What happens when you open radiator cap while hot?
You should never open the radiator cap while the engine and coolant are hot. Opening the radiator cap while the coolant is that hot can cause the boiling coolant to surge out of the radiator and cause third degree burns on any skin it gets on – yours. So, wait for the coolant to cool before opening the radiator cap.
Can a bad radiator cap cause an engine to overheat?
Another possibility: Pockets of air in your cooling system can prevent coolant circulation and lead to overheating. This air can enter the cooling system through a radiator cap with a bad seal. To avoid serious engine damage, you must shut off your engine immediately at the first sign of overheating.
When to take the cap off the radiator?

Your radiator hose collapses: If you open your hood and notice that your radiator hose has collapsed from internal suction, this can be a symptom of a bad radiator cap. Your cap is likely not letting coolant from the expansion tank be drawn back into the cooling system as it cools down.
