What causes water to leak out of the radiator?
For instance, over-filling the radiator can cause leaks from increased water pressure. A bad thermostat or a heater core can also create excessive heat and pressure on the radiator. Check the level of your radiator and the strength of your coolant while at the service station. Always check the radiator when the engine is cold; never while it’s hot.
Can a radiator leak cause an engine to overheat?

Can a worn radiator cap cause coolant to leak?
A worn, weak, or leaking radiator cap will not hold pressure, lowering the boiling point and allowing coolant to boil out. It may also allow coolant to leak externally. Luckily, this is a quick and cheap fix. Just wait for the engine to cool, refill the cooling system, and install a new radiator cap.
Can a radiator leak cause a car to overheat?
The cooling system must be in top shape to handle it. If your vehicle overheats, your engine is in trouble, and many parts of your car can be damaged including the engine, gaskets, thermostat, and other parts of the cooling system. The radiator could be damaged too. It’s important to know how to fix a radiator leak before the car overheats.
What can I do about an oil leak in my radiator?
