The pace of automotive development has been considerable in advances in thermostat design to cater for the performance hungry vehicles currently available. Integral switches are one development, while some vehicles require thermostats for engine and EGR valve cooling and are sometimes linked into engine management systems.The highest quality materials are used in the manufacturing process, including high quality stainless steel and copper that resist the corrosive effects of engine coolant for the life of the vehicle. Further benefits include the stabilisation of pressure in the cooling system and a reduced delay in engine warm-up. All thermostats are 100% tested and calibrated, ensuring correct start-up to open temperature and maximum operating temperature. To meet the requirements of European, Japanese and Asian Pacific vehicles, thermostats can be specified with ‘jiggle valves’, while gasket sets can also be supplied if required.
