That's what I thought. The original coolant is green, the heavy rust color
indicates it's now mostly water. It's very likely this is only the tip of
the ice burg. Expect the soft plugs to be a future problem. The radiator and
heater core are most likely filled with rust deposits, which I doubt very
much a flush of any kind will help. Look at the nipple very closely, I'll
bet you find it did not shear off, it rusted to the point that it fell
apart. The nipple is for cooling the EGR valve, there are two of them. They
are long enough that nothing is going to sheer them off. Fixing the major
problem is the whole cooling system. So $1300. dollars if the car is
important enough to you might be justified. But you have to look at the
hidden damage the rusty coolant has caused, something to think about.
