There may be a hole in the radiator?
You would have a leak, from either the pipes to the heater matrix (radiator), or the matrix itself.
Most Likely you have a leak from the transmission cooling tank on your radiator to the antifreeze portion of the radiator. Jeff
It sounds like a leak.
The smell of antifreeze is very strong and distinct, it does not take much of a leak to smell it. The radiator could still be full and have a small leak. I would check for antifreeze dripping onto the exhaust or on the engine block because when it is hot the smell is much more noticeable from the fumes.
there might be a leak some where in a coolant line. or maybe you have a leak in your radiator.
look for antifreeze coming out of the radiator as the engine warms up after a cold start.
Radiator or hoses. Possible water pump
Most transmissions are cooled using separate tubs in your radiator, if this tube develops a leak it could mix with your antifreeze, you need a new radiator...
Antifreeze could be running out often due to a leak. It is important to inspect the radiator for small cracks or smoke.
Sounds like a leak in the heater core.
a hose or radiator may be broken. check your hoses and radiator. where is leak coming from?? front, right?? find general area and continue from there
Either the radiator hose is loose where it connects to the radiator or there is either a small hole in the radiator or in the radiator hose. Try checking the hose to see if it's loose or check for small holes in the hose or radiator.
