Can anyone tell me if the following parts are the same, i.e go into
the exact same location?
These are idler pulley assemblies for a '99 8 cyl Mountaineer. I had
the F7 part replaced, then at later date the F8 part replaced and
dealer states one was the upper assembly (F7), and F8 was the lower.
Therefore I had to pay for the latter repair, as they claim they were
different repairs. I believe that the F8 is just an improved updated
replacement for F7. Other dealers have told me there is only 1 idler
pulley assembly. Both repairs were performed to correct a continual
squealing noise by the belt drive.
