Wow, the variety of switches out there is crazy! Yes, sometimes even our old rear-wheel-drive cars need a little electrical help—in this case, in the form of a temperature switch.
Choose from a variety of thread diameters and activation temperatures to find the exact part that fits your old Opel perfectly. We offer two different thread sizes: M14x1.5 and M22x1.5. Activation temperatures range from 70°C to 100°C.
Making the right choice is easy if you know the opening temperature of your radiator thermostat—and, to be honest, that’s the only way! —Opel has always designed it (in newer vehicles) so that the activation temperature is about 7°C above the opening temperature of the thermostat insert.
