This tank basically handles the overflow from your cooling system. As your engine heats up, the coolant expands – that’s normal. Instead of just letting it spill out, this tank gives it a place to go. Then, when the engine cools down, the system can actually suck coolant back out of the tank to keep the levels right. It also helps to vent any air that gets into the system. It's part of your car’s cooling system, obviously. Think of it as a buffer. The system is sealed, and as things heat up and cool down, the volume of coolant changes. This tank accommodates that change without causing pressure problems or losing coolant. It’s usually positioned near the radiator, and has hoses running to and from it. It’s usually plastic, though some older or higher – performance vehicles might use metal. If this tank cracks or fails, you’ll likely see coolant leaking, and that can lead to overheating. Overheating can cause some serious engine damage, so it’s definitely something you want to address quickly. You’ll notice if it's failing, usually by seeing a puddle of coolant under the car, or maybe your temperature gauge will start running hotter than normal. It's a relatively inexpensive part to replace, considering the potential cost of engine repairs if you let a leak go on too long. You can find these pretty easily, we stock a lot here, and sites like Fixparts Online are good resources too if you want to check prices and availability. It’s really a key piece to keep your engine running at the right temperature. Buy risk-free: Coolant Expansion Tank (MPN 174426) is covered by a 3 year manufacturer guarantee!
