Can I pour water on my engine to cool it down?
Do not pour cold water into a still-hot radiator — it could cause the engine block to crack due to the sudden change in temperature. If you absolutely have to add water while the engine is still warm, pour slowly while the engine is running in neutral or park.
Will needing a oil change cause overheating?
#7 – Overheating If you don't have enough oil in your engine or if the oil hasn't been changed in a while, then it won't do as good a job of lubricating the engine's components. This will cause the engine to heat up more and eventually overheat.
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.

2004 Impala ls temperature dash gauge
fans came late on those car,like 212 and second fan comes on at 224,you reprogram it to come a lot sooner,,other thing is there might be gunk inside the block,and coolant has hard time to pass through,and staying longer than enough in block temp goes high,even tough the radiator is doing it's job,it is just coming out block lot hotter than it suppose to be,and gauge read the block not the radiator.
Heat blows only when car is in drive when coming to stop light it blows cold air. Have added more coolant but it has not fixed the problem
You problem sounds like a "Blend Door" issue, you have these doors that open & close and everything in between to adjust air temp. These doors have a "peg" that is connected to an arm or wire just like on a ten speed bike to shift gears, that peg may have broken off.
