Sounds like your catalytic converter is bad. If a catalytic converter is bad it can cause a rich fuel mixture that makes the exhaust smell (like a rotten eggs form the hydrogen sulfide).

first when temp cools down check coolant level, if that's ok check that fans works when you re-start engine whithin a few minutes the fan should start, if that's ok you may have a thermostat valve that's not opening
