Coolant leak, 728i, but where from.....?

Recommended Posts

Next issue, coolant leak.

Expansion bottle, pipes all seem dry.

Noticed this when car was parked on a hill, facing downwards.

The drip was coming from below a pulley, off the belt.

Coming from stat or water pump and trickling down the belt??

Hi,

Anything above it really. I had a crack in the top hose fitting that goes on the stat.

Although if the only signs are water on the belt I'd go for the pump too...

Any play in the pump pulley with the belt off?

Cheers,

Gavin :)

Sorry fellas just wanted to update this. The leak is sorted, it was coming from the union on the pipe from the rad to the aircon compressor. A new o ring sorted it.
