A relay is basically an electrically operated switch. It takes a small signal from your car’s computer and uses that to control a much larger electrical current. Think of it like a gatekeeper – a small nudge opens a big door. In this case, that “big door” is the power going to your radiator fan. It either completes the circuit to turn the fan on, or breaks it to turn it off. It doesn’t make the fan run, it just allows the power to get to it. This particular relay controls your radiator fan. The fan is crucial for keeping your engine from overheating, especially when you’re stuck in traffic or on a really hot day. The engine's computer sends a signal to this relay, and the relay then tells the fan to kick on when the engine gets too warm. It's part of a closed – loop system. The engine temperature sensor tells the computer the temperature, the computer decides if the fan should run, and this relay makes it happen. If this relay fails, your radiator fan won't turn on when it's supposed to. You’ll notice if it's bad because your temperature gauge will start creeping up, especially when you're idling or moving slowly. Continuing to drive with an overheating engine can cause serious damage – blown head gaskets, warped cylinder heads, the whole nine yards. It’s a relatively inexpensive part, and replacing it can save you from a really expensive repair down the road. You can find them pretty easily; we carry a good selection at Fixparts Online, and a lot of general auto parts stores will have them in stock. It’s something you can often tackle yourself if you’re comfortable working on cars, or any decent mechanic can swap it out quickly.
