Because when the cap is removed the liquid inside wants to start cooling itself. The heat energy is released by boiling.
Water under pressure has a higher boiling point, if the water is already hot enough to boil it will suddenly erupt when the cap is removed and pressure relieved.
yes
The compound oxygen and hydrogen can combine explosively to form water.
Rubidium.
Hydrogen burns explosively. That's why Lead Acid batteries are never tested for water level with live flame.
just take the shroud off to give you a little bit of room to work leave the radiator in
There is a drain plug on the oil pan that when removed you get oil, and a radiator drain plug that when removed you get antifreeze/water. The radiator drain plug is located at the bottom of the radiator (very front of engine compartment). Typically you can find it by reaching up behind the front bumper and feeling for a large-ish wingnut. They are usually plastic, about the size of a quarter or half-dollar, and can be removed by hand.
No, it is very slow reaction.
land
if its out of the top you might need a new cap they are pressurized and sometimes the spring is bad
The radiator on a 98 Buick Century is flushed by turning the petcock to drain the coolant. Water is then flushed through the system until all contaminants are removed.
there is supposed to be water in the radiator. your radiator is supposed to be evenly mix 50/50 with radiator fluid and water, preferably distilled water.
