You can blow into it. that hose will only really be open to the radiator when too much pressure has built up and your radiator cap releases pressure into the overflow. All other times the tubes access to the radiator is blocked by a properly functioning radiator cap.
Remove radiator from the vehicle and have it boiled out and refurbished by a radiator shop...
Flush the coolant, change the coolant resevoir and add new coolant, it doesn't hurt to change the hoses either
Try flushing the coolant system out

Check the condenser drain line. You will find that it is stopped up and water cannot drain out. Look under the car, usually on the passenger side near the firewall. Use a blunt tool like a pencil to unclog the line. 2 In my case, the coolant overflow line was clogged. It is in manifold underneath the radiator cap, where thin tube is connected. As secondary problem to it, the coolant was leaking from the cap because of over-pressure.
I think the surgery that is done to unclog arteries is the bypass surgery.
If it is just water and not coolant, then more than likely the A/C drain line is plugged. Crawl under the car, passenger side, and find the drain line near the firewall and unclog it. If it is coolant then your heater core is leaking and needs replacing. Test the water and if it smells or taste sweet it is coolant.
