How do you replace the alternator on a 1991 Pontiac Sunbird?

Answer 1

REPLACING THE ALTERNATOR ON THIS MODEL IS VERY EASY. TO START DISCONNECT THE BATTERY COMPLETLY. NEXT, REMOVE THE DRIVE BELT SIMPLY BY PRESSING DOWN ON THE TENSIONER. THERE ARE 3 NUTS AND 1 BOLT HOLDING THE ALTERNATOR DOWN. 2 NUTS BOLTING IT DOWN TO THE HEAD BOLTS, 1 NUT BOLTING IT DOWN TO THE INTAKE MANIFOLD, AND 1 BOLT CONNECTING IT TO THE POWER STEARING BRACKET. TAKE ALL 4 OUT. REMOVE THE 2 WIRES FROM THE ALTERNATOR. DONT LET THE POWER TOUCH METAL OR (*SPARKS*). NEXT TASK IS TO REMOVE ANY BRACKETRY FROM OLD ALTERNATOR. AFTER PURCHASING A NEW ALTERNATOR (WHICH I WOULD SUGGEST) BOLT BACK ON THE BRACKETRY THAT YOU TOOK OFF OF THE OLD ONE. THERE WILL BE A PIVOT BOLT ON THE ALTERNATOR THAT MAY BE DIFFICULT TO GET OFF. WHEN YOU PUT THIS BOLT BACK INTO THE NEW ALTERNATOR LEAVE IT LOOSE AS THIS WILL BE A WAY OF ADJUSTING THE POSITION OF ALTERNATOR. PUT ALTERNATOR BACK IN AS IT WAS TAKEN OUT. CONNECT THE 2 WIRES BACK IN. ADJUST AS NEED (WITH THE PIVOT BOLT). PUT ALL NUTS AND BOLTS BACK IN. PUT DRIVE BELT BACK ON ROUTING IT PROPERLY. MAKE SURE IT IS NICE AND SNUG. PUT BATTERY BACK IN AND START HER UP! GOOD LUCK.
