The Shell station had the car all day Tuesday, looking for a replacement radiator fan relay (I sound knowledgable, don't I?). It's a little piece that is smaller than the palm of your hand. Miracle of miracles, they found one, replaced it, and drove the car to the house. We had time to get groceries before dropping Katherine off at Brownies, and thankfully have the car for parent-teacher conferences Wednesday morning. All is good.
