Yes, the internal parts of the pump can rust, and effect water circulation.
yes and no, if the water pump seals are bad antifreeze will leak from the weep hole on the water pump, but it is possible for the pump to go bad and not leak at all.
You have to replace it. They are designed to leak when they are going bad.
You could have a bad water pump gasket.
It will leak from behind the pulley that runs the water pump. There is also a small hole in the bottom of the the pump case for that very reason. If the shaft seal goes antifreeze will weep from the hole.
If the water pump is bad, it will leak and your car will overheat. If the Power steering pump is broken the steering will be very hard and if the timing belt malfunctions, your car will stop running.
Do you have an exhaust leak? Do you happen to have have an exhaust leak or a damaged water pump bearing?
It all depends on where it is coming from. It could be something as simple as a loose clamp on a hose; to something as bad as a cracked block, radiator, or a bad water-pump. I suggest starting the car, then looking underneath, to see where the water is coming from
You can not, and should not drive a car that has a bad water pump. The water pump pumps coolant through the engine. You engine will overheat and die without a functioning water pump.
When my water pump went on mine, my car would constantly overheat for no reason, there is a safety valve on the pump which lets coolant out of it when the car is running and pressure builds up. You have it pressure tested, the water pump will normally leak externally under pressure.
A bad water pump can cause your car to stall if the bearing has failed or it is causing overheating. A seized bearing will put excessive strain on the engine and stall it out.
My wife's car had this problem. if the leaking is coming from the front of the engine, the water pump is probably bad. If the leak is coming from the right side of the car, your heater hoses might be bad or the core could be shot. If your water pump is bad, plan on replacing your timing belt. you have to move it to replace the water pump and it is just as easy to change it at the same time.
water pumps have a seap hole that will leak when they go bad ,visually inspect this first
