My 94 Pontiac is leaking fluid when i put water into the radiator. The hose is located in the back of the car ( under the hood) next to two fat hoses. One is rusty and the other is still black. We checked it and it has a large crack in it. What hoses is it so I can buy it and take to repair shop to fix. I'm trying to save the cost of the part and only pay labor fee. Can you help?

Is the liquid clear or colored? If it is clear and you have been using the air conditioner, it is just condensation and not a problem. If the fluid is colored yellow/green or orange and feels slippery, it is coolant. This means you may have a loose hose fitting, a leaky hose, a bad radiator cap or a bad water pump. You'll need to look under and over the engine to see where the fluid is coming from. If you added fluid recently, you may have added too much and it may be coming from the overflow tank. That tank could have a leak or a loose hose going/coming from it.
Good luck. Make sure you have plenty of antifreeze in the radiator and overflow tank at all times so you don't overheat the car. Check the levels while the car is cold.
make sure the engine is fully warmed up (check the temp gauge and feel the top hose from the radiator to the engine) that hose should be HOT and it you should NOT be able to calopse it-it should feel hard. If you do not have a leak under these conditions, you probably just have an overfull surge tank and it 'puked' out some fluid. If you top radiator hose is NOT hard after the engine is fully warmed up, you have something wrong-it could be as simple as a radiator cap that is not sealing properly, or a leaky hose, an intake manifold leak, or an internal leak in the engine (don't rule out a leaking radiator, it has end tanks that can and do leak).
SMOKE UNDER HOOD COULD BE COOLANT LEAK FROM RADIATOR ITSELF OR CHECK FOR LEAKING TOP RADIATOR HOSE AND CHECK FOR LEAKING BOTTOM RADIATOR HOSE.LOOK UNDER THE HOOD IF COOLANT BOILING OUT COOLANT OVERFLOW JUG ENGINE OVERHEATING FROM BAD THERMOSTAT OR BAD WATER PUMP.CHECK FOR COOLANT LEAK AT WATER PUMP WEEP HOLE.IF SO WATER PUMP NEED REPLACING.ADD MORE COOLANT UNTIL LEVEL CORRECT.TRY LOCATE LEAK. IF CAR OVERHEATED AND BOILED IT OUT. SMOKE UNDER THE HOOD CAN ALSO BE CAUSED BY LEAKING VALVE COVERS WHICH CAN BE FIRE HAZARD IF OIL LEAKS ON HOT EXHAUST MANIFOLD.
Sounds like a leaking heater core, must remove dash to replace and is located on the passsenger side of the dash. Before confirming it is the heater core Use a pressure tester and test radiator and all hose check for leaks under the hood first to rule out any other leaks.
first u need to pop open ur hood. take off all hoses that feed into the motor, water pump, ect. then unbolt from front of vehicle. (taking one out)
(putting one in) make sure u have all the bolts required. then bolt on, take hoses that feed into motor, water pump, ect, and make sure that the hoses are secure with a bracket. then fill with 50 50 radiator fluid.
it is the heater water supply and return, that supply water to the heater core to supply heat using hot water from the engine, the hose clamp my be loose or the hose has a hole in it you have to trace it from unner the hood fire wall to where it connects to the heater under the dash
