i just noticed i am missing the lower bolt on my alternator on my 1988 300 ce. so my surpentine belt is not as snug as it should be could this be the reason for my car overheating recently ? appreciate all feedback:

how loose is the serpentine belt?it is possible that the belt was slipping on the fan pulley but not probable.more than likely another issue causing o/heat.fan clutch and radiator more common possibilities[even if radiator doesn't leak age and temperature causes the aluminium tubes to shrink and not flow enough coolant] call me and give symptoms and i will try to help. david poole dallas tx.214-9567007
