I usually hold my breath when changing the pully, but some folks need air or they'll pass out.
There should be a spring loaded tensioner pulley. If the pulley isn't holding the belt sufficiently tight you may need to replace the tensioner.
To change the alternator belt on a Mazda 323, first remove the right hand air shield under the can. Then locate the pulley tensioner of the AC and loosen the bolts on the pulley. Finally, remove the alternator pivot bolt under the alternator to remove the old alternator belt and replace with a new one.
THERE IS A BELT TENSIONER BELOW AND JUST TO THE RIGHT OF THE FAN PULLEY. LOOSEN IT COMPLETELY, AND THE NEW BELT SHOULD FIT RIGHT ON. THEN TIGHTEN THE TENSIONER TO TIGHTEN THE BELT, AND YOUR DONE. GOOD LUCK, DANNY.
Loosen the 17mm bolt in the middle of the pulley. Loosen the belt tensioner, and the pulley should slide off with a little help. Make sure to nothing the little key-way that lines the pulley up.
right side / pass. side has mark on outside rigtht and left has it on outside left, a arrow shape in the metal. bottom crankshaft pulley is 12 o'clock top center. i believe you need to repklace tensioner when doind tim belt replacement and i have been struggling to get the belt on due to cannot push back the spring loaded tensioner pulley. may be a stuck tensioner.
Most likely there is a spring loaded device called a belt tensioner. There is a pulley on it with a bolt or square inset in it. sometime a socket or 3/8" drive extention can be used to move the pulley and release the tension on the belt.
in your face :)
On a v6 you need 5quarts
I just did it. 5 qts.
Check all belt driven accessories (alternator, P.s. Pump, water pump, idler pulley, belt tensioner, etc.) to find which is frozen and replace appropriate part
Should be the tensioner that the Alternator belt goes to
I will assume you are regarding the pulley for the power steering? If so to loosen it use a socket on the top of the pulley it should have a flat head style appearance.Loosen it clockwise and then the big nut on front of the pulley is a 7/8 inch combination wrench loosen it and the pulley should slide down to make the PS belt loose.This pulley is kind of weird but,by loosening the top bolt (metric) the bolt will come up as you take the tension off.Then YOU defenitely have to loosen the nut on the front of the pulley itself which alloys the pulley to move up or down.To adjust back with new belt on run the top bolt which is behind the pulley with the flat head cut in it run it down tight then tighten the nut on front of the pulley this locks the pulley in place so it will not move.Hope this helps.If this question is in reference to the tensioner for the timing belt resubmit your question.
