i just got an alternator put on aboput a week ago. and ever since then my truck has made a winding sound. kinda sounds like an R/C car.. i know hahaha. but anyways i got in it last night, started it up and the sound got really loud and my truck died. i started it again and it idled like it was flooded and it died again. this happened bout 2 more times and then it was okay. im thinkin it maybe the waterpump but its not runnin hot or anything. thankye now
