  Guilty or not – You decide  December 19, 2012  A man recently
complained that his car was overheating. Technicians checked the
gauge on his dash, which read in the normal range, and used an
infrared sensor on the engine. It was at normal temperature. The
diagnosis was that it was not overheated.  The man was adamant
that sometimes he could "smell" that the car was overheated. He
drove away. Sometime later in another town, his engine ran out
of coolant because of a leaking water pump and was ruined. He
blames the first garage for not finding the problem in time. The
difference here is that his sense of smell was probably picking
up hot antifreeze from the leaking pump, rather than his sense
of touch feeling the temperature of the engine.  Who was right
and wrong here?  He was correct that he smelled something, and
the technicians were right that the engine was not overheated.
He was wrong to assume that the smell was overheating, and they
were wrong for not checking further for the smell he complained
of. Ma
