Have you ever experienced the strange occurrence of coolant coming out of your car’s radiator cap? It’s a perplexing sight, and you’re probably wondering what could be causing it. Well, fear not! In this blog post, we’ll delve into the reasons behind this phenomenon and provide some possible solutions to help you rectify the issue. Imagine your car’s cooling system as a tightly sealed container.
Just like a pressure cooker, it builds up pressure as the engine heats up. And just like how excess pressure can cause the lid of a pressure cooker to pop off, the same can happen with your radiator cap. One of the most common reasons for coolant spewing out of the cap is a faulty or worn-out cap.
Over time, the seal on the cap can deteriorate, allowing pressure to build up and escape through the cap instead of the designated overflow hose. This can result in coolant leaking out and potentially causing overheating. Another possible culprit could be a malfunctioning radiator.
If the radiator is clogged or blocked, it can prevent proper circulation of coolant. As a result, the pressure within the system increases, leading to coolant discharge from the cap. Regular maintenance and flushing of the radiator can help prevent this issue.
Moreover, a malfunctioning thermostat can also contribute to coolant discharge. The thermostat regulates the flow of coolant, opening and closing to maintain the optimum temperature. If it gets stuck in the closed position, coolant can build up pressure and escape through the cap.
Replacing the thermostat can often resolve this problem. It’s essential to address coolant leakage promptly, as it can lead to engine overheating and potential damage. If you notice coolant coming out of your radiator cap, it is advisable to have your vehicle inspected by a professional mechanic.

Excessive pressure in the cooling system
coolant coming out of the radiator cap. One of the most common reasons for coolant coming out of the radiator cap is excessive pressure in the cooling system. This can occur when the engine is overheating or there is a blockage in the system.
When the temperature inside the engine rises, the coolant expands and increases the pressure in the cooling system. If this pressure becomes too high, it can force the coolant to leak out of the radiator cap. Additionally, if there is a blockage in the system, such as a clogged radiator or a stuck thermostat, the coolant flow may be restricted, causing pressure to build up and eventually lead to coolant leakage.
In either case, it is important to address the issue promptly to prevent further damage to the engine and cooling system.
Engine overheating
Engine overheating can be a serious problem that can lead to costly repairs if not addressed promptly. One common symptom of an overheating engine is coolant coming out of the radiator cap. There are several reasons why this might occur.
One possible cause is a malfunctioning radiator cap. The radiator cap is designed to maintain the pressure in the cooling system, but if it is faulty, it can allow coolant to escape. Another potential cause is a blown head gasket.
The head gasket seals the engine block and cylinder head and if it fails, coolant can leak into the combustion chamber and be forced out of the radiator cap. Blocked radiator passages can also contribute to coolant coming out of the cap. If the passages become clogged with debris or sediment, the coolant flow is restricted and can cause pressure buildup, forcing coolant out of the cap.
Finally, a faulty thermostat can also cause coolant to overflow from the radiator cap. The thermostat regulates the flow of coolant through the engine, and if it is stuck closed, the coolant can become overheated and lead to pressure buildup. If you notice coolant coming out of the radiator cap, it is important to address the issue as soon as possible to prevent further damage to your engine.
