Hi,

I've retrofitted a type 2 airco/heater in a type 1 944. I have a question about the vacuum lines going to the airco/heater. There are 2 tubes coming into the engine bay that look like vacuum lines. Do I just hook those up? I have the schematics from the workshop manual, but those don't include the lines that go to the airco/heater.

Any help is greatly appreciated!

Regards,

One of the those tubes is the vacuum supply and the other goes to the heater valve. I'd really like to see pics of this conversion.

Hi,

They're not very sharp, but it'll have to do:

Those small tubes are hidden begind that piece of firewall that still has to be cut away:




More pics at: http://www.kogelman.nu/944.html (takes some time to load).

Which of those small tubes (not visible on the pictures) connects to what?

Thanks,

Riplin

Wow that's quite a project you got there! I can email you a diagram of hvac hoses tonight when I get home from work.

Riplin, that is an awesome project you have there. I really have to admire your ambition. I am over 50 so my memory is suspect but I think the bottom hose goes to the heater (water) valve. The top one is vacuum from the check valve/regulator near the brake booster. I chased all of this down a few years ago on my '87na looking for a "heat on all the time" problem.

The Porsche 944 parts manual has a pretty good diagram.

I just checked my car, the bottom tube does go to the hot water valve, the tube is blue/green.

Thanks!

I couldn't find that picture. Is that one from the PET cd?

Yes, that's from PET5.
