Hello, it sounds like a possible head gasket leak into the cooling system. What you can try is in the morning when the engine is cold, take off the radiator cap and start the vehicle. As it warms up look for bubbles coming out of the radiator cap opening. It may be different from cold to warm. So, watch it for a little while as the vehicle warms up. If there's a head gasket issue you should see bubbles from compression gases being pushed into the cooling system. There are chemical kits you can buy, but the bubble test is easy and doesn't cost anything. If it's not a head gasket issue, there may be air pockets in the cooling system them haven't been bleed out completely. Keeping the radiator cap off could help with that as well. When the thermostat opens the coolant level will drop from the radiator opening. If that doesn't give any results, then you can buy a head gasket testing kit from your local auto parts store. It's a chemical kit that will change color when there are compression gases present coming out of the radiator.
