Actually some of this tensioners have a square hole, just insert a ratchet and holld it to one way until belt removed, then do the same with the installation, if not square hole then some have like a 18 metric nut to turn with a wrench

Im trying to change the altinator in my 2003 silverado v-6. i took the two bolts out the electric componets and still cant get it loose.

Hi: !st Thing you need to do is disconnect your negative battery cable to prevent more damage.If i'm understanding you Right you Took the Wiring off the Alternator.Or did you Remove the Mounting Bolts? Here Goes Disconnect Battery, Loosen the Bolt on the Alternator Adjuster Bracket, This will give you Some Slack in the Belt ,BUT Locate the Belt Tensioner take a Breaker Bar or The Correct Size Boxed in Wrench or use a Ratchet and Socket. The Tension Is Spring Loaded to Keep Your Belt From Coming OFF. Your Belt Runs Probally Everything like your Alternator ,Water Pump,A/C Compressor,Power Steering So On. So Until you Take the Belt Either OFF or Just Release the Tension on the Belt,I'm Sure if you Have Removed All mounting Bolts and Your Wires to The Alternator, Your Alternator Will Come on Out with a Little Light Effert. Be Sure You Watch How Eveything Comes Off Cause You'll Have To Reverse the Way you Took It Off To Put it Back Together. Be Sure You Look At the Belt Routing Diagram Which is on either your Cross bar By The Radiator. Its Say Belt Routing Diagram. Hope This Gets you Going It Should.If You Follow These Instructions. Please Let Me Know how My Advice Helped You By Voting And Also You Can Send me A Message on FIXYA. From The WYOCWBOY

I need to change out the alternator on a 2002 E150 Cargo Van How do i loosen the tension pulley so that the belt will be released?

Most are spring loaded. If it has a bolt on the front of it, use a socket wrench and press it down and that should compress the spring and should create slack in the belt.

The tension is set automatically with the belt tensioner. It looks like a pulley. You put a wrench or socket on the bolt in the center of the tensioner and apply pressure. It is spring loaded. As you apply the pressure it will release the tension on the belt for removal or installation.

Replacing the alternator belt on 2001 kia spectra

Then you don't take anything off. There will be a spring loaded idler that tensions the serpentine belt. Take a socket or long 12 point wrench and attach to the center bolt of the tensioner, then rotate the idler wheel away from the belt, take the belt off. Slowly release the spring tension of the idler.
The 2nd belt should be set up the same way.

How to loosen the serpentine belt

If you look at the spring tensioner on the belt, there is a 3/8 square hole in the support arm.
Use a ratchet wrench, or breaker bar in the hole, and release the tension. Once it's loose, you can remove the belt.
