Hi guys is there anyone out there who knows or has a picture of the routing of the vac. hoses coming out of the firewall that work the climate controls looks like there is one with orange stripe two with green, Mine are just hanging there want to route them right so I can have heat and airconditioning with out having to swap the vac. hose any help would be greatly appreciated,
From my '67 shop manual: Black (plain): This is your vacuum source. It goes to intake manifold vacuum, usually a small brass check valve in one of the intake runners. Orange: Recirculated air door: This one goes to the outer fitting of the round vacuum diaphragm on the blower housing. Green: Outside air door: This one goes to the center fitting of the round vacuum diaphragm on the blower housing. White: This one goes to your water valve. If you have a blue one, this was originally supposed to go to the idle advance diaphragm on the throttle linkage. It was used to speed up the idle whenever the A/C is activated. It was used only on the V-6. If you have it and don't need it, just plug it up.
Buikus Rex Thank you for your help, mine has two black lines with green stripes so I'll just have to figure witch is manifold vac. Is there anywhere you know of that you can get the vac Diaphram mine has broken ports and covered with black gasket goo, don't know if it holds vac. anymore. thanks
Hi Torque. There is two types of Auto Climate for 67. The first type are suppose to have black hoses with color stripes & type two have solid colors, so according to your description you have type I. I have the vacuum hose charts for both types and can try to scan it, if you want to. (I could not find your color combination to fit the chart). I got most of the parts for my 68 from http://www.buick-parts.com/, http://www.buickfarm.com/. (NOS), or from Mike Ordway, (used). You could also try http://www.collectorsautosupply.com/query.asp, but I find there prices to be WAY to high. Per. :beer
You can get the vacuum diaphragm new from Old Air Products: http://www.oldairproducts.com/shop/...61967&osCsid=19ce6373fd04b2ed44b5c688557c2cbd
