ThermostatThe thermostat is a small, inexpensive, and absolutely essential part of the typical liquid cooled vehicle cooling system. Despite its somewhat humble appearance, this part of the cooling system serves to control the flow of coolant through the engine. It does this via a simple, yet ingenious design, which allows it to gauge the necessary flow by temperature. As the temperature of the engine moves toward the typical 200 degrees Fahrenheit that most passenger vehicles operate at today, the valve of the thermostat gradually opens, allowing the necessary amount of coolant to circulate through the cooling system, protecting engine parts from being damaged by the heat produced by the engine. Overheating is one of the usual signs of a thermostat malfunction, and once this happens, attention to the cooling system should be made a top priority, as repeated overheating can cause serious and expensive problems. Fortunately, replacing a failed thermostat is a fairly easy automotive project, one that can be completed with relative ease and done successfully even by those without a great deal of under the hood experience. Experienced parts sellers with a solid commitment to quality customer service, PartsGeeks.com can be trusted to get the right part delivered fast, and at a price that makes doing it yourself an attractive option.

Thermostat

You probably pay extensive attention to the internal temperature of your vehicle from day to day, but do you think a lot about the temperature levels in your engine? Maintaining consistent engine heat is essential to your vehicle’s operation, and your thermostat is the central component in ensuring that your engine remains functioning. Regular checks, assessments and repairs to your cooling system can help prevent issues on the road.

PartsGeek.com offers a wide selection of thermostat replacement parts that can help you maintain your system. Our product selection includes items from Calorstat, Gates, Stant, Kuzeh and more, and with an easy fit guide and 30-day return policy, you can find the part that truly fits your unique needs.

What Is a Thermostat?

Overall, thermostats are mechanisms that regulate the temperature of a system. In the case of your vehicle, it controls the temperature of your engine through the release of coolant. When your vehicle sits off and the engine is cooled, the mechanism remains closed. Once you start your vehicle the engine begins to heat up. After the engine reaches a determined operating temperature, the thermostat opens, allowing coolant to flow through the system, lowering the heat of the engine, allowing it to operate at the ideal temperature.

How Much Is a New Thermostat?

PartsGeek.com offers a selection of thermostats at prices ranging from $20 to $160. The cost of your replacement part depends on a variety of factors including:

  • Car make and model
  • Car year
  • Engine make
  • Thermostat Brand

Whatever your needs, the inventory offers a number of choices that fit your performance and financial needs.

How Do You Recognize a Failing Thermostat?

Failing thermostats can be one of the biggest causes for car malfunctioning, so it is important to recognize when your system begins to fail. The earlier you can detect and repair a malfunction the easier to fix the issue. Most commonly these issues arise from a system that is stuck open or shut. The first thing to look for is a temperature gauge that reads high during the first fifteen minutes of vehicle operation. Secondly, erratic changes in the temperature are a strong sign that something is wrong. Finally, leaking coolant typically indicates an issue, so be wary of any leak spots around your vehicle.

How Do You Maintain Your Thermostat?

The largest cause of thermostat malfunctioning is contaminated coolant, so it is important to regularly maintain the system and keep it clean. There are two central ways to avoid contamination, mixing coolants and excess moisture in the system. Both cause debris build up which can trap the thermostat open or closed. Regular checks of your engine can help you avoid issues.
