No way, we said, after hearing that a radiator cap may prevent hundreds of dollars in engine damage. But we were talked into testing it and are convinced it works. All water-cooled aluminum and iron engines experience electrolysis--anywhere from 2 to 7 volts. This charge actually pulls molecules away from aluminum, eating at cylinder heads, engine covers, water pumps, radiators and heater cores. It's a leading cause of mechanical breakdowns. The solution is a magnesium anode built into the Radiator Cap. It draws current away from expensive aluminum components. The anode is sacrificed to prevent expensive repairs. (Your home water heater uses a similar anode for the same reasons.) Nothing will eliminate all electrolysis voltage in the system, but Rad Cap will add years of life to your cooling system. When the anode has been used up, about every year or two, you'll need a new Rad Cap. It's an inexpensive alternative to a new water pump or cylinder head. Start protecting your engine today with its first Rad Cap. Recommended for 924, 944, 968 and 928. Does not fit 924 Turbo. Learn More

The engine water coolant temperature sensor is a sensor that monitors the internal temperature of the engine. Coolant inside the engine block and cylinder heads absorbs heat from the cylinder heads when the engine is running. This sensor detects the change in temperature and signals the computer (PCM) so it can tell if the engine is cold, warming up at normal operating temperature or overheating. The water coolant temperature sensor is extremely important because the sensor’s input to the PCM affects the operating of the entire engine management system. Replacing this sensor would ensure an accurate temperature reading. Learn More
