I just wanted to mention that I first had a problem with leaking
three years ago from one of the front hose connections. I tightened
it, wrote the problem off to having the car up north in 18 degree
weather, and drove on for a year. Then it leaked again, same place. I
removed the hose and saw that the metal was in place but the plastic
around it had split to pieces, allowing the coolant leak. I removed
the broken plastic, sanded the metal, and recreated the missing
plastic and flange out of JB weld, which wasn't have but was like
using a very loose modeling clay. I put the JB weld around the metal
pipe, more or less to the height of the plastic, and wrapped it with
packing tape to make it smooth with the plastic. I came back a second
time and fashioned the flange at the end.
That's been two years and not a drop out of it.
