Reply to "heater hoses"

Simply plugging the heater hoses, besides the posts on this up to now, also can trap antiifreeze in your heater core. Over a period of years, its been found that the anti-corrosion additives in the antifreeze will be used up, and you'll get some corrosion of the copper heater core. This results in a vile looking greenish-black ooze that comes out of your heater control valve, if its ever reactivated. I would suggest leaving the heater hoses completely off the heater core and doing any "plugging" at the engine. Incidently, with the system rigged as you now have, you'll have to be careful about using the defroster as its function is tied into the stock heater contol valve, too.
