There is a warning I have learned a long time ago in highschool auto mechanics class and saw an incident later in life regarding the extreme temperatures of engine coolant. We are warned to never open or attempt to loosen the coolant radiator cap. And that probably applies to other areas of high temperature gas engine operations including oil temperatures. The car must naturally be allowed to cool before checking oil or checking other high temperature fluids including engine coolant.
I was taught a little of chemistry and learned about characters of fluids related to thermal (which is basically heat) characters of different fluids. There is a specific heat capacity related to the amount of thermal energy a fluid can store and that will determine what temperature it reaches with a given amount of thermal energy transferred into it. There is also the characteristic of thermal conductance, which is the rate at which thermal energy conductions thru the fluid and into surrounding materials. The basic laws of thermodynamics states that heat will migrate natural to colder regions, like an electrical ground. We all know that lightning conducts from the surface, which is an electric tension ground, to the clouds. It is a build up of tension and follows the path of least resistance (resistance is the act of stopping or slowing electrical energy flow). And heat energy works the same.
Long story short, I had a highschool friend that was not educated on the high temperatures and dangerous associate with allowing them to touch your skin surface. The car overheated to extreme temperature (and normal operation is already high temperature for the fluids used in the engine process to power the vehicle). He unknowingly opening the radiator fluid (which is designed as a material to only boil at a temperature that the car normally would operate within) cap. The radiator fluid had reached boiling and when he opened the cap it shot out a very high temperature wet gas which included liquids. It engulfed his arm with that material at which time he pulled away. When I looked at his arm in the middle of sort of a mental shock, his skin had slight melted which concerned me for his health. We called an ambulance and he got immediate medical attention from the aid car. They applied first aid for the "burns" on his arm which was good that they were able to get there immediately.
And I'm writing this to help people understand some of the things we shouldn't attempt to do with a gas engine car.
I'm unfamiliar with electric vehicles but would love some advice related to them as well.
