The mechanic said it would cost about $600 to replace the heater core. I think I will tackle it on my own.

Has anyone ever done it? Is it hard?
If the heater core was leaking the interior would smell like dexcool. Does it? Replacing the heater core is a very tough job that entails pulling the dash out. There are other reasons for water in the cabin. You want to be very sure on this diagnosis.

REWARD EXCELLENCE!
