This little guy basically monitors how much coolant is in your overflow reservoir. It's a pretty simple device – it reads the fluid level and sends that information to your car’s computer. Sometimes it’s a float system, like a tiny buoy rising and falling with the coolant. Other times it uses a more sophisticated electrical resistance method. Either way, it tells your computer whether the coolant is at the right level. The computer uses that information for a few things. Most importantly, it controls the cooling fan. If the coolant is low, the computer might turn on the fan earlier or keep it running longer to prevent the engine from overheating. It also usually triggers the warning light on your dashboard – that “low coolant” light – so you know there’s a problem. It’s kind of a first line of defense against serious engine damage. Well, overheating is a big deal. It can warp your cylinder head, blow a gasket, or even seize up your engine. The coolant level sensor acts like a shield, giving you a warning before things get that bad. You’ll notice if it’s failing because that low coolant light will likely stay on even after you've topped off the fluid, or it might even flicker intermittently. Sometimes, it can cause the cooling fan to run constantly too. You can find a replacement for most vehicles at places like Fixparts Online, and honestly, it’s a relatively inexpensive part to replace considering the trouble it can save you. It’s definitely worth addressing if you’re seeing any of those symptoms. Shop with confidence: Coolant Level Sensor (MPN 32385) comes with a 3 year manufacturer guarantee!
