I don't know about your exact engine, and chances are good that no one who
will reply here does either, but these things are traditionally located in
the hottest part of the cooling jacket, that is to say, it is screwed into
the top, or somewhere near the top, of the cylinder head. Replacement
involves disconnecting the wire to the sensor, unscrewing the old one,
spilling some coolant, screwing in the new one, and reconnecting the wire.
