Tired of forgetting to turn your radiator fan on to cool your ride? Is your charging system having trouble keeping up? Here is a simple way to help both those problems. The cooling fan relay kit will start and stop the fan keeping the engine at the correct temperature.

The kit includes all the electronics and connectors as well as a one inch hose adapter. Simply cut your coolant hose and connect both ends of the cut hose to the adapter. The thermal switch is installed in the adapter, so this will work on anyone’s cooling system.  Again, everything needed is included as well as detailed instructions
