You dont menton the exact type of vehicle but generally a lack of flow of coolant is normally the water pump unit malfunctioning. This fits towards the front-bottom-end of the engine block when you have the hood opened. It has a pipe feeding water into it from the radiator. The pump unit has a little 'fan-shaped' device in it which it uses to pump the coolant and since 7 or 8years ago, VW started to use units that have plastic fan blades (they used to all be metal before). These plastic units are more prone to malfunction.

How are you filling it up? Thru the radiator cap? Not the best way all the time. Best is to take off the top rad hose and pour coolant in the hose until the engine fills up. Then put that hose back on.(you have now put coolant on one side of the "thermostat" - a device that opens and closes depending on the temperature of the coolant>that comes in contact with it< If an air pocket is there from say changing the thermostat or blowing out all the coolant thru a bad hose....it will not open=no coolant circulation. /// VW rabbits are known to have that situation///
Then pour coolant into thru rad cap . This will put coolant on the other side of the thermostat.
Also make sure that the heater valve is open(maximum heat) so that the heater core fills as well.
Once you done all that and then add half full in the overflow container....start the car and let it run for awhile. Want to see the thermostat open and any air pockets will get pushed up to the rad....which may mean more fluid needs to be added later. You will not see it circulate, just watch the temp. gage and see if it overheats. If it does not after 15 min. you should be fairly safe to drive it.

The radiator definitely holds the water/coolant and the pump circulates the aggregate in the process the engine. Upon returning to the radiator, the water is cooled from air passing in the process the fins of the radiator. The pumps interest is to flow the aggregate to confirm that the nice and comfortable water to sit down back hence, the engine is then cooled.

I notice that question is listed under Volkswagen. Well if it is an older beetle it is an air cooled engine. If it is a newer VW it is liquid cooled. I would check the fluid level in the radiator and the overflow. If that doesn't work check to make sure the water pump is good. I would then look into the thermostat. Make sure it is opening when it gets hot. Thermostats are inexpensive little gremlins that often get overlooked. Good luck and I hope this helps.

Had a VW in the shop the other week with an overheating problem. It turned out to be the water pump. It has a plastic impeller on it and it had broke and fell off.

Sounds like a bad water pump. Could be the pump or belts. Could also be low or bad coolant.
Some water pumps are easy to replace, some are not, depends on the car model.
