    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.
