Adjustable Fan Controller
These Davies Craig adjustable fan controllers are dial-adjustable from 50°C to 100°C (122°F to 212°F) and are the perfect upgrade if you are looking to get rid of the old viscus hub fan and don’t want to drill and tap holes into your motor, these simply just slip into your radiator hose, then re-fit hose and tighten again
This adjustable fan controller is also known as a thermo fan switch allow you the freedom to set one temperature for track use or high demand situations, and then reset the temperature for highway or
day-to-day driving.
SETTING THE ADJUSTABLE THERMAL SWITCH
1. Install control knob on the shaft.2. Turn on the ignition and ensure the adjustment knob is rotated fully clockwise. The fan(s) will only run if the engine temperature is above 100°C. Note: the knob rotation is for when the switch is oriented so that the capillary tube is in a vertical position.3. Run the engine until the engine temperature is about halfway between “normal highway operating temperature” and “too hot”.
This will indicate a coolant temperature between 5°C and 10°C higher than normal.4. Immediately turn the adjustment shaft very slowly anti-clockwise, just until the fan(s) switch on, and no more.5. Allow the fan(s) to run long enough to reduce the temperature by approximately the thickness of the temperature gauge needle before the Thermal Switch turns the fan(s) off. On a cool day it should run between 30 and 60 seconds at a time, on a hot day somewhat longer. NOTE: If the fan(s) run for more than a few minutes at a time, turn the adjustment clockwise slightly to increase the cut-in temperature. The fan(s) must be set to cut-in above normal operating temperature otherwise they will run more frequently and for longer periods than necessary, and you may not achieve all the benefits of electric fan cooling.
The fan/s will operate until the coolant temperature falls by approx. 10°+ C below the Targeted/Set temperature. NOTE: Remember that coolant under pressure in a radiator boils at about 118°C.
