I have a tick in my 5.0 and looking through ALLDATA it shows a drive belt kit part # BL3Z-8620-E. It shows this as being a problem area for causing ticking in the early 5.0 because of the lack of tensioner as the OE is straight from crank to compressor. I will probably do this kit just for ease of future belt changes since the kit contains an idler and tensioner pulley. I just wanted to see if anyone has done it or had it done and it helped with ticking. The kit is $106.18 plus shipping through Tasca. Probably take 30-45min to do.
