the hole it is leaking from is their as a warning your water pump is going out . if you don't change it soon it will be a big leak
If you are smelling the sweet but unpleasant aroma of antifreeze, your vehicle is leaking it somewhere. A lot of the time the culprit is the water pump. They have a weep hole and when the bearing starts to fail it will begging leaking from this hole. I would start by getting myself a flashlight and start scanning your engine's water hoses for a leak. Check the mail hoses going to/from the radiator as well as the heater hoses leading to the firewall. Do you smell the antifreeze odor INSIDE the car? If so, it could be your heater core that's failing.
It is rare for a water pump to stop pumping, even if they are leaking, they are still pumping as long as the belt is there and tight. I would change the thermostst first. There are a few water pumps out there that have a plastic impeller and I have seen them break apart but that is rare.
Most water pumps have a small vent hole on the bottom side of the pump. Inspect with a flashlight and check for staining (rust or color changes left behind after water runs away from the vent) related directly with that vent hole. Also check for play (side to side) in the input shaft (belt pulley or fan pulley Either of these conditions is an indication of a failed or failing water pump.
Replace water pump.
if the water pump is noisy or it is leaking coolant out the relief hole on bottom of pump.
The most obvious would be coolant leaking from the weep hole. A noisy and or loose water pump bearing would also be a good reason to replace the pump.

if it is not making any noise,or leaking from bottom of pump. Releif hole is on bottom of pump,if leaking replace pump.
Shold be a weep hole underneath stem of water pump. If it's leaking water it needs to be replaced. You will be able to tell.
Noisy, leaking from the weep hole on the bottom of the pump, or engine overheating.
If it is leaking next to where the lower radiator hose attaches to the engine, the water pump has failed. That hole is the water pump weep hole.
More than likely there is a hose with a hole in it. Also, if the water pump is bad it could be leaking.
The bearings can get noisy and you may see the water pump pulley and fan wobble when the engine is running and of course the obvious would be coolant leaking out the weep hole in the water pump.
There is a weep hole at the bottom just under the pulley where there will be a stain of coolant if it is leaking. Or unhook the belt and check the play of the shaft of the water pump.
It could be a bad water pump if it's leaking out the weep hole at the bottom of the water pump.
