I have excessive coolant loss on my 85' K5 Blazer and have no idea where to look. I eliminated the easy ones like water pump and the easier ones but don't know where to continue looking

You need to pressure test the cooling system to determine where the leak is.

And if I do tht and it comes back with proper pressure tht means it is an internal leak?
