not totally sure if they are all the same, I would think the 97-00 monteros all had this same part; mine is a 99. it has two different temperature sensors screwed into it. the fitting has 3 openings, one that uses an O ring that connects to a solid metal pipe that goes towards the rear of the engine, the other opening is out the bottom down to the t-stat housing, and the third opening is the upper radiator hose connection.

thanks for any help.

any other sources are welcome, new or used.
