Thread: Heater core question

So I'm swapping out the heater core on my b14 and I can't tell if this coolant leak is coming from the valve on that upper pipe or like through the firewall or what. There's no evidence of a leak on the engine side of the firewall. I thought it was the valve at first since it was a little wet on the bottom but now I'm not so sure since it's kinda around the corner from where it looks like it's coming from here:



What do you think?

That flange is wet, I'd guess the seal between the flange and the radiator.



*On second thought it does look like its coming from that small valve thing


Either way replace! haha

That's what I'm thinking lol... just sucks because now I have to wait to find someone that has one and then shipping... this is my only car
