Easy fix, put rachet or breaker bar on idler pulley centerbolt and pull to the side allowing enough slack to remove old belt. Install new one and release idler to original position careful to not let spring return too fast and skin knuckles! Goodyear gatorback is a good replacement.

Place a 13mm box wrench, on Idler Pully/Tensioner center bolt, and SLOWLY turn clockwise, just until you can slide Belt off Power Steering Pump Pully(PSPP).
Carefull, you can damage Tensioner housing, if you turn too far!!!

Route new Belt per diagram on radiator support, leaving belt off PSPP.
Now, SLOWLY turn center bolt clockwise again, just until you can slip belt back on PSPP. You're done, EASY.

Agreed.

I've found that if you put the box end on the tensioner bolt with the other end pointing at the balancer horizontally and pull/push down (I do mine from the bottom), that it works best without cutting knuckles on hose clamps and other stuff. So, if you're looking at the tensioner, the wrench will start off pointing at 3 o'clock, and it will be pointing at 6 o'clock when the belt slides off.

The Tensioner's cast housing, is fairly fragile.
You can determine if housing is cracked, by crawling under car, and eyeballing both sides of Tensioner[If broken, you'll see the end of Tensioner's spring sticking out side of housing].


So remember: Slowly turn 13mm center bolt, ONLY till Belt slides off {& on} PSPP.

buff my alt is the highest accessory as well, my car is the b4u towing package with the mech fan belt. also the tensioner used a 9/16 not a 13mm.

My belt removal suggestions were assuming you had "Dual Electric Cooling Fans".
Most B/D-Bodys were equipped with this setup.

In the future, please specify you have Mechanical Fan[V08-HD Cooling/Towing Package] setup, if your questions pertain to front engine.
You may want to add this info, in your Sig.

I like the Dayco Polycog design - seems to handle flexing a lot better and provides better belt cooling. Advance carries it, among others.

When I swap the belt, I go under the car, stretch the tensioner, get the belt loose from the pulley or the crank (if the car's got a mechanical fan). Then I go from above and unthread the old belt, put the new belt on, then leave the tensioner or crank loose, pull the tensioner in and install the belt. I then slowly release/apply the tensioner a few times to make sure the belt is properly seated, visually check it, and go.

The electric-fan cars are easy as pie. It doesn't get any easier than an electric-fan B-body!
