HelloCustomer It sounds like your waterpump is leaking. Step one is definately curing all coolant leaks and refilling the cooling system. Once you get that taken care of, you can confirm if the cooling fans operate and that you have good cirulation. Double check that the coolant is coming from behind the pulley on the waterpump. If it's wet there, that's where to start.

I have to check if this is wright. I think the fluid is coming from another point. I was thinking heater core. I was told by my wife it started after I flushed the radiator.

The heatercore is at the firewall. If it is at the RF wheel, it is most likely the waterpump and that could leak as well after flushing the cooling system. Let me know what you find and what you need once you find it.
