This product combines part numbers 317-DC-0401 & 317-DC-0409 into a convenient and economical value pack and can be used with a Thermatic Electric Fans & EWP's. The mechanical switch senses the coolant temperature after it passes through the engine block prior to entering the radiator & is fitted directly into the radiator hose via the adaptor. It is adjustable from 104° to 212°F (40° to 100°C). The kit comes with everything you need for a watertight and effective installation. It even supplies rubber sleeves to enable fitment to radiator hose sizes from 1-1/4" to 1-9/16" (32mm to 40mm) diameter.

No need to squeeze the probe of the Mechanical Thermal Switch between the radiator inlet and radiator hose. This simple, economical Adaptor Kit allows easy fitting directly into the radiator hose. Just fit the probe into the compression fitting, remove about 11/16” (17mm) of radiator hose, fit the adaptor between each hose and secure the hose clamps.

*Note: If using this switch for use with your EWP's, it will not vary the speed of the pump in response to engine temperature but rather turn the pump on and off at your set temperature.
