what is the diameter of this pulley in millimeters?

The precise diameter of the pulley tensioner is 3.54" wide x 1.18" deep or 90mm x 30mm ... I just now noticed that this question was posted and even answered 8 yrs ago! .. so I'm hoping that within the 8yrs since the original post the person was able to get the information they were seeking

would like to know if this will fit the passenger and driver side i have a/c and i have a ford 2008 f150 stx 4x4 4.6L extended cab need driver side

I'm not sure why you are asking about if it will fit driver/passenger side because it's just a tensioner pulley. I apologize if I missed something nor am I trying to be disrespectful in any way.. anyhow I hope you got your question answered by the right person. Have a blessed day

Does it a fit a 2007 ford taurus se i seen someone on youtube say it will fit but on here and on dorman's website says it doesn't

Sorry it will not work for that vehicle

what is adjustable on it? and it mentions steel or plastic, can I be sure i get steel?

Not sure why it states steel or plastic. There is nothing adjustable on it.It fit great. No problems installing
