Coolant Temperature Sensor with seal and retaining spring. In modern cars, there is hardly an area that can go without electronics. The number of electronic components installed is growing steadily making cars high-tech vehicles: safer, more comfortable, and more environmentally friendly. In the electronics and sensor technology sector, febi offers a dynamically growing range of replacement parts in OE matching quality which are suitable for numerous vehicle types. Our range includes only high-quality parts, including coolant temperature sensors. They measure the temperature of the coolant. The control unit needs this value to adjust the amount of fuel to be injected to the engine temperature among other things. All coolant temperature sensors supplied by febi are intensively tested by our quality management. The quality control of electronic components is carried out with the aid of a high-resolution X-ray device. This entails non-destructive testing to determine whether the solder joints, cables, and the general processing of the circuit boards and electrical components inside the replacement part meet febi's high-quality standards. Replacement parts from febi stand for maximum performance. This is consistently ensured by the strict quality requirements for the production of every replacement part.
