If it's coming from the front, there are no belts to slip,if it did, you wouldn't be running.
But sometimes a slight exhaust leak can sound very much like a chirping belt.
I would check the exhaust flanges for tightness.
You can also use a piece of rubber or plastic hose, say 1/2" diameter and put one end at your ear and use the other to probe around the motor for leaks. This hose trick works very well for leaks.
Good luck in finding your noise.
