Vintage air gen iv install for 69

Getting ready to install gen IV in my 69. Trying to find best, easiest way to install. Have not purchased bulkhead yet and the front end is not on the car.
Do I need a bulkhead or just strainght run?
Best hoses to use, fittings, etc?

Any help or links is greatly appreciated.

Thanks, J.A.

Re: Vintage air gen iv install for 69

There are several ways to install, and none wrong. Depends on the look you're after.
I ran mine in the fender, through a DSE heater delete bolt on plate, where the blower hole would be. All hoses run to the evap assembly with no short hardlines.
Heater hoses run direct to the evap with short barbs ordered.
I ordered a compressor that has rear exit ports for the #8 and #10 hoses, and the fittings are ~100 deg that turn down and hoses run underneath.
Definitely not the easiest, and would be expensive at a shop, but short of a full on firewall smoothing which I don't want, looks awesome IMHO.

Forgot to mention I have already smoothed firewall and fresh new paint.

Re: Vintage air gen iv install for 69

Do you want to hide the hoses or in sight?

Re: Vintage air gen iv install for 69

If I use a bulkhead, then show the hoses.

If I run straight thru firewall as I have seen some done, then I would like to hide them. Do the grommets I have seen hold up to wear and tear?
Also will the fittings fit thru the grommets also?

Thanks.

Re: Vintage air gen iv install for 69

I am getting ready to do the same. Does the kit use any of the old heat exchanger? Do you have any pics? I would like to know how hard the install is.

Re: Vintage air gen iv install for 69

I put the grommets on the hoses before crimping the fittings.
Whether you install grommets before or after fittings somewhat depends on your type grommet , size and quality.
You definitely want to do a mock up before any crimping is done.
I am guessing the grommets will last until the rubber gets hard and cracks, probably 15-25 years.

Re: Vintage air gen iv install for 69

I have recently done this on my 69 and VA Gen IV. First you must decide through blower hole or bulkhead and go with the plan. Wish you hadn't already got the firewall done. The VA IV unit requires mounting screws that will show through the firewall. We mounted the unit the way instructions stated then welded studs in instead. Therefore not showing any screws. I went through the fan blower hole by Frank at Prodigy Customs suggestion. Less fittings and chances for leaks. I installed the grommets into the fireswall first and gently warmed them up with a heat gun. Then ran my hoses through. Also beforehand think of how you want the interior kick panel and hoses to look. I have a black anodized bulkhead that I did not use. PM me if interested. I thought of going this route but changed my mind. If I did anything different it would be to buy a blank passenger side kickpanel and maybe install 4 grommet holes there also. To clean it up. Also remember if you go through the kick panel the evaporator hoses connected and kick panel go up somewhat at once. If you do as I did use some dum dum around the back side of the hose panel ( I think its for a chevelle) or kick panel. Outside water(hose or rain) runs down the cowl and in the area where the hoses go through the fan hole. So seal it up. Don't want water in the interior. One more thing. Install the door curtusy light switch and a pigtail wire, it might be harder to do with the kick panel installed. Here are some pics of my install. Hope this helps some.

Re: Vintage air gen iv install for 69

I did the same thing that Ted did. My car was an AC to begin with so I put the "round" cover back on the kick panel to hide the hoses. You can get that piece in the after market. The cover for the fan hole is available from VA. It is for a 67 Chevelle and works great. They will help you for whatever you need. I ran the hose to the drivers side to the compressor. It is 12' long and I ran it under the radiator core support in the "made for" space so there are no visible hoses on top of the engine or my smoothed firewall. No wires either showing. . . just the BB!

Re: Vintage air gen iv install for 69

Just wanted to add that my accessory set up is a March mid-mount serpentine belt set up. So my comp is on the pass side. If you are hidding hoses or doing custom set up. Measure and re-measure your hoses before you crimp on the fittings. Also my heater control valve is installed right about where the hoses come out from behind the fender. Easier access if I need to get to it.

Re: Vintage air gen iv install for 69

Thnks for all the help. Ted thanks for all the pics. Makes it a little less overwhelming.

Well started installation of the evaporator today.
Fabricated a brace from behind the unit to the area right below the firewall. Seems pretty sturdy.
Working on the 4 holes for the lines. Not using a bulkhead after all.

Do you have to fit the lines on the evap. and then raise it in place before bolting it down?

Yes you will have to have the evap on the floor to hook the hoses up but you will need it in place to get the correct length on your hoses.

Hook your hoses up on the inside and route them to the compressor and accumulator to get the right length.

Also put masking tape on the hoses and mark a line across the tape and metal part of the fitting. This way you have a reference where the fitting needs to be on the hose when you have them crimped.

Re: Vintage air gen iv install for 69

Mike already answered you, but again yes on your last question. Retro fit your evap and run your lines where you want them. Do it several times if need be. Don't know where your comp is located, but if you plan on running your lines behind the fender. Make sure you have enough line. It helped me by having the driver side fender on. That way I could have a better visual on where my hoses were actually going to come out at. You don't want to have your hoses cut and crimped, ran behind the fender, mount the fender and then find out your hose is to short.

Re: Vintage air gen iv install for 69

Probably right on the grommets lasting quite awhile. Are these special grommets or regular auto parts stuff?

Will all of the holes be the same size? 1 inch?
Are the hoses the same size diameter? Can smaller diameter hose be used?

The cover (by the kick panel) being used by some from a 67 Chevelle, is this a VA product?

By the way Mike thanks for selling me the back seat off your 69.

Thanks, J.A.

Re: Vintage air gen iv install for 69

Is there an ideal place to drill the holes - high, low, right, left?
Making it easier to run and bend hoses inside.

Thnks.
