[s-cars] Coolant leak and Servotronic

When mine leaked (happened in the winter) I replaced my pump with a
1/2" barbed hose hot water rated PVC elbow.  I replaced my pump with
one (an AAN one) from someplace (recall is not great here, sorry)
called Mountain Auto or Mountain Audi from Boulder for about $100,
although that was in 2004 dollars not our current wimpy ones.  As I
recall, there is a M-B pump which is essentially the same part for
less than the AAN pump, but if the Autoparts Warehouse price is about
$97, I'd go for that just to save the connector hassle.
