What is your question?
As there is no leakage on the garage floor could this interior leak be coming through the heater?
Yes, unfortunately it is a fairly detailed repair ... Be sure the engine mounts are checked as well... Excessive engine movement can damage the new heater core and is quite possibly what caused this one to fail..
Thanks for your prompt reply! Also, the insides of the windows are greasy. This supports your answer. Is this a major repair?
