Whenever a vehicle loses antifreeze, also known as coolant, the usual expectation leads the owner to check for evidence of leaks at all the coolant connections and components. Obvious coolant leaks can usually be found in the form of puddles left on the pavement.
What to do if your heater is leaking antifreeze?
Heater cores are relatively fragile and it’s not unusual for them to acquire small leaks over time. To check if you have an antifreeze leak and not water, dab some up with a white cloth. If it is green, smells sweet or has a slimy feel it’s probably antifreeze.
Where are the coolant hoses located on a car?
Coolant hoses are just that: hoses. They are located at the upper and lower radiators, bypass, and heaters. Made from durable, synthetic rubber, they (at least the high-quality ones) can withstand pressure, vibration, chemicals, and heat, allowing the liquid coolant to flow freely between the engine and radiator, among others.

Why does my air conditioner hose keep leaking?
Ozone concentrations actually increase as pollution rises. When this happens, the rubber compounds are affected, and small cracks provide enough opening for particles to come in and damage the hose. Often, the cracks look like small, parallel cracks in the cover, especially at the hose bends. Choose high-quality hoses that are ozone-resistant.
So, that hose will travel from the motor back to the firewall or the rear of the engine bay. Overtime, due to heat and age, the ends of those hoses can become brittle and begin to crack where they are attached causing small leaks. In this case, the best thing to do is purchase a new hose and clamps and replace the broken hose.
