again the car does not over heat when i was going to put water again i notice the radiator was lower than usaul to the day when the resavor was broken could it be the radiator that could be crack or some thing

also how do you know when your water pump is out

Well, you could have a leak in both the resivour and the radiator at the same time. You also could have picked up a bad new one. PINPOINT where this leak is coming from.

Waterpumps usually leak first out of the weephole which is right where the pully shaft meets the body of the pump, on the lower side. When a pump goes out otherwise either the berring goes bad and there is up and down play on the pulley or the vanes break off and it doesn't pump water.
