over to cold on the dash.

^^^ Yep. "Heater control valve". Its standard for the plastic to over heat and crack due after time. Easy fix. You can bypass it if it happens away from home by taking the 2 lines that come from the engine and using a 1/2in 1/4 deep well drive socket and hooking them together.

Just like he said. Its acutally better if you by-pass it with the right tubing. Its not only better for your heater system but also better cost wise. you wont hurt anything, the later XJ's 97+ have the systems already like that.

Just replace it, it's like $20 at your local parts chain and takes 10 minutes to replace.
