I don't know about yours, but both my wife's Contour and my Dakota make the
popping sound, not only warming up, but cooling down also. I had a
mechanic say it was from the shield on the cat. converter flexing due to
the change in temperature ( kinda like putting a pan in a stove and it
flexes when it heats). It may be doing the same thing to the spring steel
in your tensioner. Remember how much metal changes size and shape when
you heat and cool it. (Thats how you install ring gears easier, you heat
it a little before hand and it slides right on).
Just my two cents........
