I know, both are new and the engine does get warm at the pipe plug location in the left cylinder head (as checked by an infrared heat gun). I feel this is where my sensor should be, not at the mixer in front where constant cold water enters. Not sure why it's there, but I really should relocate it to the cylinder head to see if I get a more steady temp reading. Maybe the owner before me put it there, not sure.
