Water leaking out of small hole bottom of engine

Confirm that the leak is not from the pump.. With the engine cold and off, clean all surfaces which are wet. Make sure the top of the engine is not wet as well. Start engine and look for where the leak is using a flashlight. Be careful of moving parts.
Water pumps have weep holes that leak when the pump bearing is faulty, small holes on the top/bottom of the pump. Also look for leaks from the hose connected to the pump.

There is a small hole (called a weep hole) on the underside of the water pump. Coolant will leak out of this hole when the water pump goes bad. Verify the leak and replace the water pump

There is a small weep hole in the bottom of the water pump. If the seal starts deteriorating it can cause coolant to leak from the hole. Change the water pump and all should be well.
If I helped, please rate my answer and leave a comment. Thanks.

The water pump is in the center of the engine. It usually has a small hole in the casting on the snout. If the seal went bad water usually runs out of the small hole and down the center of the front of engine. With the engine OFF, put your hand under the pump, and feel the snout to see if water winds up on your hand. If possible use a flashlight and check for a leak all around the pump, and bolts that hold it in. In a rare case the pump gasket could be leaking. If the pump appears to be dry, check the small hose that goes from the center of the pump to the block.

Yes.

There are products out there like stop leak that MIGHT stop the radiator leak. However... the only real repair is either to have it soldered (if the end caps are not plastic) or replace the radiator all together.

Adding a product like "Stop Leak" most often starts to introduce other problems to your vehicle like a future water pump seal failure or clogs in the smaller water passages in the engine block, heads and manifolds and the thermostat heater bypass hole. Anyone that has ever done any major engine repairs will know immediately if stop leak was used in a cooling system.

The best fix is to replace the radiator.

Many radiators today can not be repaired

Stop leak is in most any auto parts store. Just be advised of what you can expect down the road.

specifically

1. warmer than usual engine operating temps
2. water pump seal failure
3. heatrer core clog (no heat)
4. passenger heat control temp valve clog (no heat)
The choice is yours. Personally I would not do the "Stop Leak" treatment attempt. Sometimes it works other times it does not.

If it is the water pump it will have a rad hose attached to it. There is supposed to be a small hole in the bottom of the water pump. When it starts leaking, it's time to replace the pump. You can do it yourself. A few wrenches and a couple hours is all you need. If you are unsure pick up a Haynes manual for your car when you get the new pump.

seems u have a blown head gasket or cracked head!

THE OTHER HOLE is actually the drain hole when you open plug it comes out that hole. you should be able to get a new plug at any parts store

yes thats the weep hole it leaks when your water pump iner seal starts going bad,
