Billy Covington If you are considering purchasing a 2012 Subaru with manual transmission or already own one, you may be wondering if it has head gasket issues, which can be a significant problem for car owners. In this article, we will discuss what a head gasket is, how to spot signs of a faulty head gasket in your Subaru car, and how to prevent and repair head gasket issues.
What is a Head Gasket?
First, let’s understand what a head gasket is and what it does. A head gasket is a vital component of the engine and is located between the engine block and cylinder head. Its primary function is to seal the engine’s combustion chamber and prevent any leakage of gases or fluids. The head gasket also plays a crucial role in regulating the engine’s temperature by ensuring that coolant and engine oil do not mix together.
Symptoms of a Faulty Head Gasket
Knowing the signs of a faulty head gasket can save you from expensive repairs and engine damage. The following are the most common symptoms of a bad head gasket:
- Overheating engine
- Low coolant levels
- White smoke coming from the exhaust
- Sweet smell from the exhaust
- Reduced engine performance
- Milky engine oil
If you notice any of these symptoms, it’s essential to get your car checked by a professional mechanic to prevent further damage to your engine and avoid costly repairs.
Common Causes of Head Gasket Failure in 2012 Subaru Vehicles
Several factors can cause head gasket failure, including poor manufacturing, low-quality gasket materials, and poor maintenance. In 2012 Subaru cars with manual transmission, it has been observed that head gasket failures are most commonly caused by the engine’s design.
Over time, the engine block and cylinder head in 2012 Subaru cars expand and contract differently, causing the head gasket to deteriorate and leak. This issue primarily occurs in cars that have been driven for more than 100,000 miles or those that have not had routine maintenance.
