1) Coolant Temp is fine while driving, and sitting a stop light. When it idles for more than 5 minutes the temp rises to 3/4 and then fan kicks on and cools to 1/2. It has new water pump, new hoses and clamps.
coolant circulates fine for while, then bubbles after sitting at idle for few minutes. Then circulates fine agian.

I would check ur coolant temp sensor with a engine temp gauge moving around alot and the fan comming on alot. So both ur upper and lower hoses are hot after warm up?When the engine is cold un hook ur coolant temp sensor connector its right below ur upper hose on the head see if the connector is corroded the coolant temp sensor is under 20. Let me know what u find.
