Are Aftermarket Engine Thermostats Good?

When it comes to replacing your car’s engine thermostat, you have a wide range of aftermarket options available. Aftermarket thermostats are both good and bad, depending on the brand and materials used in their production. Some offer great performance at a fraction of the cost, while others may compromise quality to keep prices low. Here’s what you need to know when considering an aftermarket thermostat.

The Pros and Cons of Aftermarket Thermostats

The Good:

  • Affordability: Aftermarket thermostats are often more affordable than OEM (Original Equipment Manufacturer) parts, making them a popular choice for those on a budget.

  • Variety: You have a wider range of options with aftermarket brands, which means you can find a thermostat that fits your specific needs or even upgrades your car’s performance.

The Bad:

  • Low-Quality Materials: Some cheaper aftermarket brands use low-grade materials that can compromise the longevity and performance of the thermostat. For instance:

    • Low-quality iron or steel: These materials are more prone to rust and wear, which could lead to premature failure of the thermostat.

    • Subpar PA66 (Polyamide) plastic: Some thermostats use lower-quality PA66 for the thermostat housing. Inferior plastic can warp or crack under high temperatures, causing leaks and engine issues.

    • Recycled aluminum housings: While recycling is generally good, recycled aluminum in thermostats may not provide the same durability and strength as new, high-grade aluminum, leading to reliability concerns.

Performance Risks: Using substandard materials in thermostats can lead to a variety of problems, including:

  • Erratic Temperature Control: Poor-quality thermostats may fail to regulate engine temperature effectively, leading to overheating or underheating. This can increase wear on engine components and reduce fuel efficiency.

  • Shortened Lifespan: Cheaper thermostats may need to be replaced more frequently, negating the savings you initially made by purchasing a budget part.





The Importance of Choosing a Reliable Aftermarket Brand

Not all aftermarket thermostats are created equal. The key is finding a reputable brand that uses high-quality materials and manufacturing processes. This ensures you get the benefits of affordability without compromising your car’s performance or the longevity of the part.
