Well, my car just got out of the shop from having both intake manifold
gaskets replaced.  Fortunately, I found the problem only about 1 1/2 months
ago, so they haven't been leaking all that long.  However, in the process of
removing the front intake manifold, the steel coolant line that runs from
the water pump, around the trans. side of the engine and to the firewall
(and I think to the heater core), must have been bent a bit and developed a
pin hole right in the bottom 90 degree corner where it turns to go toward
the back of the engine, right below the upper radiator hose inlet.  This
line had a few rust spots on it where the paint is chipped off, plus the car
has nearly 300,000kms, so I cannot blame the person who repaired the
gaskets.  I just wish it had leaked while it was in his shop and not after I
drove it 60kms to work and had to call a flatbed to get it home.  I called
the dealership to get a price on this steel line (dealer item only), but the
parts clerk was not sure which line I was talking about.  He said it could
only be one of two lines, and the most expensive was $150, which IMO, is
completely outrageous.

A link to a photo, the red arrows point to the line I'm talking about:

What I want to know is what this coolant line is called, so I can do an
internet parts lookup.  I know I'll probably find it about 1/2 price online
of what the dealer wants.  For now, the line is repaired with a piece of 5/8
ID heater hose with 4 hose clamps.  In order to get it on, we had to cut the
pipe with a dremel tool.  The fix is working ok, but I'm not sure how much
pressure that line has on it, and the rubber heater line is not far away
from the heat shield on the manifold. like maybe 1/4".  It will probably
last for a while, but if I can find a replacement steel line for a better
price, I will replace it.

Any help in naming this line is greatly appreciated.
