What does your car radiator do? Simply put, it keeps your engine running as cool as it can. In fact, it helps keep it from overheating. How car radiators work generally, however, is more complex. Inside your Subaru, it all starts with coolant. As your engine runs and creates heat, the liquid flows through a radiator hose and back and forth between inlets and outlets. While it travels, a radiator cap compresses it. This helps the fluid take on maximum heat. After it captures all the heat, your radiator core's fins expel it, and a fan disperses it into the air nearby. The result: your engine works as well as it can, and because of that, it lasts longer. Any factory radiator can go bad, however, even one made by Subaru. When it does, it can cause all kinds of problems. For example, your HVAC system can malfunction. Plus, your engine can overheat and shut down. Luckily, spotting radiator problems is easy. Look for fin damage and sludgy coolant, listen for strange noises coming from your engine, and smell for the sweet, syrupy smell of ethylene glycol. The last indicates a coolant leak. If you think your radiator is headed toward failure, check your temperature gauge. It'll tell you if your engine's running hot. Then, do a comprehensive inspection. If the results call for replacement, avoid the aftermarket. A genuine Subaru radiator will fit your model best. Our auto parts store has plenty, and you can order one online in just a few clicks.
