Question about 1994 Oldsmobile Cutlass Supreme
Assuming that the computer is cutting off the engine for overheating protection (thinking that the vehicle has no coolant), there are three distinct possibilities. One is the sensor. verify it works by putting a metal strip across the two contacts on the coolant side, and see if the light goes out. The second is the wiring. Verify that all the wiring and insulation is sound, then check the connections for looseness. The third one depends on the sensor location. Sometimes there is an air bubble in the cooling system on a sensor, and that just needs to be bled out. I hope this helps you!

SOURCE: low coolant light
When that happens it is usually because the coolant level membrane sensor is faulty.
Repair is not expensive, but must be done by a qualified mechanic.

Will it stall if you keep your foot on the gas like the Idle speed is set low? Possible Idle speed motor? I'll have to look up the location of the low coolant sensor.

The problem is the coolant level sensor.What happens is that dirt buildup and sediment gets on the sensor and it is not able to detect liquid.It is located on the over flow fill tank or in the passengers side of the radiator about 4 inches down on the inside of the plastic tank.If it is on the over flow then just tap on the bottom of the tank where the sensor is located and usually the light will go off.If it is in the radiator just replace the sensor and the light will go off.Do not do this when the system is hot.Hope this helps.Good luck.
