Blueish liquid beneath the car

park my forte at my brother kl house for 1 week... after leaving, my bro told me notice a blue liquid pool beneath the car... any body encounter this?? i suspect it is the coolant leakage... as before send to 10k servising, notice my collant level drop below Low level... kia lengkee service center said check pressure test etc, no leakage noticed... but i not believe... as it is very unnormal coolant drain so fast..

Observe first , coolant still drop go back C&C. Say:

"MY COOLANT IS LEAKING! "

not

"CAN CHECK IF MY COOLANT IS LEAKING? "

or .... i think ... my car is really hot....REALLY REALLY HOT......
