I replaced the radiator, thermostat and water pump. it started running hot when i am stopped at a light. after I changed the water pump I had it tested for leaks nothing found. I was told my fans are fine. what could be the issue? please help. I have to keep bleeding air out of the cooling system daily.

Welcome to 2CarPros.

You shouldn't have to always bleed air from the system unless there is a blown head gasket allowing air to enter the cooling system. Do me a favor. I am going to provide a link that explains how to check for a bad head gasket. It discusses different situations but I want you to pay close attention to step 3. Let me know what you find.

I will watch for your reply. And always, wait until the engine is cool to open the system.
