IF YOUR GETTING A ROTTEN EGG SMELL IN THERE & HAVE A COOLING SYSTEM AND WINDING SOUND IT MAY BE A DIFFERENT ISSUE.EDUCATED GUESS?! IT COULD BE ANTIFREEZE LEEKING ONTO A BELT CAUSING A WINDING NOISE & A NASTY SMELL! LEAKING HEATER CORES SMELL LIKE ROTTEN EGGS BUT WATER PUMPS/ BAD & WET BELTS/PS PUMPS/ IDLERS/BEARINGS, ECT CAUSE WINDINGS MAY BE A COMBO OF PROBS TOO. GOOD LUCK FRANK M

A leaking head gasket. Check the coolant level and if low,, you may need to use some sealer like Blue Devil.

The high pitch squeal ia most likely the serpentine belt on the front of the engine you can buy some belt dressing from the part store and put it on there and fix that or some soap will work also, the belt may also need to be tightened. As for the egg smell if it smells like eggs it's the catylitic converter doing it's job and is normal, although you should not be able to smell it inside the car when driving you may have an exhaust leak and could be very dangerous carbon monoxide exposure.
