If your car begins to overheat when idling, but the temperature gauge moves back down once you get going, it's most likely due to a broken radiator fan. ... However, when your car is sitting still, the radiator fan should kick in, keeping the air moving over the radiator to help cool down the coolant.

Why is my car overheating when idle?
The most likely reason for this type of problem is that your fan isn't working, but the reason, and the fix, will differ depending on the car you drive. Intermittent overheating problems can also be caused by low coolant, air in the cooling system, a bad coolant temperature sensor, or even a faulty gauge.
Can low oil cause overheating?
It's usually noticed if your coolant is low, but low oil can also cause the engine to overheat. This can occur even if your coolant level is fine. If there is too little oil in the engine, it will continue to heat up because it has no opportunity to cool.
Can I drive my car after it overheats?
Driving your car when it's overheating can cause serious – and sometimes permanent – damage to your engine, so it's best to stop driving as soon as possible. Pull over and away from oncoming traffic, then turn off the engine.
Why is my car overheating when the coolant is full?
The primary cause of engine overheating is a lack of coolant. But, if your car is overheating with full coolant, it may be something more severe. Other possibilities include a faulty water pump, a radiator blockage, a stuck thermostat, or even a blown head gasket.
Why is my car overheating then going back to normal?
The most likely cause for a car to overheat and then go back to normal is a faulty thermostat that's not exchanging heat within the engine very well. Replacing the thermostat should solve this problem.
Can a bad water pump cause overheating at idle?
Bad Water Pump
Over time, the internals of the water pump can wear out, causing coolant flow to cease and allowing the engine to overheat. ... A new water pump will likely be required to keep the engine running at a safe temperature.
Why does my car say its overheating but it's not?
If you find that you've got a car running hot but not overheating there might be a few reasons: Clogged or damaged radiator. Low coolant level. Damaged water pump or thermostat.
How much does it cost to fix an overheated engine?
A badly overheated cylinder will need to be pressure tested and inspected for warping and engine block crack/melt. These issues can lead to a complete engine rebuild and cost several $1,000 to fix.
