I'm not really sure how to describe this other than posting a picture and hoping for the best. I have a 2005 MTX 3.0 and I have tried home depot/autozone and neither said they had it. I broke a little elbow/fitting that was used in the water/coolant lines and I need to order a new one, but I'm not sure where to buy one or what it's even called. I could always take it to Mazda I suppose. Here is a picture of it. It's that thing there in the middle and I broke the side that has the small hose running to it. If it would help I can also get a picture of it now that it's removed.
