Three possibilities: 1. The heater is plugged with rust. 2. The radiator cap is not maintaining adequate pressure in the system. Raising the pressure prevents boiling. Rad caps contain springs that weaken with use. 3. The coolant contains too little antifreeze (too much water) and the thermostat is stuck open. Flush the system, replace the thermostat and rad cap and refill the system with 70% propylene glycol and 30% water. (Not ethylene glycol - when it spills it poisons animals.) If the problem persists replace the heater core.

It takes more heat to boil water than to simply heat water. Unless the water is already at its boiling point.

You'd have no heat or air and radiator would boil over causing vehicle damage.

Because when the cap is removed the liquid inside wants to start cooling itself. The heat energy is released by boiling.

The material that will boil water the fastest is metal. Metal is an excellent conductor of heat and will heat the water up quickly.

Because heat changes the temperature of the water
