Does this mean 100% that my Heater core is dead? i do get heat, might not be 100% as it is hard to tell. Is buying a used one a bad idea?

My blower is also sporadic, but I think this is due to the water and a loose connection.

Thanks for the help

 

for the cost of a new heater core vs the time of putting one in, I'd go new. Should take you 2 hrs or so to swap out.

And yeah id say that's the heater core.

 

Done!

Thanks

 

It seems that it might only leak when it rains. I haven't seen any water in a couple of days and everything is working a-ok....

Do you think there could be water getting in somewhere from outside? i think there is rain in the forecast so I can check again.
