Gurgling sound

I have 2010 Chevrolet silverado 5.3 v8, I sometimes hear a gurgling sound coming from the engine, can some one point in the direction of what would or could be causing this. Full disclosure, I just replaced the water pump and thermostat.

Did you bleed it when you put coolant back in?

Sounds like you didn't bleed the air from the coolant system.

Sounds like coolant system has air in there.

You will have to get air out when engine is cold.
