This little guy basically does what it sounds like – it measures how much coolant is in your reservoir. It’s an electrical component, so it doesn’t actually see the coolant, it uses a float or a sensing mechanism to determine the level and then sends a signal to your car’s computer. That signal tells the computer if the coolant is at the right level, low, or sometimes even dangerously low. It's part of your engine’s cooling system. Your engine generates a lot of heat, and coolant is how it stays at a safe operating temperature. The sensor works with your dashboard gauge and often a warning light. It’s basically an early warning system; it’s letting you know if you’re losing coolant, which could lead to overheating. You'll notice if it’s failing because your temperature gauge might fluctuate or the low coolant light will stay on even after you've topped it up. It acts like a shield, preventing major engine damage from running too hot. Keeping your engine cool is critical. Overheating can cause all sorts of problems, from cracked engine blocks to blown head gaskets – really expensive repairs. The coolant level sensor isn’t the thing that cools the engine, it just alerts you to a problem before it turns into a disaster. If it fails, you might not know you’re low on coolant until you see steam coming from under the hood, and by then it's usually too late. You can find replacements for pretty much any vehicle at places like Fixparts Online. It's a relatively inexpensive part to replace, and well worth it for the peace of mind.
