1998 Monte Carlo with 70,000 miles. Temperature gauge shoots all the way over to "hot" and light comes on approx. 4 minutes after starting the car. Heater blows out just cold air. There is plenty of coolant in the reservoir. Also notice a "whirr" sound coming from under the hood. Does this sound more like the thermostat, heater core? Water pump, possibly?
