Wow, there are switches for everything, it's 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.
Free choice of thread diameter and switch temperature to find exactly the part that fits your old Opel perfectly. We offer two different threads, namely M14x1.5 and M22x1.5. In addition, switch-on temperatures from 70°C to 100°C.
The right choice is easy if you know the opening temperature of your radiator thermostat, and to be honest, only then! - Opel has always kept it this way (in newer vehicles), with the switch-on temperature being about 7°C above the opening temperature of the thermostat insert.
