Allows the capillary sensor to be fitted in place of the standard electrical transmitter.
This thermal switch also comes with the Aluminium Radiator as there is a pre-drilled boss in it. It can also be fitted to other radiators but be prepared to remove your radiator and have a 22mm boss welded in at a radiator shop.
When fitting the Electric Water Pump this bung fills the hole where the old Water Pump fits.
Use in conjunction with Electric Water Pump Only or Electric Water Pump Conversion Kit
