What is that from ? Heater Core leaking a assume ?? its progressivly gotten worse over the last 2 yrs, it was so slight at first it wasn't an issue, I live in ATL so the heater isn't on much at all ....... How big of a Fix is this going to be ? Thanks inadvance ....... Jay

if you do not need it. Just block the hoses with a blind disk which enter the heater core.
Otherwise you might have to replace the heater core or maybe just one of the connections is leaking.

highline, is the blind disk something one can buy in a hardware store or something to cut out from sheet metal? There are hose pincher but the way it flattens a hose section I am afraid it is possible to split it. I use a garden brass valve but that required two other brass adapters.Patrick C 88 750 1559K

it is just a piece of metal which fits exactly into the hose or pipe. We use these pieces often to regulate the flow of a fluid in pipes by drilling a hole in it. Small hole = low flow, bigger hole, bigger flow, no hole = blind disk = no flow.
The garden brass valve as you made it is basically for the same effect. Whatever is easiest.Shogun's E32 Tech Tips: http://tridem.han-solo.net/auto/erich/auto.htm

where are the two locations the blind discs need to go?

Could someone tell me specifically which hoses to block off.

Maybe I can use an Allen head bolt and a hose clamp to block off. Anyone happen to know the inside diameter of the tube?

Also.. I don't need a heater but will my windshield defroster still work? Guess it wont be as foggy anymore without the leak under the dash.

or maybe I can just bypass the heater core by connecting the two hoses?

This is a great post.

But I am not sure what hoses to plug. It looks like there are three going into the firewall??? I don't understand why there are three and what needs to be plugged to solve my leak problem. I'm loosing a lot of coolent and am at the point where I don't care about heat anymore.
