Not so good vibrations.

Vibration: It comes in the form of a working engine, the jarring bumps of rugged terrain, the terrific concussion of missile firing.

When you add all that to the temperature changes that come from the engine heating up and cooling down, it's no wonder the radiator filler neck bolts on some MLRS carriers are starting to loosen.

Antifreeze expands as it gets hot. So if those four bolts loosen, coolant can blow out from under the plate. If you lose enough antifreeze, the engine will overheat.

Check the bolts once a month or so to make sure they stay tight. Report loose bolts to your mechanic. He'll torque 'em to 264-288 lb-in.
