Are aftermarket car thermostats good?

Aftermarket car thermostats can be a good option for many vehicle owners, as they can provide reliable temperature regulation and potentially save money compared to original equipment manufacturer (OEM) parts. However, the quality and performance of aftermarket thermostats can vary, so it's important to do research and choose a reputable brand.


What is a Car Thermostat?


A car thermostat is a critical component in a vehicle's cooling system. It is responsible for regulating the temperature of the engine by controlling the flow of coolant. When the engine is cold, the thermostat blocks the coolant from circulating, allowing the engine to reach its optimal operating temperature quickly. Once the engine is warmed up, the thermostat opens to allow the coolant to circulate and prevent the engine from overheating.


Advantages of Aftermarket Thermostats



  • Cost Savings: Aftermarket thermostats are often less expensive than OEM parts, making them an attractive option for budget-conscious car owners.

  • Availability: Aftermarket thermostats are widely available from various manufacturers, making them easier to find and replace than OEM parts, which may be more difficult to source.

  • Customization: Some aftermarket thermostats offer different temperature settings or features, allowing car owners to tailor the cooling system to their specific needs.


However, it's important to note that not all aftermarket thermostats are created equal. Some may be of lower quality or may not fit properly, which can lead to issues with engine temperature regulation and potentially cause damage to the cooling system.


Choosing a Quality Aftermarket Thermostat


When selecting an aftermarket thermostat, it's crucial to choose a reputable brand and ensure that the part is compatible with your vehicle's make, model, and year. Look for thermostats that are made from high-quality materials, such as stainless steel or brass, and have a proven track record of reliable performance.



  • Research Reviews: Check online reviews and ratings from other car owners to get a sense of the quality and performance of different aftermarket thermostat brands.

  • Consult with a Mechanic: If you're unsure about which aftermarket thermostat to choose, consider consulting with a trusted mechanic or automotive specialist for their recommendation.

  • Follow Installation Instructions: Ensure that the aftermarket thermostat is properly installed according to the manufacturer's instructions to avoid any issues with the cooling system.


By doing your research and choosing a high-quality aftermarket thermostat, you can potentially save money while maintaining the reliable temperature regulation of your vehicle's cooling system.

Do I need an OEM thermostat?


OEM thermostats are designed for a perfect fit and function for your specific vehicle model, ensuring seamless integration with your car's cooling system. Aftermarket thermostats may claim universal fitment or compatibility with a range of models, but this can sometimes lead to issues with fitment or performance.



Is it better to run a colder thermostat?


The thermostat serves to first help the engine warm up quickly (a good thing), and later regulates the coolant temperature to an optimal level. Colder isn't always better, and a well maintained cooling system always has greater capacity than it needs. That is a commonly believed myth.



Will a new thermostat stop my car from overheating?


A car's thermostat is a crucial component that regulates coolant flow, ensuring optimal engine temperatures. If you experience symptoms like coolant leaking or overheating, make sure to get your thermostat replaced as soon as possible.



What are the symptoms of a bad thermostat in a car?


Accurate Auto lists these signs below.

  • Odd Temperature Gauge Readings. Your temperature gauge should register cold when you first start your car and slowly build up to normal as the engine warms up.
  • Air Temperature Changes.
  • Coolant Leaks.
  • Strange Sounds.
  • Heater Problems.



How often should I replace the thermostat in my car?


However, they still function effectively for up to 10 years before needing a replacement. Since a problem with a car's thermostat can lead to expensive engine repairs, it is important to prolong the life of the thermostat. Here is how to do it. Monitor the coolant levels in your vehicle constantly.



Does it matter what thermostat I buy for my car?


The best temperature for a car thermostat is the one the manufacturer recommends. Why? Because the engineers of that specific vehicle designed the engine to work within a certain operating temperature, making sure the car runs as efficiently as possible while maintaining optimum reliability.



How to tell if your thermostat is bad in your vehicle?


5 Signs Your Thermostat Is Broken

  1. You Notice Erratic Temperature Changes.
  2. You Find Incorrect Readings on the Temperature Gauge.
  3. Your Vehicle Makes Concerning Noises.
  4. You Find Coolant Leaks.
  5. You Notice Problems with the Heating System.



Does changing the car thermostat make a difference?


The benefits are clear: more precise temperature regulation and improved engine performance to enhance fuel efficiency and protection against engine wear.



Is it worth upgrading thermostat?


The long-term financial benefits of replacing your thermostate with a smart thermostat extends beyond just the monthly savings. The increased efficiency and optimized performance of a smart thermostat can prolong the life of your HVAC system, saving you money on potential repairs and replacements.



How long do aftermarket thermostats last?


about 10 years
On average, most thermostats last about 10 years, depending on the model, usage, and proper maintenance. However, many people decide to replace their unit sooner to take advantage of new energy-saving technologies.
