Good afternoon folks, first time posting, i recently(ish) got this audi a4 b8 dirty cheap obviously needing work I've done most of it but have a coolant leak and I'm assuming its this hose thats not connected and just a bolt shoved in the end. I cant for the life of me find where it goes or find a decent coolant hose diagram for the life of me. If anyone could point in the right direction of where this hose leads to that would be great, Thanks, Wyatt
