Have a 1971 dart swinger, 318 have been having cooling issues put a campion 4 row aluminum rad in helped only a little.have not been running a resivior for rad. guy today said that is why I'm overheating, will that make a difference ?
 
Guy's an idiot. A reservoir, as it's spelled, will not make a car run hot, nor will it cure one. It is a good idea though, so you don't poison any stray animals.

What's the rest of your cooling system consist of?

All the reservoir does is allow the recovery of coolant pushed out while running, and it only does that as it cools down and causes a vacuum in the radiator.
It makes zero difference in cooling while running.
 
Define your overheating. Running hotter then normal or puking coolant?

If you fill a radiator to the top its going to push coolant out of the overfill until it finds its happy level. A coolant recovery collects the overfill then lets it back in when the coolant cools off. Benefits are twofold. It keeps coolant off the street and oxygen out of the cooling system
 
Not an absolute necessity but probably a good idea. Older vehicles never had them but fluid level should be approximately an inch low, if not it will overflow and get there bu itself. Do you have a fan shroud and is your thermostat working properly. How about a thermostatic fan clutch, is it working?? If any of those , could be the problem with your heating.

Make sure your pullies turn the water pump faster than crank speed.

And a good two core will cool circles around a four core.
 
We should assume your new radiator has a new recovery type cap on it too. Adding that plastic bottle to my 67 is one of my best/favorite moves. At least 2 years since I last removed the radiator cap. A glance at that bottle tells all.

I know this is ancient history, but what kind of “plastic bottle” rig did you set up? I want to add one to my 71 demon. The radiator overflow tube goes towards the driver side, where the battery is also installed so there is little space.
Thanks

My original 67 radiator has over flow tube to right side. I had to relocate 1 of the 2 horns to mount a small hex shaped bottle from Advance auto parts. I guess you can route the rubber hose around and to the right. I dont think you would want a lot of moisture near battery terminals anyway.
 
If you are not checking the water level frequently, it could be getting low.

A recovery tank will make that less of an issue.

I'm using a $5, 48 oz, water bottle from wal-mart.

Works great, however a 32 oz bottle was not large enough.
 
the factory tank from a 73 up Dart will fit very nicely, over on the passenger side. On my 68 Barracuda I just had to drill a large locating hole down in the core support. But yeah, I did have to relocate the horns. Actually, I took them off and threw them into a box up in the attic, with all the other horns that I have relocated; horns just get me into so much trouble......
 
An additional recovery tank on a non-originally equipped car (as my '71 Demon) can be useful to collect an eventual liquid overflow. Ok.
But, in case of use of a tank from an other car (with a cap and a plunger tube), will the liquid automatically sucked back to the radiator?
 
As long as the overflow tube is below the water level and the cap is correct for a return system, yes.

Those "engineered" bottles that have the hose connection plumbed to the bottom of the container guarantee the hose is always at the lowest level.

I have mine cut so that it is about 3/4 of an inch from the bottom of the bottle.

Works very well.

I try to keep the bottle 1/2 full so that it will hold overflow and also have coolant to suck back in.

Adding the bottle has lengthened the time from checking the radiator level from every drive to about every 5th or 6th drive, and instead of removing the cap, simply glancing at the bottle.

Does anyone know if the cap that came with the Champion radiator would work for coolant recovery? If not, what cap should be used? I remember the "old days" when the coolant recovery kit came with a cap that said coolant recovery.

Does the cap have 2 rubbers, if so, yes it will work for coolant recovery. Kim
