Coolant G11 (Concentrate). The right anti-freeze agent makes a key contribution towards the reliable functioning of the engine cooling system under all operating and weather conditions. Cooler anti-freeze agents from Febi are precisely matched to the special requirements of the vehicle manufacturer and offer reliable protection from damages caused by freezing, corrosion, and cavitation. A good functioning cooling system is a primary prerequisite for the optimum operation of the engine. The ideal mixing ratio is 1:1, which offers frost protection to -36° C. With a ratio of 1:1 of water and concentrate, the boiling point of the cooling is approximately 107° C.+ High protection against freezing, corrosion, and cavitation Prevention of deposits and foam formation

The thermostat on your vehicle controls the flow of coolant based on temperature. When you just start your engine, the thermostat remains closed to accelerate the warm up process. After a few minutes, it opens up to allow the warm fluid to flow. If your vehicle is overheating but not blowing warm air from the heater, the problem is more than likely your thermostat.
