Vintage air heater valve

Installing Vintage air in my 67  Have all my ac lines and heater lines ran.  

Was going to fab up a small bracket to mount the heater valve that came with the kit and seems that the instructions contradict the proper way to mount it.  I have the arrow for flow so that's not the issue. Page 19 says mount the valve so the servo is facing down which puts the mounting holes(on side not top or bottom) perpendicular to ground but page 12 has mounting holes on top.

Any body install the vintage air valve and tell me or show me how you positioned it ?

Re: Vintage air heater valve

Well.....I just flat missed that in the directions and mounted mine wrong. If it's any consolation, it's got 4000 miles and lots of idling time without any issues.

What about using the supplied L bracket and fastening it to the lip where the cowl and firewall meet.

Looks like it's time for me to call Vintage air and get some information on why they want it like that before I make any changes.

Re: Vintage air heater valve

mine didn't come with a bracket and contents doesn't show it came with one  

I can fab one up I just need to figure out which orientation they really want this mounted.

guess I'll hold off until I can give them a call.  Be much easier for me to mount it with mounting holes on top but can make it work either way.

Re: Vintage air heater valve

Mine is supported by the hoses sitting next to the carb atop the intake. Been there for many years like that.  On Al McGee’s 65, I used some foxbody hoses to mount it in midair in front of the firewall. It looks good and works fine. It is so light, no brackets are needed. The hoses support it just fine.

Re: Vintage air heater valve

Im installing a vintage AC now.  Here's how I mounted mine.   Its how it was showed in the instructions.

Re: Vintage air heater valve

How cold outlet temps are you guys getting?  Vintage says 39-45 is normal. Mine only gets 48, and it is just not cold enough.

  I haven't had my charged yet.  Was going to take it in and my EFI was acting up.  So I think my EFI pressure pump is going out.  Once I have that fixed Ill have the system charged.

Since you have a fully charged system, if the compressor is putting out proper pressure, you probably have a problem with your expansion valve. You might have a microscopic piece of trash in the valve that limits flow through it.  Unfortunately, there is no way to test that theory except replacing the expansion valve.

Re: Vintage air heater valve

When I picked up my car from the shop it is cooling to 45º on high. Lowering the fan speed allows the temp goes down. Going back to R12 would also lower the temp. Forcing more R134a into it raises the high side pressure and could damage the system.

Re: Vintage air heater valve

I have one of the temp probes from the parts house with the needle sweep that I use to check temperature. It should be accurate enough. The air from my unit gets to 48 at the center vents, then the compressor kicks out. I doubt there is trash in the system and agree that 48 ain’t cold enough, the AC should be able to freeze the balls off a pool table!!

From looking at the instructions, it shows 36 to 46 for the working range at the center ducts. Most of the cars I’ve had will get to at least 40 degrees. The 69 F250 with the under dash unit would crank out 32 degree air, it was still R12.

The evaporator temp sensor converts to wires and ties back to the control board. It would be great it it was adjustable, but I doubt it. Make me wonder if it’s worthwhile to adjust the location of the probe in relation to the expansion valve, like farther downstream or creating less contact with the tubing. Both should allow the compressor to stay engaged longer and drop the temperature more.

I never did make time to call them this week about the mounting position of the heater control valve.

Re: Vintage air heater valve

I just got mine up and running on my 65, havent checked the temp but its cold and gets cold in minutes. have to turn it down with in 5 minutes and run at about 2 of the fan speed with alittle bie vent action.And I set my valve pointing up ? we are haveing some 95-100 tenps right now and I am doing in town driving. It is just as cold as my F150 or my 92 accord and that is a ice box

Re: Vintage air heater valve

Been meaning to post a pic of the heater valve mounted.  Used a heater hose from a fox body to go from upper outlet to heater valve then a long hose with a 90degree bend to go up to  water pump None of the heater lines or AC lines run on top of the engine which is the look I was going for.been meaning to post a pic of the heater valve mounted.  Used a heater hose from a fox body to go from upper outlet to heater valve then a long hose with a 90degree bend to go up to  water pump None of the heater lines or AC lines run on top of the engine which is the look I was going for.
