coolant leaking into drivers side floor

[livetheride]

I've been battling coolant leaking into the cabin for a few weeks now. it was doing it this past spring but stopped. now its getting worse. I dried my floor before a 45 minute drive last night and went out to check it this morning and there must have been at least an ounce of coolant, maybe 2, on the floor.

I used "The Right Stuff" sealant to try to seal the heatercore coolant hose gasket areas where it looks wet. This worked for a couple days, but now its leaking again.

Any ideas as to what is probably leaking? How can/should I fix it?

change the heater core or bypass it.

^^^ What he said. It could just be the heater core O rings, so look at that before yanking it out.

I have the same problem, i looped the hoses in the engine bay for now until i get time to check the core...

It could also be the solenoid valve.

I think I tracked down the main leak. seems to come from where the last gasket before the heatercore is, where the aluminum pipes hit the plastic fitting. And there is another black plastic thing, where the aluminum pipes come out of, that is leaking.
