Audi S4 Thermostat

The Audi S4 Thermostat offers accurate engine heat control to provide the driver with a reliable powerband at all times, regardless of the season. The present Audi wax-pellet core is a smooth-reacting bimetal strip (compared to previous bimetal strips), which reduces temperature variation that may rob horsepower or overstretch gaskets. This improved Thermostat would perfectly fit into various generations of S4 models, both the early twin-turbo legends and the supercharged sedans of today, since Audi did not change the screw mounting point or the philosophy of calibration. Such compatibility across models implies that owners can rely on a single known part as opposed to browsing through many confusing choices. It accelerates warm-up by opening once the coolant approaches the factory set-point, enhances fuel consumption, and, when cold in the morning, cabin heaters come on rapidly. The device will then reseal as the radiator draws the heat away, preventing unnecessary flow and ensuring the oil remains thick enough to cushion bearings during spirited acceleration. In case of a Thermostat sticking, overrunning or endless cool running may be the consequence, which makes replacement with the factory unit the guarantee that safety and mileage will be regained without any guesses. A rough composite casing helps to withstand corrosion, and an inbuilt rubber gasket is applied to avoid leaks that may expose the Audi engine to danger. The spring pressure is interchanged to accommodate the surges of the water-pump during high RPM of performance driving, a minor adjustment that contributes to stability at the load levels required during a car visit to the track on a day. All these combined offer the S4 cooling circuit race-worthy consistency coupled with daily-driving comfort, solidifying the reputation of the part as a reliable one. The Audi Thermostat is unique among the swamp of automotive component offerings in that it is supported by precise adjustment to the recommended coolant mix, making it a very simple and inexpensive powertrain health watchdog.
