I have a 82 454 with 3 belts an i cant figure out where all the belts go

The tension is spring loaded and you use a wrench or 1/2" drive ratchet end and move away from the direction of the belt tensioner tensions the belt..

OK,

I would first determine where the bolts are for the ac compressor and loosen them until the belt slides off.

Or, I know this may sound goofy, but you can get a breaker bar and socket or a large wrench and turn the crankshaft while putting a large flat screwdriver in between the v-belt and one side of the v of the pulley, and TURRRRRN it slowly until the screwdriver wedged in there actually takes the belt off (with turning).

That's a trick to use, but inspect the belt for damage afterward, or replace the belt if it is damaged in the process, which it usually is not.

Hope that helps.

You can loosen the alternator that should releive the tension on the belt.
When you tighten it again make sure you can only turn the belt 90 degrees then you know you have the right tension.

The diagram for the routing of the belts is on the radiator shroud or on the hood.
Good Luck

What motor and year? If it is the Ej 25 DOHC all the marks are on the cam sprockets except the crank is marked in the block almost straight up, Just a small notch. Good luck and hope this helps. Have a good day.

The other belt has a tensioner and is located under the ac compressor. It takes a 8mm bolt to loosen it.

If you purchase a goodyear replacement belt the diagram is on the back of the sleeve

bring belt tensioner to where all the way moved
make sure you have belt set once you get the tensioner moves over the belt slides the rest way on and tensioner goes against belt
make sure belt is lined up properly
