Hi Guys,

I have a 1995 Caravelle 2.5 ACU which has a broken heater core. Was driving with the kids and had the A/C running when a burst of steam started rushing through the vents and smell of coolant...a bit of a scare! Anyway, I have taken out the dashboard and got to the offending unit. I have also noticed that the previous owner must have removed this unit before as it has most of the vacuum pipes unplugged and blocked with screws . Kinda explains why I could never get the lower vents to work or to make some adjustments. Also on acceleration, I would hear one of the vents open up - vacuum leak? The foaming material on the vents is completely gone. So I guess my questions are:
- Does anyone know where I can get hold of a vacuum pipe diagram for this system so that I can attempt to reconnect the vacuum hoses correctly?
- Where can I get a replacement heater core? I'm in Victoria but an overseas supplier would be alright if I cannot get one closer to home.
- What else can I use on the flaps instead of the foaming material?

Cheers!
Steve
