thats the way i did it not too bad. i think some have said you can do it from below? i did replace both belts and tensioner i have 150k miles 4K+ hrs. ford tensioners went it great with the pin i wish all tensioners had that.
This is more than likely the fix for anyone who has a squeak/squeal/chirping noise coming left of center on the motor. When listening and looking from the outside, it sounds like it's chirping from behind the left side of the radiator. I had read about the TSB for the idler pulley, so I did that one first(easiest). The noise did not go away. I then replaced the tensioner and belt and it's now quiet as ever, minus my 5" straight pipe
