I am planning to replace the serpentine belt along with the idler pulley and belt tensioner on my 2001 E 350 with v10. I can bring the belt to the parts store to double check the length. I want to buy the idler and tensioner online and I am looking at Motorcraft as the brand because I think they are the best quality for the money??? (I'm open to other suggestions on brand) Does anyone have the part numbers for the idler and tensioner for this year van and engine? My search brings up multiple Motorcraft options for both the idler and tensioner which seems odd.
This is what I found on Amazon. If anyone has a better suggestion on part brand or part numbers they have used with success I would love to hear it.
Idler: (Motorcraft part number YS250) This part is $52 at local parts store and $25 on Amazon. There are a bunch that are listed from Motorcraft as compatible.
Tensioner: (Motorcraft part # BT45 or BT62) BT45 is grooved and BT62 is not
Any guidance is appreciated for this novice. I want to do as much of the engine work myself to help me learn about the van and how to fix it.
Also planning to replace the front axle u joint and upgrade the quigley torque arms in the near future. I have read some threads here on the torque arm replacement and that seems pretty straight forward.
