Mein Auto: 1997 528i BMW
Exclamation 1997 528i bmw smells like antifreeze in cabin

I have a 97 528i that was overheating while driving and would get close to the red, but then it would go back down to normal temp. It would do this often, and sometimes it got in the red so I would have to pull over. It would also smell like antifreeze at idle inside the cabin. So I took it to the shop and they said the thermostat was bad, the fan clutch was bad, and the radiator was bad. So I just changed all those and it works great now! no overheating. But it still smells like antifreeze in the cabin after the engine is warmed up at idle still. First thought was heater core, but there is no wet spots on the carpet and no fogging on the windshield when the heat is on defrost. Also no leak. So i don't know what it could be. Drives fine, just the syrup smell drives me crazy.

First, carefully look over the coolant reservoir and check for hairline cracks. Otherwise my only other guess is the heater core. Here is a link the another thread regarding the same problem. Bluebee offered lots of info in there as well

Is the smell coming from the vents or the passenger side floor. If so could be that coolant somehow found its way to the fire wall near your cabin air intake or on the filters in the cabin filter box. I dont know the best way to clean this but removing the cabin intake tubes and feeling for moisture and stickyness would be a give away
