If you’re experiencing blown head gasket symptoms, take action immediately. Ignoring the problem can lead to engine failure, which will cost you much more in the long run than if you’d addressed it as soon as you noticed something was wrong. By knowing the signs of a blown head gasket, you can save yourself thousands of dollars in engine repairs and make sure that your car drives reliably for years to come.
Overheating Engine
One of the most common signs of a blown head gasket is overheating. If your car starts to run hot, it must be taken to a mechanic immediately. Overheating can cause severe engine damage, so it’s best to err on the side of caution.
Low Coolant Levels Without Visible Leaks
A blown head gasket can cause your car to overheat. One way to tell if you have a blown head gasket is to check your coolant level regularly. If it’s low and you don’t notice any leaks, it could signify a blown head gasket.
Bubbles in the Radiator or Coolant Reservoir
One of the most common signs of a blown head gasket is bubbles in the coolant reservoir or radiator. When the head gasket fails, compressed air from the cylinders can enter the engine’s cooling system. This can also be the cause of coolant leaking into the combustion chamber.
White Discoloration of Oil
Another common sign of a blown head gasket is the white discoloration of your car’s oil. This is because when your head gasket blows, it allows coolant to enter the combustion chamber and mix with the oil. This can cause your oil to turn a milky white color. If you notice this, it’s essential to take your car to a mechanic right away so they can diagnose and fix the problem.
White Smoke Coming From the Tailpipe
If you notice white smoke coming from your car’s tailpipe, it’s a sign that your head gasket may be blown. The head gasket seals the engine block and cylinder head, so if it’s damaged, coolant can leak into the cylinders and cause the engine to overheat.
A blown head gasket can cause all sorts of problems and should therefore be diagnosed and repaired by a professional. Head gaskets typically last the vehicle’s life but can wear down and fail for various reasons. While replacing the gasket itself is not particularly difficult, getting to it is a labor-intensive process that will need to be handled by a professional.
