Coolant recovery tank

-
I bought this one on Amazon. It was around $50. The inlet is at the bottom. There is a second smaller tube that sticks out at the bottom and runs inside up to about an inch from the top and acts as an overflow. If you have the correct rad cap it functions perfectly as a recovery system and pulls the coolant back into the rad. If you have more room than I had, a larger capacity would be nice.

I too have this one and it works as described by qkcuda. I use a stock PSI cap too and the type of cap matters, I think it has two springs instead of one. Its been a while since I did my homework on the topic.
 
The one that exploded on me had two tubes. One of the tubes was open at the bottom, but extended almost to the top of the tank. The other was shorter and was connected to the radiator overflow hose. The problem with the tubes is that they’re smaller inside diameter than the radiator outlet.

like I said, I have a feeling I may not have had it set up correctly, which is why I started this thread in the first place.
 
I have 2 running cars, stock 318 and the other one is a 418 stroker, neither car needs an overflow tank. The radiator seeks its own level and stays there, just above the tubes, they don't over heat either. My Hemi car, do not expect it to be an issue either.
 
I went with a Dorman 54002 kit from the local O'Reilly's. My radiator's overflow hose connects to the bottom feed on the Dorman bottle/tank. It works well for my needs.

I have at least a very similar one to qkcuda. This one has enough capacity. I had a smaller one and it was just barely enough so the volume would go down over time. This one works perfectly. Mine might be a taller one. I have it on the back of the radiiator due to the height.
 
My dad made one out of an orange juice bottle, he had it on his / my dart since the late 70s when I got his car it was one of the first things I removed.
My neighbor donated a tequila bottle for my tank. Been doing it's job for years now.

'73-'76 A bodies had them.
They looked similar, but there were 2 different versions. The '73 had 2 rubber lines from the cap, 1 to the radiator, and a discharge line clipped to the side of the body.
'74-'76 had one line to the tank from the radiator, the overflow was a molded-in part of the body.
The mounting bracket was slightly different between the two, also.
They are interchangeable.
You will also need to use the later radiator cap for the system to function properly.
Some pics I pilfered from other threads:

They retrofit just fine onto older cars/radiators as long as the correct radiator cap is used.
The only real mod you have to do on the early cars is drill a hole in the top of the passenger frame rail- 1/2" IIRC. This is to accommodate the small locating "finger" at the bottom of the tank.

You may or may not need to drill 2 small holes- 3/16" or so- in the upper radiator yoke for the 2 small bracket studs; some cars have them, some do not.
In this pic you can kinda see where I even able to mount one in my '66; the bracket holes were already there (don't know what they would have been for in '66, but they fit the bracket perfectly), I just had to drill the top of the frame rail. The horns got relocated to the driver's side (those holes were already there, too).

I've put these in my '66 (as mentioned), '68s, and a '70; so I know they fit and work all along the A body production run.

What did your AC/Alternator bracket setup come off of?
 
What did your AC/Alternator bracket setup come off of?
That particular setup came off a '92 D250 with a 360, but has been slightly modified to mount a Sanden compressor instead of the Chrysler C171 rotary compressor; but otherwise uses all the same pullies and belts from that motor. '91 and earlier 318s had the same setup, last of the LAs and after that it was all Magnum. As I recall, late Dippys and Gran Furys etc. had similar bracketry.
It's also nice to be able to run the big (90a+) late Denso alternators (with the appropriate wiring mods, of course) since these brackets mount the alternator high enough to clear the head/valve cover.
