Radiator or hoses. Possible water pump
Usually a leaking hose into or out of the water pump (depending on its location), or the water pump gasket.
Look at the oil on the dipstick. If you have antifreeze leaking into the crankcase the oil will be milky.
antifreeze leaking into the engine base. a cracked clyd. head or blown head gasket is probable cause
AnswerCheck the water pump. If the water pump bearing is worn out there will be a streak of antifreeze leaking from the bottom of the input shaft.Another prime area for coolant leaks is the intake manifold gaskets. The original gaskets fail at the front corners where the intake manifold meets the heads.
you might have a blown head gasket and the coolant is leaking into the cylender and the engine is burning it.
antifreeze does not enter the engine at any time. locate and follow your radiator hoses and follow then and check for cracks or punctures.
Possible leaking hoses or water pump
Either one of the heater hoses are leaking or you have a freeze plug on the side of the engine leaking.
it is probably your freeze plugs
look on the ground and follow it straight up to the engine
Most of the time it is because the water pump is going out and it is leaking where the pulley is on the engine.
Your car shouldn't "burn" antifreeze. If it actually is "burning" antifreeze then chances are you have a blown/leaking head gasket or possibly a cracked engine block which allows antifreeze to enter the combustion chambers. If your antifreeze is just disappearing then it is probably leaking out from somewhere. Possible leak areas to check out would be the radiator hoses, heater hoses, radiator, water pump, and the heater core. Most of the time if the heater core is leaking you'll be able to smell the antifreeze inside the car while the engine is running and the heater is on.
