Does anyone have the diagram of where the 3 heat and a/c vaccum hoses under the hood hook up and how to tell which is which,1969 Dart. TIA
Not sure what you are asking for. 3 heat and A/C vacuum? Are you talking about the 3 lines from an A/C manifold guage? Or Are you referring to where the hoses mounted in the engine compartment? Do you have original A/C or aftermarket, and 6 cyl or V-8? Joe
its v-8 factory a/c.im talking about the 3 lines coming out of firewall.I know 1 goes to intake and other 2 go to heater water valve.But im not sure which one goes to which.only marking is a red line on 1 line
Im guessing you are talking small block, with heater hose going to intake. I have a pic here of my FW stripped, but its a BB w/o AC. I'll see if I have a pic of a complete Small block with AC.
I cant find a good pic of a complete small block installed in a 69 Dart, with AC. Maybe someone here can share their's?
I would also love to have a schematic for the HVAC vacuum lines. Mine is a 1970 dart. But im sure they're the same.
yes i think they are.mine has 3 vacuum lines coming thru firewall,1 to vacuum cannister and it goes to engine and then 2 to heater water valve
Thats how my car is. The solid black hose is vacuum supply. And the black/red stripe and black/white stripe go to the valve. Currently my valve will open but it won't shut by itself. There isn't any vacuum supply to it.
I know I'm a little late to this. Maybe it can help someone else. These are for 1968 Valiant or Barracuda but they may work for Dart and possible 69s also. I added an electrical diagram also. This are form 68 service manual.
