So I was working on the car yesterday, changing the battery cables and such, and I notice a hose with a screw in the end of it. Not sure what the heck that is, but I took pictures.........
Dreaded vacuum hoses.. I despise them. There are diagrams for them, but I have had no luck trying to use them as my cars were tampered with before I got them.
Looking at your other thread with pictures, it looks like your car may be a 72, and not a 73??? What engine and transmission do you have? These options will affect what vacuum diagram applies to your car. It's easier and helpful to include engine and trans, etc in your signature. A member on here (rthomas771) has a very good website which includes vacuum diagrams. Like blugene said, there is lots of help here, just ask!! Good Luck!
Looks like there was an A/C unit installed at some point and then removed. The last picture shows the compressor bracket and water controlled vacuum switch, likely the PO capped off the un-needed vacuum line. The best bet would be to re-route the vacuum lines using the non-A/C diagram and start from there. By the way, the water controlled vacuum switch is not needed on the non-A/C six cylinder car.
The temperature vacuum switch has nothing to do with having A/C or not...it's an emission thing. http://1bad6t.com/Maverick/repair/emission_controls_02.html#b
I don't want to pass any bad info, I went off this diagram that shows the 200ci engine using the water vacuum temp switch depending A/C or Non A/C application. I agree, it is an emissions component and IMHO not needed any longer regardless of application. BTW, I also see it has a hindrance when it comes to tuning, just another component check (does it work or not, does it leak, does it allow correct vacuum etc...). Correct me if I'm wrong, always interested in learning things, so fire away! http://www.1bad6t.com/Maverick/repair/70-72Vac.html
Kevin: I think Anne is planning on placing her A/C back in-service (according to her other thread). I'm not sure how much of the original system remains, but it could get interesting. Anne: I see you have a couple of Project Threads started. It would be best to just keep adding to this one as you complete stuff on your car. It makes it easier for us all to follow. Did you get a chance to look at the VIN?? It will tell you the year and the engine size. You can also add it to the thread HERE where everyone is posting VIN's to see where your car "fits" in the overall scheme of things.
I am going to replace that A/C system, albeit with a newer one as I believe it is now required. According to the thread on VIN's: 1973 Dearborn, MI Plant (3F31) the rest of the VIN is T558810 - not sure how that translates
T = 200CID 558810 = consecutive number, starting at 500,001 for the first Comet that year. So yours was #58,810 off the line. Thanks for sharing!
And thank you for the information. Oddly, it's comforting to know that I was right even if someone *may* have put a different bumper on at some point.
You have to be careful with all the diagrams out there. Most I've found show a different distributor than I have. Mine only has a single vacuum line for the distributor. It goes to the lower ported vacuum on the carburetor. The only other vacuum line I have goes from the PCV valve to the Carburetor spacer.
