Hi all, I'm replacing the drive belts on my 95' F350 (460 motor) and have managed to loosen the alternator belt but am having trouble with the other one. It seems that I have to loosen the idler pulley arm? Is that the name of it? Looks like it's secured with just one bolt. I loosened the bolt but that doesn't seem to make a difference. I searched, but couldnt find any threads with my particular question. If they're out there maybe someone could send me a link? Thank you! -Lance

 

You do not have to loosen the tensioner bolt. You use a long wrench to pull up on the arm, it's spring loaded.

Drive Belt Replacement:

Removal and Installation

1. Install a closed-end wrench on the tensioner pulley bolt and lift the tensioner arm away from the drive belt.

2. Remove old drive belt. Release drive belt tensioner slowly. Do not allow drive belt tensioner to snap back after the drive belt is removed because this may damage the drive belt tensioner.

3. CAUTION: Make sure the drive belt is properly seated on all pulleys. One revolution of the engine with an incorrectly seated drive belt may snap tensile members in the drive belt.

Install new drive belt over pulleys making sure that all belt ribs are correctly seated in the pulley grooves.

 

sounds pretty straightforward, thanks!

 

You are welcome. Be careful when relieving the tension on the belt. The spring is pretty stout.
