Coolant System Bleed

Sorry Mo,
Thank you for your reply. I was not very clear with what I posted. Here is what happened, I decided to change the coolant(orange) to the Peak Global Lifetime, the orange coolant has been there since I had the head gaskets changed last year. It was doing the waterfall sound right after we changed the headgasket and after repeatedly bleeding the cooling system I managed to get all the air out and it was doing okay until today when I drained and refilled the cooling system. I was doing the same procedure that I did before but the only difference is that this time I was not as successful in removing the waterfall sound in the heater lines. It was doing fine before I drained the coolant this afternoon and then the sound came back.

This is an update, I finally fixed the "waterfall sound". I purchased a warm climate(genuine part) gray thermostat, lower and upper radiator hose as a set from Rovers North which helped a lot. My upper hose was not the updated one, it still has the bleeder on the rubber hose instead of the T. It was easier to bleed the system with the new hose and I learned from here that the gray thermostat will keep the engine temps lower than the original thermostat.
