VW Thermostat Service Kit - Facet KIT-02070

Product Information

Thermostats are a simple device which regulates coolant flow through the engine. When cold it will stay closed, stopping coolant flow and helping the engine warm up faster. Once up to temperature, it will open and allow normal coolant flow and maintain proper engine temperature. Always install with the 'jiggle pin' bleed valve at 12 o'clock when possible.

For many applications, multiple temperature ratings are available. These ratings denote when the thermostat opens, and in extreme climates different temperature ratings can be used to assist the vehicle in maintaining proper temperatures. In very hot desert climates for instance, a lower temperature rated thermostat may be preferred.

There are two types of thermostat failures:

Thermostat stuck open (most common): Coolant will flow through the engine constantly from cold, preventing the engine from reaching operating temperature. Usually this means a rich mixture resulting in poor fuel mileage and potential catalytic converter damage.

Thermostat stuck closed: If the thermostat is stuck closed it will restrict flow into the engine resulting in an overheating condition, resulting in potential catastrophic engine damage.

About Facet

Facet began in 1946 by Francesco Andriano with the core principles of dedication, skill, courage to do, and to innovate when he opened up his laboratory. Soon after WWII, Franceso Andiano founded F.A.C.E.T with his son Mario. They began creating tungsten contacts for the telephone industry which was then a potential market with rapid growth. Due to the materials used, they were able to enter into another market, now producing plated contacts for ignition components in the Automotive Industry. In 1961 the company expanded by now producing condensers followed by caps and rotors in 1966. Since the early 90's, FACET has transformed to accommodate the arrival of electronics which as been a large part to this day. Since then, FACET has put a strong emphasis on continuous process improvements which continue to this day.
