Leakage in carburator ?

Yesterday, i just take my family go to the Nusa Dua Beach, there is a private beach  -it is supposed to be public beach, but since the beach is located in the 5 star hotel complex so it become private- that we usually spend time. After finish play at the beach, on the way back to our house this sherida  -the car is namely sherida from the brand charade- is keep noisy.

I look at dashboard and the temperature meter is high, and suddenly the engine is stop. So  we pull out at the street and add the water to carburator. It took 2 big bottle of Aqua to fill up. Is it the carburator is leakage or broken? We don’t use this car in last 2 days, but suddenly the carburator is broken?

I need to service and change the oil, but since i really broke today so i will do it next following month. Hopefully nothing happen until then.
