The radiator cap will get hot if the coolant is near the cap. Caution should always be taken when removing it to avoid being burned. The maximum coolant level is below the cap, but the cap pressurizes the system. Removing it too quickly without allowing the pressure out can result in serious injury.

Never open the radiator cap when the engine is hot?
A radiator cap can not only be hot, but it is holding in pressure. When the cap comes off under pressure, hot antifreeze will spray out, possibly causing injury.
Where do you put stop leak in radiator if there is no radiator cap?
On most cars if they don't have a radiator cap, then you can put it in the cooling system by pouring it in through the upper radiator hose. Even if you are suppose to do this while engine is hot DO NOT because it will have the same affect as pulling the radiator cap while hot.
Where is the radiator cap on a 1999 Volvo S80 Turbo?
There is a white tank up by the passenger's side fender. This is the reservoir for the radiator. Do not remove the cap while the coolant is hot. The radiator itself does not have a cap on it.
Why is the radiator cap not getting hot?
The radiator cap may not be getting hot because it is located in a separate reservoir from the radiator itself. It is designed to maintain pressure within the cooling system and does not directly contact the hot engine coolant.
Why does the coolant boil in the surge tank but the temp gauge don't go to hot on a 1994 Chevy Caprice?
It could be that the radiator cap is not able to maintain pressure. Check the radiator cap for cracks or any other damage. Replace if necessary. DO NOT remove the radiator cap when the engine is hot.
Why is dangerous to remove the radiator cap of a car when the engine is still hot?
Hot water in the radiator is under pressure and can burn you.
Do you check radiator fluid when car hot or cold?
Do it when the car is cold if the radiator is hot fluid may be forced out when you take off the cap.
Why would antifreeze leak from the radiator cap?
If you have a "Leak" from the cap either the cap needs to be replaced or the top of the Radiator is damaged. It is normal for thermal expansion (water gets bigger when hot) to cause the coolant to go into the expansion tank when cars is hot and to be drawn back into the radiator as the engine cools
If a car is overheating will radiator cap be hot?
most likely it will be hot so put snow on it
How do you add antifreeze to scion Tc?
Remove the radiator cap when the engine is cool and add the coolant into the radiator or you can add to the coolant overflow bottle. DON'T remove the radiator cap when the engine is hot!!!
Where is the radiator cap located on a 2000 Ford Focus?
If the cap on the Resoivoir twist or turns on says DO NOT OPEN HOT and there is no cap on rad then this is where you fill it at.
How does an automotive radiator reservoir work?
A hot radiator releases excess coolant through the spring-loaded cap in to the reservoir, and when cooled the partial vacuum created by cooled radiator pulls it back in. A reservoir should be only about 1/4 full cold on a system that uses a radiator cap, some cars have a pressurized cap on reservoir and no cap on radiator
