Wait until the engine completely cools — at least 30 minutes. You might be able to speed up the cooling process if you can pop the hood with a latch located inside the car cabin. But, do not touch or attempt to open the hood until the engine is completely cool. Check the coolant/antifreeze reservoir.

How do you know if your Headgasket is blown?

1. White smoke coming from the tailpipe.
2. BUBBLING IN THE RADIATOR AND COOLANT RESERVOIR.
3. unexplained coolant loss with no leaks.
4. Milky white coloration in the oil.
5. Engine overheating.

How many times can an engine overheat?

Cars may be able to withstand barely overheating a few times, assuming that you stop driving every time the engine gets too hot. No car is going to overheat at a “maximum” level more than one time. Instead, if your car gets that hot, the damage has already occurred and you likely need to visit a mechanic.

Can you pour water on an overheated engine?

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.

Why is my car overheating then going back to normal?

If the thermostat fails to open the coolant does not flow to the radiator where it would under normal circumstances be cooled and drawn back into the engine to absorb more heat, get pumped back into the radiator to be cooled and drawn back into the engine again.
