GTV6 coolant loss

[gesus@domain.elided]

Hi

I seam to have a coolant loss in my '84 GTV6 and Im not absolutely 
sure where it is. 
I have seen some dripping once from the right side of the radiator 
but Im not really sure that this is the source.
>From time to time I hear a gurgling sound (I assume its from the heater)
and I have to fill up with coolant.

Is this just a leak?? Is it my radiator or my coolant overflow bottle??
Is there a block in my cooling system??

Greetings
