We have water leaking into the interior of the car with the air conditioner on. Seems like the condensation drain is plugged. where is this located on this car?

There is a drain from the condensation from the cooling coils and so this could be blocked or the hose had come off in postion when the mat or the floor was cleaned.
please check this out , clean the hose or connect the hose back to the outlet point under the dash board collection tray.

Can't find drain plug for radiator, could not locate it to drain water out after changing hose, added water temporarily to see if leak was fixed. Help, with location, don't have a manual, Thanks.

It should be on the left side (drivers side) at the very bottom of the rad saddle, pointing rearward. It may have wings on it to turn to loosen or the other style has a square in the center, which takes a quarter inch ratchet extension to turn out.

    Instuctions for removing heater core

  • Disconnect the negative cable from the Oldsmobile Alero's battery. While the car is securely raised on jack stands, drain the engine coolant into a clean container. Most models don't have a drain plug on the bottom of the radiator, so you must take off the lower radiator hose to drain the system.
  • Step 2 Remove the drain tube from the heater's housing and disconnect the heater hoses from the core. Take off the center console, if one is equipped. Then, take off the sound insulators on both sides of the car, the steering column's opening filler, the air outlet duct and the floor air outlet to reach the heater core.
  • Step 3 Disconnect the heater core cover. Remove the core-to-housing mounting clamps and remove the heater core.
  • Step 4 Install the replacement heater core. Connect the mounting clamps and replace the core cover.
  • Step 5 Replace the rear floor air outlet, air outlet duct, steering column opening filler, sound insulators and center console (if equipped). Reattach the heater hoses to the core and the drain tube to the housing.
  • Step 6 Fill the cooling system, using new coolant if the old liquid doesn't appear clean. Be sure the lower radiator hose is securely back in place before filling the radiator. Reconnect the negative battery cable.
  • Step 7 Start up the Oldsmobile Alero's engine and let it run until it reaches normal operating temperature. Observe the climate control operation and check for any leaks in the system.
