What causes a radiator to have over boiling point?
What you are describing is usually caused by a weak radiator cap. Weak meaning it is no longer holding the pressure which is needed inside the system. Since you said you just replaced the cap, having just water in the system will lower the boiling point and may cause over pressure in the system.
Why do I have hot water coming out of my radiator?
If you’re seeing gas bubbles or some boiling in the liquid when you remove the radiator cap, a cracked head or block may be to blame. Do not remove a radiator cap from a hot engine to check. You can experience a shot of boiling water exploding under pressure. Your local repair shop can perform test to identify cylinder head or engine block cracks.
What causes coolant to overflow from the radiator?
Your problem may simply be a loose or damaged cap not keeping coolant where it needs to be. The radiator cap is designed to allow access to fluids in a ‘closed’ system. The coolant used to cool the engine does so at maximum efficiency when kept at specific pressure. Check your owner’s manual for proper cap replacement.
How does the water pump in a radiator work?
The water pump circulates coolant through the cooling tubes of the radiator, where it cools and travels through the engine passages and hoses. Coolant, or antifreeze, is designed to flow smoothly through all of the cooling passages, with no air blockages.

Why is my coolant boiling out of my overflow tank?
This is most likely the result of a failing fan switch relay or a failed thermostat. The thermostat is a component that regulates the flow of coolant through the motor based upon specific temperatures. When the engine reaches a certain temperature, it opens allowing coolant to flow through the radiator and then to the motor.

What does it mean when coolant bubbles in radiator?
Coolant, or antifreeze, is designed to flow smoothly through all of the cooling passages, with no air blockages. A thermostat opens and closes to regulate the coolant flow for engine warm-up and circulation. Air bubbles in the coolant, at the radiator or expansion reservoir, means air has entered the system at some point.
