Need a little help from the Ford experts here....the Ford forum members didn't respond. I have a 2014 E250 van with the 4.6. It has a/c and I am hearing some high pitch squealing under the hood now and then and I am pretty sure it is one or both of the pulleys (idler and tensioner). I've replaced the alternator and belt last year, no squealing afterwords. Using RockAuto for part numbers, can you guys confirm which parts I need? Is it OK to just replace the individual pulley and reuse all existing hardware (and tensioner arm)? Is installation pretty straight forward or is there anything unusual like reverse threads or special tools, etc.?
Here is what I am looking at:
Idler - ULTRA-POWER 38001
Tensioner - DORMAN 419610
Thank you
