I understand.
But my recollection of the way the Classic Air system works is that it always puts the compressor on - no A/C button to push. When the system turns on it always runs the compressor. All the sliders do is change the fan speed, the temperature of the air and where it blows.
I don't...
No. This is the way the system is designed and is supposed to operate. The compressor removes humidity, so when you are defrosting, having the compressor on while doing so helps keep the windshield clear.
It is a Classic Air system with Bouchillon Engineering brackets to relocate the compressor down low.
I can't say why it is oriented that way. I simply put the holes where they were needed based on the template Classic Air provided.
Here is the template
Here are a couple of the heater control...
The goal of my car has always been to look as stock as possible while still incorporating a number of modern day touches to make it better.
I chose to hide my A/C hoses in plain sight. My compressor sits low (below the alternator) and I simply routed the hoses up and let them "mingle" with the...
Too late now to absorb all in this thread. Plus, I've had a couple of beers too :poke:
But I'll be following along. I installed a Classic Air system in my 70 RR. Maybe I can help as you go along...
:popcorn:
No and No. The firewall insulation was a separate kit. I can't remember where I got it from, but it was a large kit with all the insulation needed for the car.
The Classic Air kit came with a paper template for drilling holes. You can actually go to their web site and download the template if...
My 70 Road Runner never had A/C. The mice had overtaken my non-A/C heater box anyway. The Classic Air system I installed replaced pretty much everything to do with my heating system, except for the defrost vents in my dash.
Here are some pics. First, here is the stock, non-A/C firewall...
I added Classic Air A/C to my 1970 Road Runner when I restored it in 2015. My system has been flawless and has worked great.
I put my under dash airbox in before I installed the rest of my dash. I believe it is significantly easier to do it that way rather than adding it later. Whatever you do...
My 70 Road Runner has Classic Air, and the right hand side fresh air vent has a block off plate and is partially blocked by the heater. I believe this will be the same on any B-body.
For years, I have had an extra drivers side vent that I could maybe modify to fit on the passenger side. The...
When I drove my 70 Road Runner across country in 2015 we drove sustained speeds of 90+ MPH through Kansas with a top speed of 108 MPH. Our 90+ speeds lasted about 2 hours or so. There is no reason, from a cooling system perspective, that your car shouldn't be able to do the same.
Respectfully, I think you are overanalyzing.
A very lean running engine can cause heat issues. But you have already seen a good improvement based on cleaning out the cooling system. I'd put the new radiator in it and drive it. My bet is the overheating problem has been solved. If not, then we...
People add larger radiators all the time, and since yours is not original, maybe they did for your car as well? You should first check the core support opening width. A car originally equipped with a 22" radiator has a smaller opening than one with a 26" radiator. I just very quickly and roughly...
Sounds like you have a 22" radiator, which makes sense if your car originally has a 318 (and no A/C). The heavy duty cooling radiators that are 26" wide have the top return hose on the left as you look in the engine compartment.
I used the Classic Air "Perfect Fit" system that I bought and installed in 2015. It's been ice cold and has worked great since then - no issues at all.
...- all it does is regulate the engine temperature, ASSUMING YOUR COOLING SYSTEM CAN SHED THE HEAT.
So if you had infinite cooling capability, a 160* thermostat will cause the engine to run slightly above 160*. Same thing for a 180* or 195*. On the other hand, if you are running a 160*...
The bracket to mount the compressor is from Bouchillon Engineering. When I bought my system from Classic they were well aware of it and just substituted it instead of the standard brackets for a small price difference. But I don't see why you couldn't use it with either a Classic or Vintage...
I installed Classic Auto Air in my 70 Road Runner. I modified the system to hide the compressor as much as possible. Classic Auto Air was great to work with so I could get the customized parts I needed to make it all work.
My first A/C post for my restoration thread is here (but there are many...
There is a pressure switch that does not allow the compressor to turn if it has no pressure. It is a safety to protect the compressor. If you short the switch, the compressor should come on. When a tech provides pressured Freon into the system, it will engage on its own.
There are some places that do not require that you leave it. I didn't want to leave my 70 so I asked a local "old timer" service station if they could charge my A/C while I waited. Of course, I let them pick their time, and then I stayed with the car the whole time (of course, this "old timer"...
