Is my coolant tank empty?

[perspectivism]

Hi,


I just got my car back from the mechanic last week and an engine overhaul was apparently performed.

I was just checking my coolant blue bottle cap for mayo and I notice the coolant tank to be empty.

What can I top up with? Is distilled water OK?

I got this car recently and have no experiences with cars before... The min/max level outside the tank doesn't help as the window is all hazed out..

The tank looks really empty.

I wonder if the coolant is leaking?
