Could be your thermostat failing or the gasket on the thermostat. If you pull that off, boil water in a pot, once boiling place the thermostat in the water, the valve should open in 10 seconds or so, if it does not, replace it. It also could be your radiator. Let the car warm up, shut it off, feel the fins on the radiator, if you get hot and cold spots, you have a clogged/faulty radiator, replace. Thermostats are about 20-40 dollars. Radiators on ebay are about 60 for new. Those are the cheapest fixes. If it is not that, it may be your coolant temp sensor, also around 20 dollars but I believe your engine light would come on.
The noise was most likely from coolant getting on the belts and then it will burn off somewhat quick and the sound will go away.
Make sure your fans come on, if they do not come on, that is your issue.
