When to know if your car has an antifreeze leak?
If you’ve noticed an odd, sweet smell coming from your car after you shut the engine off you might have an antifreeze leak. Antifreeze plays a key part in keeping your engine running properly, so it’s important to know if it’s leaking.
What should coolant level be for antifreeze leak?
The coolant level should be between the “min” and “max” markings. If the tank is full, what you are smelling is probably not an antifreeze leak. If the tank’s level is below the minimum mark or it’s dry, you’ve likely got a problem and it is time to consult an expert technician.
What happens when coolant is leaking from the engine?
If an engine is low on coolant, it can run too hot, which will hurt both performance and fuel economy. Worse yet, your engine can overheat, sustaining expensive and possibly terminal damage. If your vehicle is losing coolant, you need to determine where it’s leaking from and how fast it’s leaking—and then fix it or get it fixed.
What does antifreeze do to a car in the winter?

How to check for a mystery coolant leak?
Mystery Coolant Leak 1 Get a radiator pressure tester and check that the system will hold pressure. Get some soapy water and brush on all… 2 Do a cylinder compression test. 3 Use 50/50 mix of MB fluid, sounds like you have mostly water in sys. that would drastically effect the boiling point… More
Why do I keep losing coolant in my car?

Can a overheating engine cause a coolant leak?
An overheating engine can cause more problems especially if you let it go too long and end end up cracking your block. Chances are you have either a radiator cap leak, internal coolant leak or an external coolant leak. The longer you wait the higher the coolant leak repair cost will be.
What happens when antifreeze is leaking but not overheating?
Leaking Antifreeze But Not Overheating. If you’re leaking antifreeze but not overheating or you have a car leaking antifreeze when parked, you still have a chance to repair your vehicle for a lower cost. If you continue to drive your car with low antifreeze your vehicle will eventually overheat.
Where can I find an antifreeze leak in my car?
If you don’t see any obvious signs of leakage, scan the entire engine compartment; the leak could be coming from somewhere else under the hood. If the smell is stronger inside your vehicle than outside of it, the problem could be inside the heater. Heaters utilize a small radiator-like “core” to heat the cabin air.

- Defective or deteriorated seals
- Blown head gaskets
- Improperly torqued head bolts
- Thermally warped or cracked cylinder heads
- Cracked block or cylinder head from frozen coolant
- Improperly machined head and block surfaces
- Corrosion damage of cylinder liners
- corrosion of cylinder liners
- Electrochemical erosion
- Damage or corroded cooler cores
Can a car leak if there is no coolant in the engine?
Even if you have depleted coolant levels with no sign of leakage, you could still have an internal leak that isn’t detectable from the outside of your engine. Detecting a faint, sweet smell of antifreeze with no signs of a leak is also indicative of an internal leak.
