If your car starts overheating, the key is don’t panic—but act quickly to avoid serious engine damage. Here’s exactly what to do, step by step:
If Your Car Is Overheating While Driving:
1. Turn Off the A/C, Crank the Heat
-
Sounds weird, but turning the heat to max pulls heat away from the engine.
-
It might make the cabin uncomfortable, but it can help cool the engine faster.
2. Pull Over Safely
-
If the temp gauge is spiking or you see steam, pull over ASAP.
-
Don’t wait for a total breakdown—driving while overheating can crack the engine block or warp the head.
3. Turn Off the Engine
-
Let it cool down completely—this can take 15–30 minutes.
-
Don’t open the hood right away if you see steam or hear bubbling—wait until it stops to avoid burns.
4. Check Coolant Level
-
Once it’s cool enough (wear gloves if needed), check the coolant reservoir.
-
If it’s low, add coolant or water (in an emergency).
-
Only open the radiator cap when it’s completely cool, or you risk serious burns from pressurized steam.
5. Inspect for Leaks or Damage
-
Look under the car for puddles.
-
Check hoses for cracks, bulges, or disconnections.
-
If the coolant’s full and it’s still overheating, it could be a stuck thermostat, broken fan, or water pump issue.
6. Call for Help if Needed
-
If you’re not sure what’s wrong or if the car keeps overheating, it’s best to call roadside assistance or get towed to a mechanic.

| Overheating repeatedly | Don’t drive—get it checked | Could be head gasket, pump, or more |
