Mopar Thermostats & Parts

Your vehicle's thermostat plays a key role in regulating engine temperature. It ensures the engine heats up to the right level and prevents overheating. When it malfunctions, it can lead to performance issues, including engine damage. Understanding how thermostats work and why they break down can help you avoid costly repairs down the line.

What Does a Thermostat Do?

The thermostat in your vehicle monitors the temperature of the engine coolant. It opens and closes to regulate the flow of coolant between the engine and the radiator. When the engine reaches the right temperature, the thermostat opens, allowing coolant to circulate and prevent overheating. Without a properly functioning thermostat, your engine could overheat, causing major damage.

Why Do Thermostats Break Down?

Thermostats can fail over time due to wear and tear. Corrosion from prolonged exposure to coolant or debris buildup can cause the thermostat to stick or fail to open. When a thermostat gets stuck in the closed position, it can cause the engine to overheat, while an open thermostat can prevent the engine from reaching the proper operating temperature.

When Should You Replace Your Thermostat?

Replace your thermostat if your engine shows signs of overheating or if the coolant temperature gauge fluctuates abnormally. Waiting too long to replace a faulty thermostat could lead to engine damage, costing more in repairs. For replacement, choose genuine Chrysler thermostats for lasting performance. Aftermarket parts may be cheaper but are often less reliable. Vehicles like the Chrysler Journey and Chrysler Pacifica can benefit from high-quality Chrysler parts available at Mopar-Direct.

In addition to the thermostat, be sure to check your oil filter regularly. Replacing it with genuine Chrysler parts ensures that your vehicle continues to run smoothly for years to come.
