You might even lose a good deal of compression but that’s a topic for another time. If this is the case, coolant can leak very fast. An older car will potentially have more wear and tear on its hoses and on its engine in general. This will also depend on the age of the car. For high-displacement motors with more cylinders or those tuned for high-performance, they will definitely get hot fast. There are, however, several factors that will determine how fast your car will overheat. In most instances, your car can lose a bit of coolant before reaching unsafe operating temperatures. Why is my car losing coolant but not overheating then? If you’re seeing that it is dropping and rising, then the coolant might have reached the combustion chamber. You should also check the oil and see if you have inconsistent levels from one day to another. Blown head gasket - If it’s a blown head gasket, then one telltale sign of a coolant leak is excessive white exhaust smoke. Most head gaskets are made to last, but they can fail for a whole host of reasonsģ. If he/she finds traces of exhaust gases/residue in the coolant, then it means that the coolant has indeed managed to invade your engine internals. If you suspect that this is happening to your car, then have a mechanic analyze a sample of your car’s coolant. In some particularly bad scenarios, interior leaks can also be caused by fractured cylinder heads or a broken manifold. Sometimes, you won’t even catch the leak as the heat from the engine block can evaporate the evidence. In connection to consistent low coolant levels, this might mean that your cooling system might have sprung a leak from inside the engine. Internal damage – Some portions of your cooling system aren’t visible from the outside. Simply order the right radiator cap, and replace it.ĭo note that a problematic radiator cap can also cause your coolant reservoir to dry up.Īlways check if the radiator cap is properly closedĢ. If you continue driving with a damaged radiator cap, you’ll suffer some overheating problems eventually. The cooling system of a car needs pressure to circulate the coolant. Apart from that, sometimes a damaged radiator cap cannot hold pressure. Here are three:ġ.Worn-out radiator cap – A worn-out radiator cap allows minute amounts of coolant to escape as you are driving. So why does this happen? Losing coolant, but no leaks: Three reasons why this happensĬoolant loss with no leaks can stem from several possible reasons. Sometimes, you’ll find that you do not have coolant leaks at all, but the levels of the said fluid are always low. In some cases, though, the leak isn’t as apparent. When that happens, it might spell disaster for your car as it is crucial in staving off the accumulation of residual heat from the combustion process.Ĭoolant spills are a mess, but losing coolant without without visible leaks is a pain too This of course is especially true with coolant. Sometimes though, these fluids can escape their rightful containers. It needs oil to lubricate the engine’s moving parts, hydraulic fluid to actuate the clutch and brake, among others. It is a given that cars need several types of fluids in order to operate correctly.
