What results from this defect is a cracked engine block or cylinder head failure that also causes white smoke to come from the exhaust. When the head gasket becomes damaged, coolant and oil can mix. If coolant levels are dropping, the last thing you want to hear about is a blown head gasket.

Using too much water with the coolant can lead to an increase in corrosion and rust. Radiator hoses are another component that can fail and leak.īeyond this, you may have a problem with the radiator that is causing a leak. For example, if the radiator cap gets damaged or the seal wears out, a leak can occur from this point. There are many parts of the cooling system that can fail and lead to a leak. Here are the top four reasons coolant may leak from your car. However, the degree to how bad the fault is can range from a minor issue to something catastrophic.

There are numerous issues that can lead to leaking coolant, all of which are going to be mechanical failures on some level. Of these, the water in the mixture is going to evaporate first, even if it’s just very small amounts, and it’s more likely that your car have a leak if you see a declining level. Most antifreeze mixtures are 50% coolant and 50% water. If you notice that the coolant levels have decreased slightly over time, it’s probably not the coolant that’s evaporating, but the water that’s included in the mixture. Within the closed loop construction of the cooling system, coolant is unable to evaporate. Does Coolant Evaporate?Ĭoolant doesn’t evaporate, because it sits inside a closed system. Instead of simply topping off the system, you should have it inspected to head off any potential damage. If you notice more than this when you check the levels, you are probably dealing with a leak somewhere. That equates to about two or three ounces each year. In fact, it’s normal to notice up to 0.25% less coolant after six months. If there’s nothing mechanically wrong with the cooling system, you could still notice a slight dip in coolant levels over time. Conclusion How Much Coolant Loss Is Normal?
