You'll love our fast delivery, seamless shopping experience, and convenient return policy, saving you all the hassle.

The Jeep Radiator Fan Relay is a small switch that activates the cooling fan as the heat rises. You can count on Jeep vehicles to keep going no matter the road. Be it rocky trails, deserts, or winter backroads, Jeep frames are durable and the ground clearance is generous. Upon analysis, it is found that drivers prefer the open roof option, easy-to-clean cabins, and a stick-shift feel encouraging a fun over polish approach. Beginners can conveniently switch from mud to snow using the Selec-Terrain dial while axles can take a hit. The social boost offered by community events, online forums, and friendly waves from other Jeep owners is inimitable by competitors. Newer models offer touchscreen controls, voice command installation, and over-the-air fixes to maintain connection while off the grid. Regardless, all Jeep models still have the capacity to be driven through a creek at dawn. Situated between the battery and the motor of the cooling fan, the Radiator Fan Relay receives a signal from the powertrain module, then closes to supply twelve volts to the blades. When coolant exceeds the set point or AC is engaged, the fan is powered up by the Radiator Fan Relay so that more air is allowed to flush heat out of the radiator and condenser. When the temperature cools, it opens up again which helps save power, cut noise, and prolong the life of the fan. This rapid cycling prevents stationary or slowly moving traffic from heating up the engine, a simple measure that every Jeep is able to take advantage of with no need for the driver to intervene. The Radiator Fan Relay prevents a continuous draw on the electrical system, ensuring that cabin electronics stay stable during sticky summer commutes and hair-raising hill climbs, only coming into play when necessary.
