Here are some of the most common ways causes of a coolant leak and how to fix them.
What causes coolant to leak from the radiator?
Adding pressure further increases the boiling point, up to 267 °F (130 °C) for a 50/50 blend. A new engine is usually able to maintain its coolant in the radiator, hoses, and coolant passages. However, damage, wear, corrosion, and other problems can easily cause coolant leaks. If you suspect you may have a coolant leak, look for these symptoms.
What causes a car to lose coolant while running?
The steam disperses inside the engine compartment. With high engine temperatures, the steam evaporates or moisture collects on the engine compartment firewall and fender wells. Coolant loss results, without obvious puddles signs.
What should I do if coolant leaks in my car?
Benjamin Jerew is an ASE-certified Master Automobile Technician with over a decade of experience in auto repair, maintenance, and diagnosis. Coolant leaks are a precursor to a major engine problem, and fixing them should be high-priority. Why? Engine coolant maintains engine operating temperatures in the best range for performance and fuel economy.

What to do when your engine coolant is leaking?
Shut the engine off and let it sit about an hour so it can cool down. Then place a rag over the radiator cap and slowly turn the cap until it starts to release pressure. Wait until all the pressure has vented before turning the cap the rest of the way off. Adding Leak detection dye to the coolant can make a slow leak easier to find.
What are the symptoms of a bad coolant reservoir?
Coolant leaks. Another symptom of a potential problem with the coolant reservoir is coolant leaks. If the coolant reservoir cracks or breaks due to old age or overheating it will leak.

Where is the coolant in the radiator when there is no leak?
There’s a COLD/MIN label on the tank indicating the ideal antifreeze level when the engine is cold. The coolant in the radiator should be just below the filler neck. When you are losing coolant but no leak is visible, several parts could be the guilty party.
How much does it cost to repair a coolant leak?
Leaks are able to occur anywhere the refrigerant passes from part to another. If it isn’t a leak, the common repair can be anywhere from as little as $300 to more than $2,000. Recharging the old refrigerant is one of the most common repairs and can cost $95 to $255.
What are the dangers of a coolant leak?
As the coolant leaks and becomes low in the reservoir, the engine is no longer being cooled effectively. When this happens, the worst case scenario of a danger you may encounter is the overheating of the engine block. Not only will you be without your car, but you will have to dig into your pocket for this expensive repair.
What are common causes of coolant leaks?
Common sources of a coolant leak are: The Radiator. The radiator is pressurized, but is exposed to the stones, vibrations, shocks, and airflow that enter the front of the vehicle. Because of this, the metal on the radiator can rust or suffer metal fatigue, causing a coolant leak.
How do you repair a coolant leak?
The best way to repair a coolant leak from the engine is to use BlueDevil Pour-N-Go Head Gasket Sealer. This sealer is designed to permanently repair leaking head gaskets, freeze plugs, heat cores and all other cooling system leaks. There is no need to locate the leak first,…
What causes a leak in the coolant system?
An internal leak could be caused by a leak in the head or block or perhaps a leaky head gasket which lets the coolant escape its system. An external leak is the type of leak which is most easily diagnosed. More often than not, when you have an external leak, the coolant escapes and your car quickly overheats.
How can I tell if my coolant tank is leaking?
Identifying the Coolant Leak. There are really only three common causes for coolant leaks, although each type of leak has several possibilities, varying in severity. You may notice that coolant has collected on the ground under your car or that your reservoir tank is not as high as it should be. This could be evidence of a slow leak in your system.
