Wierd sloshing noise when cold

[Joshm88]

When the car is cold and rev it to move off I can hear a strange fluid sloshing noise? Do anyone know what it might be? Can't feel anything different on the car....but it has started happening since I've been getting belt noise (also when cold)...

I haven't replaced the belts yet as they are tight and seem ok/not too worn? I would buy new ones and replace them but I've got a B-series to drop in a month or so....

The noise is confusing the hell out of me....? (

i think its the coolant running through the heater rad behind the dash? as the car heats up it expands so its compressed into the rad and finally stops!!
