For instance, condensation from the air conditioning system can often be found dripping from the engine compartment and pooling on the ground and is totally benign. If you discover a pool of liquid under your car, check to verify that it is, in fact, coolant and not something else. Note: Not every puddle under your car is indicative of a coolant leak. that occur in the parts of the cooling system that are situated on the outside of the engine, such as: This is the easiest type of leak to catch before it becomes bad enough to drain your coolant down to dangerously low levels that will trigger your low coolant light to come on. Typically, you can first notice the results of these leaks in the form of coolant dripping and puddling up underneath your car, though this is not always the case. External leaks are cracks/holes/splits/etc. Types of Coolant Leaks External Coolant Leaks So, let’s move on to the types of leaks that can occur that rob your engine of its precious reserves of life-saving coolant. If that sounded tremendously expensive to you, that’s because it definitely is. When an engine overheats, it becomes increasingly susceptible to breakdown, considerable amounts of damage, and soon thereafter, catastrophic failure. With insufficient levels of coolant to regulate your engine’s temperature, it can quickly overheat.

When you consider that your engine operates by generating a rapid series of contained explosions produced by the combustion of gasoline or other liquid fuels, it’s easy to see why keeping all that heat produced by it under control is so critical, let it get out of hand. What is engine coolant? Essentially, it’s a mixture of water and chemicals that serves to regulate the engine’s operating temperature and prevent it from overheating. But first, let’s do a quick recap on what engine coolant does and why it’s so critical for your engine’s cooling system to be kept in good operating condition at all times. Below, we’ll dive further in the types coolant leaks that could be present, how you might be able to detect some leaks and list a few of the other, less likely causes of a low coolant light that don’t have to do with a coolant leak. The most likely culprit for low coolant levels is a leak somewhere in the system. So now, the more important question becomes “why is my car low on coolant?” Predictably, a low coolant light = low coolant in a vast majority of instances. If the level falls below a critical amount of coolant in the radiator or expansion tank (attached to the radiator via a hose or pipe), the sensor sends a signal to the vehicle’s onboard monitoring system which then turns on the low coolant warning light on the instrument panel in order to alert you of the issue.
Your European car has a coolant level sensor with a floating-level which rises and falls with the coolant level in your radiator. Here is what the low coolant light means on your car and the (usual) suspects behind why your low coolant light is on.Īs you have probably already guessed, the most likely reason for your Low Coolant Light to be on is…because your car is low on coolant.
