Help your radiator fan switch on when the cooling system calls for it with this Dorman relay: the Dorman - OE Solutions Engine Cooling Fan Motor Relay 921-300, also listed as a radiator fan relay. It fits many vehicles, among them the 2008-2019 Dodge Grand Caravan, 2008-2016 Chrysler Town & Country and 2009-2018 Dodge Journey. See the "Vehicles it fits" section for the full list.
The relay works as an electrically controlled switch that sends power to the cooling fan motor. Dorman designed it to perform like the original relay and to help maintain proper cooling system operation. Its factory-style connectors keep the swap straightforward, and the relay has been through on-vehicle testing.
- Ideal replacement: built to work like the original relay on the listed applications.
- Durable construction: made with quality materials for reliable service.
- Easy to install: factory-style connections allow a simple installation.
- Quality tested: put through on-vehicle testing to verify proper function and performance.
Signs a cooling fan relay may need replacing include a radiator fan that won't turn on, runs nonstop or works only some of the time, along with a rising engine temperature. Wiring, fuses, sensors or the fan motor itself can cause the same symptoms, so diagnose the circuit first. If a failed relay is the cause, the 921-300 replaces it.
