Removing Coolant Cap
If your car is overheating, one of the first things you should do is remove the coolant cap. This will allow the pressure to escape and hopefully bring the temperature down. But be careful!
The coolant can be hot enough to burn you.
To remove the coolant cap, start by making sure your engine is off and cooled down. Then, locate the cap on your radiator or overflow tank.
It will likely have a picture of a radiator or water pump on it. Once you’ve found it, unscrew the cap slowly to release any pressure that may be built up inside.

The coolant reservoir is one of the most important parts of your car’s cooling system. It stores extra coolant that can be used if the engine gets too hot. If the engine starts to overheat, the coolant level in the radiator will drop and air will start to enter the system.
This can cause major damage to your engine.
driving without a coolant reservoir cap is not only illegal but also dangerous.

Conclusion
If you find yourself with a stuck coolant cap, there are a few things you can do to try and remove it. First, make sure that the cap is not hot. If it is, allow it to cool down before proceeding.
