Jeep Genuine Mopar Thermostats

Refine Results

A car thermostat is an essential component of the cooling system of any vehicle. This small device sits between the radiator and the engine of a liquid-cooled car and regulates the flow of the engine coolant to the radiator. JeepsAreUs offers great deals on car thermostat replacements for various Jeep models.

Maintain Optimal Temperatures Using Car Thermostats

Jeep engines are subject to excessive amounts of work and need to be kept at safe temperatures in order to function properly. Car thermostats regulate these engine temperatures and ensure the engine works efficiently while keeping it from overheating. This component controls the flow of coolant into the car engine, depending on its current temperature.

Erratic changes in engine temperatures are one of the symptoms of a faulty or broken car thermostat. Engines with higher temperatures than normal operating temperatures lead to poor engine performance as they wear down quicker as well as cause constant engine overheating. If you need replacement thermostats for your Jeep, we have you covered with 100% genuine parts.

Purchase OEM Jeep Thermostats at Great Prices

When your engine starts to overheat frequently or begins to perform poorly, its thermostat is most likely damaged and needs to be replaced. JeepsAreUs is the country’s leading Jeeps parts retailer with over 25 years of service. We have premium thermostats for different models and model years of Jeep vehicles.

Frequently Asked Questions: Thermostats

Which way does a thermostat go in a car?

Car thermostats have short and long ends. The shorter tip faces your radiator hose and points away from your engine. On the other hand, the long end of the car thermostat should be directed towards or inside your engine.

How does a car thermostat work?

As your engine warms up, the bypass valve of your car thermostat stays open so the coolant flows within your engine. The coolant will then heat up and go to a wax-filled cylinder. Once the hot coolant flows to the cylinder, the wax will melt and expand to open the main thermostat valve. The opening will then lead the coolant from the engine into the radiator and close once the coolant is cold enough.

How long does a car thermostat last?

Most auto thermostats will run up to ten years before you need to replace them. However, the lifespan of some thermostats can vary across vehicles. You might need to replace them more frequently if your car starts to overheat or have coolant leaks constantly.

When should I replace the thermostat in my car?

Signs of a faulty thermostat include the following:

  • An illuminated check engine light

  • A faulty heater and cold engine

  • An overheating engine

  • Higher temperature readings from your temperature gauge

  • Varying air temperatures

  • Coolant leaks

  • Unusual noises

If you encounter any of these problems, it’s best to have your car thermostat replaced right away to avoid further engine complications.

How do I test my car’s thermostat?

Testing your vehicle thermostat can be done by following these simple steps:

  1. Open the hood of your car after letting your engine cool to find your thermostat.

  2. Once you’ve located the thermostat, remove the radiator cap to make sure that the coolant is flowing. If the coolant is circulating, you have an open thermostat valve.

  3. If the coolant doesn’t flow, let your vehicle reach optimal temperature and look at your radiator filler neck. Limited coolant flow means a closed temperature valve.
