Is there a diagram of all of the Vaccum hoses used in a Fuel Injected Zagato

[budzinsk]

Hi, I am replacing all of the coolant hoses and fixing the fan motor in my 82 Zagato. While I was removing the fan motor, I noticed 2 vacuum hoses that were disconnected under the dash. Is there a diagram on what hoses go where?

Thanks,
Rob

The A/C Helper card in the download section shows HVAC
hose routing. Bare in mind on some days "Guido" would
use a green hose where the yellow hose should be, or
black vs. ? etc. But the diagram will give you the routing.
You'd better have one hell of a flexible neck to get @ the
valves in the driver's footwell. Check the condition of the
vacumn hose exiting the heater valve @ the firewall too.
That's the one most likely to be bad, exhaust manifold heat.
The hoses inside: footwells, console are normally intact.

Thanks David,. That is perfect.

Glad that helped. If you are accessing the fan assembly you
obviously have the lower half of the HVAC box off already.
Go ahead & jerk off the top half to: have the fan re-done,
the heat exchanger cleaned & tested, the A/C evaporator
same/same. And, AND renew the cowl flap perimeter seals
on top of the "box". Hardware store self adhesive window
weatherproofing strips work fine. Foam strips have advanced
alot in 30 yrs. = they last longer. It's a thankless task dealing
w/those four cowl nuts/bolts on top for one person working
alone. It can be done w/bracing inside. Replacing hoses is
anyone's call while you're @ it. It's your call. Good luck . . .

Thanks David. Yes, I got the fan working again - how do you go about having it "redone"? Who does that kind of work? I am sending the heater core along with the radiator to the radiator shop tomorrow.

Thanks,

By re-done I meant either a good oil bath to ensure it'll
work a long time or if you're really lucky finding a shop
than can put in new mtr. contacts. That's all . . .

I seem to recall someone here (thinking either Allen Lofland or one of the Jims: Keller or Fierst?) retrofitted a modern 3-speed blower motor and simply skipped connecting one of the motor's speed circuits to the stock 2-speed dashboard switch.
