There are TWO identical pulleys used for the idler and tensioner for
the INNER serpentine belt ( AC ), and both have flat smooth surfaces.
When I tried to buy replacments for these, the parts people tell me
they aren't listed, and try to give me the OUTER ( much wider )
tensioner and idler pulleys.
1) What gives here? Is the wider pulley( smooth ) meant to be a
replacment for the narrower one? It seems to me like this not correct.
Is this a dealer only item?
Any thoughts on this?
