Blown Head Gasket: What It Is and When to See a Mechanic
Your car’s head gasket plays a crucial role in keeping the engine running smoothly. Since it seals the space between the engine block and cylinder head, it prevents coolant and oil from mixing and keeps compression inside the engine. But when this gasket fails, it’s known as a blown head gasket—a serious issue that can cause overheating, poor performance, and costly damage. Whether you’re commuting through Harrisburg or looking to volunteer at one of your favorite charities, avoiding a blown head gasket helps you stay safely on the road.
At Meineke on Jonestown Road in Harrisburg, our ASE-certified mechanics provide inspections, repairs, and maintenance to keep your engine in top shape. So, in this post, the experts at Meineke explain what a blown head gasket is, what causes it, how to avoid it, and when to see a mechanic.
So, What Is a Blown Head Gasket?
A blown head gasket happens when the gasket cracks, leaks, or fails to seal properly. Since the head gasket must handle extreme pressure and temperature, any failure can let coolant or oil leak into the engine cylinders—or let compression escape. This causes overheating, white smoke from the exhaust, loss of power, and also coolant loss.
What Causes a Blown Head Gasket?
Several things can cause the gasket to fail, therefore Common causes include:
- Overheating – If the engine gets too hot, then it can warp the cylinder head, causing the gasket to fail.
- Old or Thin Coolant – If coolant breaks down, then it can’t protect the engine from high heat.
- High Mileage and Wear – If your car has many miles, then the gasket may weaken over time.
- Neglecting Maintenance – If you ignore coolant leaks or skip fluid changes, then you increase the risk of damage.
So, How Can You Avoid Blowing a Head Gasket?
Simple maintenance steps can help protect your engine:
- Check Coolant Levels Regularly – If levels drop often, then get your cooling system checked.
- Flush the Radiator as Recommended – Clean coolant helps prevent overheating.
- Watch for Warning Signs – If your engine runs hot or the temperature gauge climbs, then pull over and let it cool.
- Get Small Repairs Fixed Early – If you address coolant leaks or overheating early, then you can avoid major engine problems.
