What is the Role of the Head Gasket?
The head gasket plays a huge role in your Subaru’s engine. It sits between the engine block and the cylinder head. Its main job is to keep engine oil and coolant from mixing.
This is vital for keeping pressure right during combustion, making sure your Subaru runs smoothly. A working head gasket also helps the engine stay cool.
This keeps your engine safe from getting too hot. If the head gasket fails, it can cause big problems. Your engine could get so damaged it might need to be completely rebuilt or replaced.
This could cost a lot of money. Regular checks can catch problems early, saving you money and hassle.
Knowing about your Subaru’s head gasket is key for taking good care of your car. By looking after it, you can make this part last longer. This means your car will be more reliable over time.
Common Subaru Head Gasket Issues
Subaru head gasket failure mostly comes from two types of leaks: internal and external. The Legacy and Impreza models from 1996 to 1999 often have internal leaks.
This leads to big issues like engine overheating because of coolant loss. When you see oil in the coolant overflow or high coolant temperatures, these could be signs of serious internal leaks.
Starting in 2000, models like the Forester and Outback began showing more external leaks. These don’t usually cause overheating.
Instead, they result in coolant mixing with oil, endangering the engine’s health. Subaru used composite head gaskets from 1999 to 2009, which were more likely to fail.
However, they shifted to multi-layer steel (MLS) gaskets between 2010 and 2012. This change was good for fixing external leaks, but internal failures could still happen, typically between 120,000 and 150,000 miles.
Knowing about the different types of head gasket leaks is crucial. It can help Subaru owners, both current and future, protect their cars from these issues.
The following table provides important details on common Subaru head gasket problems:
| Model Years | Head Gasket Type | Leak Type | Common Symptoms | Average Mileage at Failure |
|---|---|---|---|---|
| 1996-1999 | Composite | Internal | Overheating, oily coolant | ~150,000 miles |
| 2000-2009 | Composite | External | Coolant mixing with oil | ~150,000 miles |
| 2010-2012 | MLS | External/Internal | Coolant loss, overheating | ~120,000 to 150,000 miles |
Subaru Head Gasket Issues: Causes & Solutions
The causes of Subaru head gasket problems are linked to the materials and design choices. Switching from multi-layer to single-layer steel gaskets with a graphite coat led to more failures.
Vehicles like the Outback, Forester, and Impreza start having issues after hitting around 100,000 miles. These include leaks of coolant and oil.
Knowing these Subaru engine design flaws helps in tackling issues early. Quickly dealing with head gasket issues can avoid big repair bills.
For head gasket repair solutions, using stronger multi-layer steel gaskets is a smart move. These are better at standing up to stress and don’t fail as easily.
Keeping up with regular maintenance and checks helps catch issues before they worsen. This can keep you from spending over $2,000 on repairs.
Subaru cars made between the late 1990s and early 2000s are more likely to have these issues. About 10% of Subarus fall victim to head gasket problems.
The 2.5-liter EJ25 SOHC engine models are known for leaking oil, so they need careful watching. Signs like overheating, bubbles in radiator coolant, and coolant in the engine oil are red flags not to be ignored.
Luckily, Subaru offers special programs and extended warranties for some models to help owners with repair costs.
By using these aids and following maintenance advice, you can lessen the risk of head gasket failures.
Identifying Subaru Head Gasket Symptoms
Spotting Subaru head gasket symptoms early can prevent major engine damage and save on repair costs. This problem is common in Subaru cars, particularly in models like the Forester, Impreza, and Outback.
It usually happens after 80,000 to 100,000 miles. A key sign of failure is an overheating engine, which could mean coolant is leaking. This puts more stress on the engine.
Keep an eye out for these key signs of head gasket failure:
- White exhaust smoke from the tailpipe
- Water leaking from the tailpipe
- Milky white oil in the reservoir
- Exhaust bubbles in the coolant reservoir
- Pungent smell from the coolant reservoir
- Low coolant levels, often occurring with or without visible external leaks
- Rough idling and engine knocking
Continual overheating engine indicators signal serious problems. If you see blue exhaust smoke, it could mean different issues, including head gasket failure.
Bubbles in the radiator from exhaust gases also point to a blown head gasket. Ignoring these symptoms can worsen engine damage.
Regular check-ups, like oil changes and coolant flushes, can lower the risk of head gasket problems. Not heeding these warnings can lead to severe damage, such as cracks in the engine block. These repairs are much more expensive.
Subaru Head Gasket Replacement: What To Expect?
Replacing head gaskets in Subaru vehicles requires keen attention. The process involves taking out major engine parts, like the cylinder block. This is to get to the broken gaskets. Get ready for this work to take a good few hours.
It’s key to pick top-quality materials for the new gaskets, such as multi-layer steel ones. These are more durable and lower the chance of the same problem happening again.
Remember, the amount of labor impacts the price. It’s smart to talk with a mechanic you trust on what to anticipate. After putting in the new head gaskets, watch the coolant and oil levels closely.
This is important in the first few weeks. Seeing changes might mean there are new problems. Following these steps can help keep your Subaru running well and prevent future gasket issues.
