Coolant in cabin

[James_M20]

About a week ago I noticed my drivers side carpet was soaking wet, I discovered the substance was coolant. I began cleaning up the coolant thinking that no more can leak into the cabin because nothing was being pushed through the heater core. A day later I came out and there was just as much coolant soaked into the carpet. This time I disconnect the feeder and return hose to the heater core on the firewall in the engine bay. A day later there was just as much coolant on the floor. My coolant reservoir is also empty now but there is still coolant throughout the pipes (when I put pressure on them I hear coolant flow). What the hell is going on. I'm replacing the heater core for sure where do I get one that will be a direct fit I've been hearing there's a lot of issues with o-rings, I have a 1990 325i

Might not be the heater core, but the heater control valve. I'd check it out before ordering to possibly save yourself some money. I just went through this myself recently.

Like the others have said, Steve at Bluntech will help you out right away.

Yeah get a pressure tester and see where it leaks from. Those heater control valves can go bad and cause a messy drivers side
