A water pump with bad bearings can cause this. I just experienced this on my 2003 Buick. All other belt driven components, i.e. a/c, alternator, Power Steering unit, tension pulley, etc were free turning. Water pump shaft was locking up and threw belt off.
If you mean the serpentine belt by "bands" than I would guess that it's the water pump. I had a bad coolant leak on my 97 SL2 and diagnosed it as being the water pump. It was leaking right from the pump, which is towards the bottom of the engine. Look at the diagram for the serpentine belt under the hood and see if that could be where it's leaking from. Hope that helps.
Yes water cause leaking
Antifreeze? Water pump?
Where is it leaking from? Could leak from the radiator, hoses, or water pump.
If the belt is too loose or not there then yes - the water pump runs off the serpentine belt. If the belt is too loose or not there then yes - the water pump runs off the serpentine belt.
maybe your radiator is broken and you need to get a new one or just get a reparation if the radiator starts leaking when is in use it may be leaking because of the pressure of the water.
No, low coolant would cause the opposite.
There is likely a crack in the engine block.
The only water that should be leaking from an automobile would be from the condensation drain for the Air Conditioning or from condensation out the exhaust pipe.
Could be that your heater core is leaking May also have a plugged evaporator hole.
It could be the heater core leaking.
If the front seal on the pump is leaking this usually indicates the pump is bad. I recently had the same problem. It is wise just to replace it. If it is not replaced soon it will cause excess tension on the serpentine belt which could cause damage to other accessories that run of the belt.
