Can a leak in antifreeze not be detected?
Sometimes a leak may not be visible. 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.
Why is my coolant leaking in the back of my car?
You could have a leaking rubber hose or the heater control valve in the rear area. The coolant leak will need to have the cooling system pressure tested to see if a hose or component is leaking in the rear heater system. If you lose all the coolant, the engine will overheat and can cause engine damage.
Why does my air conditioner keep leaking antifreeze?
Antifreeze leaks can be caused by a variety of things but the two most common factors are age and dirty coolant. Dirt or oil in your coolant can accelerate wear in your system, leading to leaks in your water pumps, at gaskets, or at o-rings. Flushing your cooling system is the best way to stop this type of leak.

What does it mean when antifreeze goes out of an engine?
It could be a blown head gasket, a fractured cylinder head, damaged cylinder bores, or a manifold leak. It could also be a hydraulic lock.
