The hearter vacuum line in our 63 Olds Dynamic 88 Holiday Coupe need to be replaced or reconnected. In the service manual we have it shows a diagram which is linear with about 6 vacuum hose hook up going to the left and right vents, the heater box vacuum diaphragm, etc. The vacuum manifold under the dash is circular and I do not have a diagram telling me which port goes to which vacuum diaphragm. Anybody have a picture or drawing showing this layout?

The car does not have AC.

Thanks for the help...

 

This is a 61-62 it may get you started, I think 63 changed? NO AC car

 

Here is a diagram of the 1963 fullsize Olds heater (without A/C).
also a drawing of the components.
The schematic shows the control as linear and the actual valve is circular . But the valve has numbers on it and they will correspond to the diagram. The hoses were marked with colored stripes, unless they have been replaced with plain black hose.

 

thanks for the help...I dug the heater control out of the car over the weekend to enable installation of the fan switch and while out I took a pic of the vacuum manifold. It is very well marked and thought it a good idea to share with everyone.

thanks,
