This isn't to bad, I've had some good luck with my all my vehicles. Diving down the highway at 80mph in my 86 Silverado, hear a real loud thump, see something black shoot off to the side, whole truck is now vibrating like a $2000 electric massage chair. Assumed it was a tire blow out, pulled over first place I could and looked the whole thing over, little drip of antifreeze but nothing else. Home was a couple miles away, so I took it easy. Got there and immediatly popped the hood and started checking the whole truck over. Finally fter about 15 minuets I happened to bend way forward ( tall truck ) and look down through the fan, whole bottom of the fan shoud was gone, checked the fan, one blade had broke off and shot straight through the bottom. Any place else in the rotation would have sent it through some part of the hood or fender. Antifreeze leak was the water pump taking a fatal blow from vibration, it did last a few more months though.
