    I checked everything you suggested. Everything seems fine. The car is not running hot it doesn't even feel hot (my husband is not the smartest... so he checked the radiator right after letting the car run for abou 20 minutes) Any other ideas or anyway to stop the beeping?

    That still didn't stop the beeping and the light is still on. My husband unpluged the sensor to see if that was the problem but nothing happened. We are stumped, anyway to disengage the beeping that you know of?

If it was Running hot, It could be the Waterpump or the Thermostat. Take the Radiator Cap off and Start the Truck. You should see the Coolant Circulating through the Radiator, If not, The waterpump is Bad. Let Me Know! Please Rate my Solution, I need all the Help that I can Get! Thanks!

    This is Caused by a Sensor and it could be that The Sensor is Bad. There is a Cooling Sensor in your Car But, I cannot locate the Info. On where it is Located at this Time. Your Library has Haynes and Chilton Auto Repair Books on all the Makes and Models. You might try one of these Books to see if we cannot Locate this Sensor. Let me Know!

    Not that I know of. I believe that this Beep is Coming from the Computer Box and Cannot be Unplugged. Call the Local Dealership's Parts Counter and see if they know anything about stopping this Beep.

(1995 Cadillac Eldorado) - Service Engine Soon light is on.

If this problem just started I would try to get a jump on it. It will be easier to track down if the light just started coming on. Otherwise other problems may come into play and the mechanic will need longer to sort them out. At around 70.00hr.Cheapest fix is to try and drop in a set of plugs. Good luck.
