Radiator mounted condition sensing probe

Apparatus for installing a condition sensing element in a heat exchanger of the type having a plurality of cooling fins extending between first and second opposite sides, and elongate spaces each extending from an opening in said first side to an opening in said second side between adjacent ones of said cooling fins, said apparatus comprising:

• an elongate probe comprising said sensing element and having exterior dimensions substantially equal to a first one of said spaces so as to contact the cooling fins on either side of said space, said probe having first and second ends which protrude from said first and second sides, respectively, when so inserted;
• a thin, elongate member dimensioned for insertion through a second one of said spaces, and having first and second ends which protrude from said first and second sides, respectively, when so inserted;
• and
• retention means for (a) connecting said first and second ends of said elongate member to said first and second ends, respectively, of said probe, and (b) retaining said probe and said elongate member in said spaces comprising first and second retention elements, each of which includes a rigid member having a surface facing said heat exchanger adapted for attachment to said first and second ends, respectively, of said elongate member, at least one of said retention elements being longitudinally moveable on said elongate member toward the other retention element so as to cause said first and second retention elements firmly to engage said first and second sides, respectively, of said heat exchanger;
• a resilient pad adhesively attached to each of said surfaces, respectively, and having area sufficient to cover the openings of a plurality of said spaces at least adjacent to said first one of said spaces;
• and locking means for locking said first and second retention elements in engagement with said first and second sides, respectively, of said heat exchanger.
