It might be just a hose ,water pump or a heater core leaking...You need to do a coolant pressure test on it and you should be able to find it....You can even rent a pressure tester from Autozone to do it.....Jim..............Here is part of a tsb about a leak also...There is also another one about the water pump leaking from the weep hole......Hope this helps....Which engine do you have?....Condition
Some customers may comment about engine coolant loss, low coolant lamp on, visible coolant, or a coolant odor from the engine compartment. Some owners may be unable to distinguish the coolant from transmission fluid due to its orange color.
Some 1996 and 1997 J and N model cars equipped with 2.4 Liter (VIN Engine Code T RPO LD9) engines may exhibit coolant leakage at the joint where the radiator outlet pipe is connected to the coolant pump cover. In addition, some of these vehicles may exhibit leakage at the joint between the cooling system air bleed pipe and the coolant outlet. On 2.2 Liter engines (VIN Engine Code 4 - RPO LN2) coolant leakage may occur between the thermostat housing and the coolant inlet pipe.
On vehicles exhibiting leakage at the thermostat gasket joint, install a new thermostat gasket with part number 24576633, using procedures outlined in the Engine Cooling Section on the Service Manual.
1. If any of the previously noted conditions occur, first inspect the vehicle per the Engine Cooling Section of the applicable Service Manual. If no other cause is found for the condition, proceed with step 2.
2. Inspect the joint between the radiator outlet pipe (thermostat housing on 2.2L engines) and the coolant pump cover (coolant inlet pipe on 2.2L engines) for signs of leakage. Pressure or dye testing may be necessary in some instances.
3. If any signs of coolant leakage are noted, replace the thermostat gasket using the procedures in the Engine Cooling Section of the Service Manual.
4. If the thermostat seal has been replaced with part number 24576633 and there continues to be leakage between the radiator outlet pipe (thermostat housing on 2.2L engines) and the coolant pump cover (coolant inlet pipe on 2.2L engines), replace the thermostat housing on 2.2L engines or the radiator outlet pipe on 2.4L engines.
