Hello all,

new owner of a 07 328xi. I have a coolant leak at the upper radiator hose, just under the airbox. I identified this leak while taking apart the system, as I thought it was a mickey mouse flange leak which seems very common on this engine. The gaskets were really hard, but with lack of parts and the need to drive, I just put everything back with just a clean. Lucky me, the leak was mitigated, but recently came back (probably because of the cold here).

The hose itself (part 17127531579) does not leak, would anyone have the part number of just the gaskets (or event a link to napa canada) so that I can order the correct parts ? I was not able to find accurately the correct part.

Thank you all !

Check with FCPEuro for the correct part number.

Both helpful tips, but I think the problem is that the gaskets are not available separately.

I would (and have) just replace the hose. Even if it's not leaking, they don't last forever.

The Cooling system is the E90's biggest shortcoming. From the water pump to the mickey mouse flange to the hoses. I've had to replace it all from radiator to almost every hose.

Just replace the hose. It's not a matter of "IF" but "when" on these cars

jiigrec when you say gasket, do you mean the O-ring? Those can be replaced. You can purchase an entire set: https://www.amazon.com/gp/product/B07N6QV3N4/
But any doubt, replace the hose itself.
