Hey, thanks in advance for reading!

Had a coolant leak coming from the radiator for a while, but the leak only seemed to happen if I didn't drive the car for a day or two. I hadn't driven the car for a week and all of the coolant had leaked from the radiator.

This morning I filled the coolant to max and drove to the shops for about 5 minutes, came home and the new coolant had leaked out too (this had never happened before).

Just to reiterate, the coolant really only leaks when I don't use the car.









The leak is visible from 3 areas underneath, the left, right and centre.

Whats the best thing to do in this situation? I've been topping the coolant up every time its low but i fear the situation may get worse.

PS: Not sure if there's supposed to be a hole in the middle of the plastic cover, I think some bugs may have gotten in.

If the radiator is leaking, replace it. Could be any one of a number of hose fittings too.

And BMW coolant is supposed to be blue, not that green. You'll need to drain, flush, and refill with proper phosphate-free stuff.

Obvious answer is obvious.
