Question about 1996 GMC Suburban
Have a 1996 gmc suburban k1500 1/2 ton 4w auto, the belt started squealing a week ago and have noticed the dash indicator needle dropping to about 10 on the amp gauge at idle speed at times. when on the road the needle is on the center of the gauge(14) also notice that the head lights are dim while idling or coming to a stop. also have hesitation at night during acceleration when the engine is cold. while driving during the day everything seems fine. just replaced the alternator but still have the same.the battery is 2 years old checked the cables. replaced the belt last spring the same time i put on a A/C comp by-pass pully (a/c compressor pully stated making noise and never worked) i believe i replaced the tensioner 2 or 3 years ago.truck starts fine what else should i check.
