Replace Your Ford’s Thermostat for Reliable Engine Performance

The thermostat is a small but crucial part of your engine’s cooling system. It regulates coolant flow, helping your Ford Escape or Ford Ranger maintain the right operating temperature. If it sticks open, the engine may run too cold, reducing efficiency. If it fails to open, overheating can occur, leading to serious damage.

Why Do Thermostats Fail?

Over time, thermostats can wear out due to constant exposure to extreme temperatures. Corrosion, coolant contamination, or mechanical failure can cause them to stick in one position. A faulty thermostat may trigger a check engine light, cause erratic temperature readings, or result in overheating. If left unaddressed, a bad thermostat can damage engine components.

When to Install a New Thermostat

Signs of thermostat failure include fluctuating temperatures, overheating, or a heater that doesn’t work properly. If you notice these symptoms, it’s best to replace the thermostat before more costly issues arise. A new thermostat also ensures the cooling system works efficiently with other components like the radiator. Choosing a genuine Ford thermostat guarantees proper fit and function, unlike aftermarket alternatives that may fail sooner.

We offer OEM Ford thermostats designed specifically for your Escape or Ranger. With the right replacement, you can keep your engine running at the correct temperature. Order from Ford Parts Center for dependable parts built for your vehicle.
