Not sure where exactly the water is coming from but positive its not the pump nor radiator. we have checked all the hoses and havent seen any leakage there either. it seems as though the water is leaking from the front of the transmission around the little pipe that connects it to the motor. if the jeep isnt running it doesnt leak. but once its started and warms up it is a really steady stream whether it is moving or not. please help it is our only running car and i have to use it for dr.'s appointments for the kids and school and work . thank you very much in advance. heather
Freeze plugs checked they are fine all 3 of them. and nope the air conditioner isnt running. example: if i start it and let it idle it will leak visibaly but not a steady stream. after the motor starts to heat up the stream gets bigger and bigger but no gushing. oh and i forgot to mention the water is just water not other fluids in it. not to sound stupid but im not sure about which of the hoses are heater and radiator but we checked them all. there is a plate covering the face of the big end of the transmission and a pipe coming out of it and looks as if it is going into the motor. its leaking at the plate and entrance of the plate is what it seems like.
On most engines, there are areas called "freeze plugs". They are along the base of the engine and in some cases, they are located close to the transmission and could be the cause of your antifreeze leak. Have someone get underneath the vehicle and check where the leak could be coming from. It also could be the heater hoses running to the heater core inside your vehicle. Have all the components to your cooling system checked.

You need to find the source of the leak, Follow the coolant residue to the leak. It can be tricky to find with all the plastic covers on vehicles now, You may have to remove to some covers to see the leak.
sounds like the water pump might be going out.
try letting the car cool down, open rhe radiator cap and check for flow.
If you have flow detected while engine is running put the cap back on.
Once pressure builds water will pour out even faster under the car the pump is going bad.
One good indication for a bad pump is water being thrown up against the radiator after a pressure build up.
A cooling system pressure tester can be loaned to you at a local Auto zone shop.
You use this tool in place of the radiator cap and pump up pressure in the radiator and cooling system.
Once a presure is obtsined you can check for the leak location better with the engine not running.
look in engine compartment from underneath- if water coming from directly over crank pulley(big one closest to ground) ,yes its the water pump- could also be lower hose(radiator hose closest to ground),if leaking up top - could be other radiator hose- if leaking near fire wall- heater hose- ?where is the water appearing?
Well there are only 3 things that could have gone wrong.
1. Radiator Leak - this means the radiator has developed a hole with via corrosion of the metal parts of simply integrity failure of the plastic parts of the radiator.
2. Hose leak - this could be a hole in 1 of 2 hoses that connects the engine to the radiator. Or it can also be a leak where the hose connects to the radiator (clamp Failure).
3. Water Pump breakdown - this is where the gasket in the water pump has failed and is leaking out the water rather than pumping it.
All the problems above has different ways of diagnosing. but we can probably narrow it down.
1. if the leak is near the radiator then it could be a hose connection, hose breakage or Radiator hole.
2. if the leak is nearer the engine then check the other end of the hose and if its not there then it could only be the water pump is leaking. You can check this if there are water stains on the water pump. The water pump on a 1990 corolla is mechanical turned also by a fan belt. Look for a pulley that has a hose connected to the radiator and that would be the water pump.
Let it cool down and then get a flashlight (droplight bulb will break if it gets wet) and get under there and take a good look. From what you said, sounds like you have a leak from the lower hose. Check the end connections and make sure they are tight then start it up and watch. Only other places it can leak that low there are from the pump gasket or the radiator.
If you can narrow down where the leak is coming from, it will be easier for you to fix, but it is most likely either a minor radiator leak, or your water pump. You can put a can of radiator stop leak in your vehicle, such as bars leak. It wont hurt anything. If the leak continues, and appears to be coming from the engine area, the water pump is failing, but also check around the thermostat housing, near where the upper radiator hose connects to the engine
Check the engine oil, see if the level is going up and what the condition is. you can take the oil cap off and inspect under it. if there is a milky fluid then the antifreeze is leaking in to your engine crank case which is bad for the engine bearing. The other thing to also check is the transmission fluid. make sure that its till bright red and not over filled to make sure it's not leaking in to your transmission through the transmission cooler which is apart of the radiator too. Good luck and keep me posted. Be glad to help.
