Hi all,

My C Class W205 is missing coolant, I've topped up but it's still empty, I don't see any leaks and it's causing overheating and steam

Are the holes on the side of the reservoir normal? How will it reach the guideline, sorry I'm clueless when it comes to this stuff.

This is the noise and steam coming from the Engine with the Engine off

That's a very bad coolant leak if the level goes down that quick, I'd strongly suggest finding and sorting the leak first before driving it anymore.

Yep, it literally disappears as soon as I pour the coolant in, I can't see any pooling on the ground tho.
