Hi, the sprinter i just bought had done a water pump recently, so the blokes son replaced it just before i bought it, now i have it i got the car running and when i got back from a 2 minute spin in it, the damn water pump i stuffed again!! It's all wobbly and the fan is on but its like theres a shaft inside that's busted or something. Would this have been included in the new water pump or do you think this is just bad luck and he should have replaced shaft as well? I have a pic of the fan hanging off if someone needs to see it, but cant seem to post it here. Please help!!!
