Parts for your 2016 Subaru Exiga-Head gasket

Understanding the Head Gasket on the 2016 Subaru Exiga

The 2016 Subaru Exiga is known for its practicality and reliable performance, largely thanks to its well-engineered boxer engine. One of the critical components in this engine is the head gasket. For those who might not be familiar, the head gasket is an essential part that plays a big role under the hood.

The head gasket sits between the engine block and the cylinder head. Its main function is to seal the combustion chambers, ensuring that the pressure created by the ignition of air and fuel stays contained within the cylinders. This seal also prevents coolant and engine oil from mixing, which is vital for keeping the engine running smoothly and avoiding overheating or mechanical failure.

In the case of the 2016 Subaru Exiga, the boxer engine design means the head gasket covers a horizontally opposed cylinder layout. This setup requires a head gasket that can reliably maintain seals across multiple cylinders and support the unique stresses of the Subaru engine design.

Here's why the head gasket matters so much for Subaru Exiga owners:

• Sealing Combustion Pressure: Without a good seal, combustion pressure can escape, leading to a loss in engine power and efficiency.
• Separate Fluid Channels: The head gasket keeps the coolant and oil passages apart. If these fluids mix due to a faulty gasket, it can cause overheating or engine damage.
• Maintaining Engine Temperature: The gasket helps to prevent coolant leaks that could cause the engine to overheat and potentially warp or damage components.

Given the importance of the head gasket, it's something every 2016 Subaru Exiga driver should keep an eye on. While Subaru engines, especially the boxer style, are known for their durability, they have had known issues in some earlier models with head gasket leaks. Although by 2016 Subaru had improved their head gasket materials and designs to reduce these issues, it's still wise to understand how to maintain or check this component.

Head gasket failure can show itself in several ways:

1. Overheating: A blown head gasket can cause coolant loss, leading to the engine running hotter than normal.
2. White Smoke: If coolant leaks into the combustion chamber, white exhaust smoke might be seen.
3. Oil Contamination: Milky oil on the dipstick means coolant has mixed with oil, often due to a gasket problem.
4. Loss of Power or Misfiring: Pressure leaks can affect engine performance and cause the engine to misfire.
5. Bubbles in the Radiator or Coolant Overflow Tank: This can indicate exhaust gases are entering the cooling system through a damaged gasket.

Keeping the head gasket in good nick involves regular maintenance and paying attention to warning signs. Here are some tips for looking after your 2016 Subaru Exiga's head gasket:

• Regular Coolant and Oil Checks: Ensure the coolant level is topped up and the oil looks clean. Contaminated fluids can be early signs of gasket trouble.
• Maintain Engine Temperature: Avoid driving the vehicle if it overheats. Overheating puts a lot of stress on the gasket and can cause it to fail quicker.
• Engine Tune-ups: Keeping the engine properly tuned helps prevent pre-ignition or knocking which can increase the stress on the gasket.
• Professional Inspection: If you notice any of the symptoms mentioned, get the vehicle checked out by a mechanic ASAP. Diagnosing a gasket issue early can save on costly repairs.

When it comes to replacement, a head gasket job is one of the more labour-intensive repairs, thanks to the nature of the engine design. The mechanic will need to remove the cylinder heads to replace the gasket, which also gives a chance to inspect the heads and block for warping or other damage.

Choosing quality parts is key because a poor-quality gasket can lead to repeat issues. OEM or reputable aftermarket head gaskets made for the Subaru boxer engines are recommended. Mechanics might also recommend resurfacing the cylinder head if it shows signs of wear to ensure a perfect seal on installation.

In short, the head gasket is a small but essential component that keeps the 2016 Subaru Exiga's engine running strong and efficient. Understanding what it does and keeping tabs on your vehicle's health will go a long way in avoiding headaches down the track. Regular servicing, attentive driving habits, and proper fluids will help keep the head gasket and your Exiga in top shape for many kilometres to come.
