1. Low Coolant
While it seems counter intuitive, when your Impala is low on coolant may run ok with wind hitting the radiator, but when idling there’s just not enough coolant to properly cool the engine.
2. Bad Electric Fan
If the coolant level appears to be fine, then the next easiest thing to look at is the fan. Most vehicles use electric fans to cool the radiator when it gets warm enough. These fans are most important when the vehicle is idling. These fans can and do fail.
3. Bad Thermostat
Next on the list is the thermostat. Your Impala’s thermostat controls when coolant does and doesn’t enter the engine. It’ll either be on the block or water pump.
4. Bad Water Pump
The water pump in your car is turned by the Impala’s engine accessory drive system. As the engine rpm increases, so does the speed of the water pump. When the vehicle is idle, the water pump is turning slowly.
Honorable Mention: Temp Gauge
While your Impala’s temperature gauge is usually pretty reliable, it still is an electrical device that can fail. A mechanic would check the temperature of the engine manually with a heat gun in order to ensure that the gauge was reading correctly before tackling the repair.
