warning alert water lamp?

friends peugeot old models I use 306 my sedan car was warning, it looks like faucet isarit, it was already in orange color, it was time to check the oil, but when we go with the tastes, we will make maintenance, we took it to the first industry, they boiled the hot water, cleaned the area with whip, they did not give a warning. I didn't think there was a complete solution from my head.

coolant decreased, check for possible leaks. Also, please introduce yourself to other members in accordance with the format in the meeting topic section. Thanks.

Thanks for the answer, my teacher, I have not used a car for 2 days.

Add water to the reduced water reservoir in the radiator until it reaches max. Be sure to check it occasionally. otherwise you will take the engine
