Anyone ever do anything about the 2 steel tubes that run through the console area from the firewall to the heater core? Mine have a lot of surface rust and scale on them and I am concerned about them corroding through when I reconnect my heater hoses. I was thinking about capping off the ends in the engine compartment, pouring Ospho in until they were completely full inside and then draining and flushing them. Then a friend suggested using something like POR-15 and again capping off the ends and filling them completely.
Any other / better ideas?
