Thanks for the tip.  My pump started making noise at Bodega Bay on Highway 
1.  We were staying south of Napa which was 50 miles.  Made it back without 
incident, luckily, and we put the car on the trailer and headed home (well, 
after spending another day in Napa Valley driving the Escape).  

Someday soon I will order up a new pump and pulley and some Locktite RC609 
and hope for the best.
