radiator cap might be leaking
antifreeze does not enter the engine at any time. locate and follow your radiator hoses and follow then and check for cracks or punctures.
look for antifreeze coming out of the radiator as the engine warms up after a cold start.
Radiator or hose but probably water pump
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.
Look at the oil on the dipstick. If you have antifreeze leaking into the crankcase the oil will be milky.
Several possibilities: 1. Radiator is leaking. 2. Coolant hose is leaking. 3. Hose clamp is loose. 3. Seal on water pump is leaking. 4. Overflow container is leaking. 5. Radiator clamp is loose or bad. Two highest possibilities: Radiator or hose is leaking.
Radiator or hoses. Possible water pump
Internal engine antifreeze leak what else could cause besides headgasket? there is no antifreeze in the oil it is clean
stuck thermostat, not enough antifreeze in radiator, leaking hose, are the usual. then it would be blown head gasket, not enough oil in engine, electric fans not coming on.
In the engine and radiatorIn the engine and radiator
No. The top hose goes to the engine. The bottom hose feeds from the engine to the heater core back to the radiator.
