My coolant bypass hose has ripped open I replaced the hose and still overheating. My thermostat is good and coolant levels is good also. Is there anything that I could look for to fix?

Just a Guess You Got Air in the System if It was Not Overheating Before.

Turn Heater on Full Blast as Well! To Fill System.

 

I have two lights of some fluid underneath my dashboard on the firewall on the inside. No heat at all. Overheating before I changed the hose. I believe something with the heater core.

 

Not Fun!

Could be the core. These models also have hoses "down in the valley" underneath the intake manifold - hard to get at. I had a chronic overheating issue on my '06 4.6L that traced to coolant losses at that location. If you have drips inside the cabin, that does suggest the core though. Just be aware that if core replacement doesn't completely resolve it, there's another location that might be an issue - not sure if it is the same on the V6.
