This is a method shown to me by a radiator repairman years ago and has served me well. One can be easily baffled by test instrument companies but this simply tried and true method works for most cars (including full size passenger cars from the old school category). Adequate coolant flow through this type radiator core can be gauged very simply with the radiator in the car. Drain the coolant from the radiator (cool engine) then disconnect the bottom radiator hose from the radiator. Using clean and suitable water flowing through a 3/4 inch hose at 80 psi nominal/ 14-16 gallons per minute, insert the water hose into the fill neck of the radiator. The water should flow freely out the bottom of the radiator.
Radiators can be tested on a radiator test stand, these are expensive machines so not many shops have them or working ones at least. A find most shops that repair radiators just plug the bottom end ( cross flow turn it on its side) and fill the radiator with water and then unplug the bottom and watch the flow of water coming out. You really need to know the flow rate of a new radiator for your application as a base line. A big Detroit Diesel would be about 110 GPM (Gallons Per Minute) vs a pickup at about 55 GPM.

Does water flow through the fins in a car radiator?
no
How do you test a radiator to see if it is in working order?
If you suspect a problem, radiator shops can run a "flow test" after you remove the radiator and take it to them. If you don't want to remove and replace the radiator, they'll also do that part for you.
What is the function of a car thermostat?
The function of a car thermostat is to ensure that coolant gets to the radiator when it should. It blocks the coolant from reaching the radiator when the radiator is cold, and then lets it flow once it is heated up.
What will cause your radiator over flow to bubble and the car not running hot?
possible hole in hose

How can you tell where your car is leaking antifreeze from?
Call Around; Find A Radiator Shop or A Mechanic That Can Pressure Test Your Radiator. This Should Help
What is the purpose of the car radiator?
The engine of a car contains many passages through which water can flow. The water picks up excess heat from the car engine and then passes through the radiator, where it is cooled by the rapid flow of air. The cooled water then returns to the engine to pick up more excess heat. So to put it simply: the radiator cools the water which cools the engine.
Why is your car temperature Rising while at an idle and then goes down when you are moving?
When your car is at idle there is no air flow to cool the radiator, but when your car moves the air flow through the radiator cools it down. I would suspect the radiator fan is not coming on when it should. If the fan is working properly the engine temperature should stay fairly constant assuming the thermostat is also working properly.
How does the pully driven fan cool your car?
The fan directs air flow through the radiator so heat energy can transfer from the coolant in the radiator into the atmosphere.
How do you pressure check a car radiator for leaks?
You attach a pressure test kit to where the radiator cap goes, and pressurize the system. If it holds pressure, it's good.
Why do people put antifreeze into a car radiator for the winter?
So that the coolant can stay in liquid form and flow through the cooling system.
Why would car be overheating?
could be damaged or clogged radiator,low on anti-freeze,cooling fan is damaged,cooling fan cover was removed (it directs the air flow through the radiator)
