[s-cars] leaking coolant

I have extensive experience in leaking S4's!
I have a pair and both have 185-190k. I have found that both vehicles
developed a leak in the after run coolant pump at around 185k. Both leaked
out of the heater hose goose neck at the rear of the head at about 170k.
One of the cars leaked from the coolant manifold under the intake (that one
was hard to find). I have always been able to pin down the location of a
major leak by looking for wet spots beneath the car and tracing the water
upward after it sits after a good hot run. Minor leaks require a dye test.
