That’s the thermostat, it could be the water pump spraying into it too.

Hello star
My c220cdi2012 got warning light of collant level low 2 weeks back.lights came up only in morning for 2 datd and then disappeared.but after 2 weeks it came back yesterday and i have checked coolant is more then half or 1 inch lower then the specified mark.
my question is if i can add distilled or deionised water in it or i need to add ready mix coolant (prestone) available at tescos.
Please advice
