btw, the heater "tap" is what it's called was a common problem for e34 models. they usually malfunction/leak. No fluid in the cabin but external? then it can only be this.
That was what I thought at first, but then I read that the heater box has drains in it? So the coolant wouldn't have made it to the interior. I guess I can order the heater valve seeing as it's only like $150 and since it's a relatively easy fix I can try that and see what happens. I just didn't see anthing more than a little bit of fluid in the area around/under the heater valve, but that doesn't mean it's not the problem. I'll try that first since I was going to replace it anyways when I did the heater core to elminate another possible breakage. After this pretty much the whole system has been done!! Good for another 5 years anyways...lol
