T7Design Inline Radiator Fan Hose Adapter 45mm (1.75") M22

T7Design Inline Radiator Adapter

Our high-quality inline radiator hose adapters are available in a range of sizes from 1" (25mm) all the way up to 2" (51mm) in diameter, we make a version available to fit all common radiator hose sizes. The inline hose adapters have an M22 x 1.5 metric threaded port for a radiator fan switch. Our hose adapters are manufactured to our drawings within the UK, this ensures our products are unique to us and more importantly produced and finished to our high standards.

To determine what temperature fan switch is required you first need to work out what temperature thermostat is installed in the engine. If these components aren't matched accordingly then the cooling system cannot function at optimum efficiency. For example; if the switch temp is too low then the radiator fan will be running unnecessarily and placing unwanted extra load on the electrical system, too high and you may unintentionally be allowing the engine temperature to increase beyond its designed thermal window.

If you don't know what temperature thermostat is installed in your vehicle then you may need to physically remove and inspect the thermostat. There will be a number stamped into the thermostat mounting flange (usually in Degrees Celsius), this represents the temperature at which point the thermostat begins opening. Once you have determined this number then you can then chose a rad switch that operates at approximately 10-15°c above your thermostat temp, for example if the thermostat begins to open at 78°c then it would be best to choose a switch that turns on at 88-93°c and turns off at least 5c before the thermostat is fully closed.

ATTENTION

• Please note that the switch shown in the picture is just an illustration and the adapter does not come with a radiator switch, there are many temp switches available seperately.
• It is recommended installing the fan switch on the outlet/cold side of the engine radiator.
