temperature light blinking

[TechArtBox]

can anyone give me some insight on this? my teperature light blinks red on cold starts. im assuming something is not working to blow air into the engine to help warm it up. if i restart the engine after the car has been warmed up, the blinking stops. any suggestions on what needs to be done to fix this? and what about costs?

Check the coolant level in the expansion tank when the engine is cold and make sure that it is at the max mark.

Here is the long explanation 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."

I feel like an idiot. So I filled her up and no more light. I guess after the car warms up the coolant expands and thats why when I restart, it doesn't blink anymore. Now only if I can get rid of the CEL. Thanks for the help guys.

Watch the coolant level closely if you had to fill. You may be on the way to an expansion tank failure. Check under your rear trunk carpet and make sure there's no coolant down there.

There is also an updated coolant cap as the early ones tended to leak.
