Product info

Thermostat assembly includes sensor, housing, thermostat, and gasket. Your engine coolant thermostat sits between the engine and the radiator, in a thermostat housing. The thermostat blocks the flow of coolant to the radiator until the engine has warmed up. Once the engine is warm enough, usually around 200-220 degrees F, the thermostat opens and allows the coolant to flow. The engine coolant thermostat is the most common component of the cooling system to fail, which can cause your car to overheat in the unlikely event it were to be stuck closed. More commonly, the thermostat can be stuck open, making it difficult for your engine to warm up. This can result in your car running cool, causing an overly rich fuel mixture and an inefficient running engine. It should be replaced anytime you have major work done to the coolant system.

Warranty
We offer a 2-year warranty on all parts that we sell. If the part fails within 2 years of purchase, please contact us for instructions to replace it. The warranty does not cover normal wear and tear or improper installation.

About Wahler

When it comes to automotive systems engineering, Wahler has been there nearly since the beginning, pioneering technologies that modern systems would never be able to survive without. The first patent that this German company owns is a pretty important one, and is written as the "Thermostatic Regulation of the Coolant Circuit of Internal Combustions Engines'.

You would know this as the common Thermostat, and it started a long tradition of developing and building technology to regulate the temperature of your engine, an absolutely crucial aspect that impacts both reliability and efficiency.

Since the 30s, Wahler has branched out to other regulatory components but never strayed far from its roots. Today, Wahler manufactures OEM, OES, and aftermarket components in Germany to the highest quality standards possible.

A favorite brand in the automotive service industry, when you put Wahler parts in your car, you can rest easy knowing you are installing the best quality parts available.
