Dont know how to loosen or tighten the belt im trying to put on my car. the belt is connecting the alternator to the waterpump

I assume you are replacing the belt and also the waterpump, the waterpump is what tightens the timing belt, it spins in the housing in an oval shaped housing and tightens or loosens the belt, you need to loosen the waterpump bolts and rotate the pump to tighten the timing belt, make sure theres a small amount of slack in the belt after you tighten it, you dont what the belt too tight, you should be able to grab belt and move in and out an inch. heres a diagram to make sure all timing marks are lined up. note if the timing belt is being replaced you really should install a new waterpump and check the timing pulleys. good day.

FOR 3.0LENGIBE. PUTTING ON ALTERNATOR BELT YOU NEED TO LOOSEN LOCKING BOLT IN SLOT IN THE BRACKET.LOOSEN PIVOT NUT BOTTOM NUT USE A PRY BAR PRY AGAINST ALTERNATOR TO TIGHTEN BELT TENSION. BELT SHOULD DEFLECT 1/4 TO 1/2. FOR 2.4L ENGINE TO GET ALTERNATOR BELT ON YOU NEED LOOSEN THE PIVOT BOLT OR NUT AT THE BOTTOM OF ALTERNATOR , LOOSEN THE LOCK BOLT AND TURN THE ADJUSTER BOLT TO TIGHTEN ALTERNATOR BELT THE BELT DEFLECTION SHOULD BE 1/4 TO 1/2 INCH WHEN YOU PRESS DOWN WITH THUMB.

disconnect the positive terminal from battery. loosen belt tensioner to loosen belt. remove harness connection and bolts. remove old alternator, put new one in place. put bolts back on. tighten bolts. plug in harness. put belt back into tensioner, pull it tight so there is very little play in blelt and tighten. reconnect the battery.

to tighten the thin belt, loosen the top and then the bottom nuts that go through to the frame. The turn the bolt on top, the closest to the front of the car, clockwise. Then tighten both through bolts up. For the thick belt, loosen the through bolt on the alternator, then turn the long bolt at the bottom, front of car, of alternator clockwise.

it isnt that hard actually

disconect positive battery terminal. and feel the tension on the laternator belt. you will need to bring it back to this tension.

1.) loosen bolts holding alternator in place (LOOK AT THE BELT TO REMEMBER HOW IT GOES, BEST NOT REMOVE THE BELT.)

2.) loosen bolts holding wires to alternator and connect wires to new alternator

3.) Place alternator in engine, replace bolts but dont tighten

4.) put belt in place, it will be slack, use your tire iron or a piece of pipe or wood to pry the alternator back, to bring tension on the belt. You pry the alternator to pull the belt as TIGHT AS POSSIBLE. while holding strain, on it, tighten the bolts.

You should have a tensioner pulley somewhere in the belt's path. It will be mounted to the engine but not connected to anything. You need to loosen it and swing it in towards the engine to install the belt. Once the belt is in place, pull the tensioner to the outside and tighten it, but leave some flex in the belt. If the pulley wobbles or whines, you'll need to replace it, too, or it will destroy the new belt.

NOTE: If the belt still won't go on with the tensioner released, the parts guy may have sold you the wrong belt.

loosen tensioners using a pry bar or equivalant and loosen tensioners on ac and alternator then tighten when replaceing. work on outside belt off fist and then inside belt off second. then install inside belt first and then outside belt. you will see a grooved hole where the bolt goes through the alternator to reduce tension.

Unbolt the pulley from the water pump, slip the belt over everything and refasten the the pulley to the pump while the belt is draped over it. Then tighten up the belt.

You should see a slider bracket on the P/S pump. Loosen the upper and lower bolts and with a pry bar, shift the pump to tighten the belt.

Under the alternator is a lock bolt. Loosen the lock bolt and there is a long threaded bolt. With a socket wrench turn the bolt clockwise and the belt will tighten up. After you get the belt where you want it, tighten the lock bolt back up. The lock bolt has an unusual head on it. It will look different from the others in that area.
