The question “Has Subaru Fixed Their Head Gasket Issue For 2019 Cars?” is a common one among potential buyers and current owners alike. Subaru’s history with head gasket problems is well-documented, leaving many concerned about the reliability of newer models. This article will dive deep into this issue, exploring the history of the problem, the changes Subaru has made, and whether 2019 models are truly free from this infamous issue.

Understanding the Subaru Head Gasket Problem

Subaru’s head gasket issues primarily affected their boxer engines, known for their horizontally opposed piston configuration. This design, while offering advantages in terms of handling and balance, presented unique challenges regarding head gasket sealing. Over time, the head gaskets could fail, leading to coolant leaks, overheating, and potentially catastrophic engine damage. This became a significant concern for many Subaru owners, impacting their trust in the brand.

Why were older Subarus prone to head gasket failure?

Several factors contributed to head gasket failures in older Subarus. One contributing factor was the material used in the head gaskets themselves. Earlier gaskets were sometimes prone to degradation and failure under high temperatures and pressures. Another aspect was the design of the cooling system, which, in some models, might not have provided optimal cooling under demanding conditions. Furthermore, the unique stresses placed on the head gaskets due to the boxer engine’s design could accelerate wear and tear.

Has Subaru Addressed the Head Gasket Issue?

Subaru has acknowledged the head gasket issue and implemented several changes over the years to improve reliability. These changes include using updated head gasket materials, revising the cooling system design, and improving manufacturing processes. The goal was to create a more robust and durable head gasket that could withstand the stresses of the boxer engine.

Improvements in Head Gasket Materials and Design

Subaru transitioned to using Multi-Layer Steel (MLS) head gaskets, which offer improved sealing and durability compared to earlier single-layer composite gaskets. The MLS design consists of multiple layers of thin steel, providing better resistance to heat and pressure. This change significantly reduced the likelihood of head gasket failure.

Enhanced Cooling System Design

Subaru also revised its cooling system designs in some models to improve heat dissipation and maintain optimal operating temperatures. This included upgrading radiators, water pumps, and thermostats to enhance cooling efficiency. These improvements helped reduce the stress on the head gaskets and further mitigate the risk of failure.

What about 2019 Subarus specifically?

By 2019, Subaru had implemented several generations of improvements to their head gaskets and cooling systems. Most reports indicate that 2019 models are significantly less prone to head gasket issues than their predecessors. However, isolated incidents can still occur, albeit much less frequently.

Maintaining Your Subaru and Preventing Head Gasket Issues

While the risk of head gasket failure is reduced in 2019 Subarus, proper maintenance is still crucial. Regular coolant changes, using the correct coolant type, and addressing any leaks promptly can help prevent future problems.

Regular maintenance is key.

“Regular maintenance is the best way to prevent head gasket issues, regardless of the model year,” says Johnathan Davis, Senior Automotive Engineer at Reliable Rides Inc. “Following the manufacturer’s recommended maintenance schedule is essential for ensuring the longevity and reliability of your Subaru.”

Conclusion

So, has Subaru fixed their head gasket issue for 2019 cars? The answer is largely yes. While no car is immune to mechanical issues, the significant improvements Subaru has made to their head gasket design and cooling systems have greatly reduced the occurrence of this problem in 2019 models. However, diligent maintenance remains essential for ensuring the long-term health of your engine.
