Hi

When I start my car (engine cold) the low coolant warning light comes on. I checked and the radiator and overflow tank are full. Also no visable leaks. Once the engine is warmed up and I turn it off and resart it, the warning light will disapear. As long as the engine is warm, I can run without the warning light. Whenever I start it cold the warning light appears until the engine is shut off again.

Any ideas?

Thanks JA
