From a Search for the explanation....
From Loren@ rennlist -- 12 years ago!
Here is the long explaination from the service manual on the flashing coolant light.
"Four functions of the coolant warning light:
1. Engine coolant level too low -- light flashes slowly (0.5 Hz)
2. Engine compartment temperature too high -- light flashes slowly (0.5 Hz) (engine compartment blower might be faulty)
3. Engine coolant temperature too high -- light is lit; pointer on the right
4. Temperature sensor at water outlet faulty -- light flashes rapidly (1 Hz) ; pointer on the right
Note: The temperature warning in point three is indicated if the conditions "engine coolant temperature too high" and "engine coolant level too low" are present simultaneously."
If you have replaced things -- I would check that the sensor connection is secure, or maybe replace the sensor.
