Does anyone know if the idler pully and tensioner pully are the same thing on the 3.7 V6? Which way do I need to turn the bolt to remove the tensioner pully? Is it a conventional threading or is it reverse?

_________________

The tensioner assembly has 3 bolts,2 of them hold pulley's,one can be moved and one can not.The 3rd bolt holds the tensioner assembly to the engine,it takes a 15mm socket to remove,standard threads(righty tighty,lefty losy).

Neatus; just so you're clear, the tensioner & idler pulley's are not the same.

Should you need to replace, Goodyear Gatorback tensioner pulley p/n 49003, tensioner assy p/n 49246, and idler pulley p/n 49001.

Actually on the 3.7 in a KJ the tensioner assembly has 2 pulley's,one is attached to the tensioner swing arm and the other is a idler pulley.The correct tensioner should come with both pulley's attached.

If I wanted to remove my tensioner assembly I would need a 13mm socket, to remove either pulley requires a 15mm, so I found out this past Friday.

I just replaced the whole assembly since it wasn't that expensive. Thanks all for the info....it is a super easy job.
