Anyone got a clue why i have water pouring from this hole?

I just changed the radiator and thermostat on my 2001 330ci and no i have coolant leaking from this hole at the bottom of the bracket thing that mounts to the rad with two torx screws. Any ideas? Its really annoying me

try this,
Put car up on jack stands, chock the wheels. get up under front with lower splash tray removed.
have someone start it and wait for it to warm up. The expansion tank is known to leak at the seams once tstat opens up.
That was only way I found my leak.

I'm going to guess that you have a manual car but maybe got a radiator for the automatic...maybe vice versa.

Double check the PN you should have; confirm with supplier that they sent you correct radiator. If OE radiator, you just need to install a different leveling plug I believe. Hope it's that easy for you.

I've seen the same post as yours before a few times. It won't be an easy search, I'm afraid. Try 'radiator' 'leveling plug' see if that helps. Maybe "leaking radiator'?

GL, OP...hth

This was the exact problem. I came to this conclusion after noticing that most other rads for sale have a choice of drain plug housings.
The difference between the two is that the automatic cars have a 70mm long housing that isn't hollow. The manual cars have a 50mm one.

Anyway it's sorted now after much moneys and petrol. A very difficult answer to find on any forum. I ended up being given the OE part for no extra cost and a gallon of coolant too.

I hope this post comes in handy for someone else one day. Ball ache.

Difficult answer? I found it reading one of only about 10,000 cooling threads...I'm glad I remembered it. My radiator didn't come with a bleed screw, so maybe that's why I was searching around for that info.

Hope you read 10,000 threads on bleeding!
