Disconnect a hose and fill it through the hose. Possibly the one to the water pump; that should be pretty accessible.
It flushes out old coolant and particulates which have formed in your cooling system.

Rust and sediment can accumulate in the cooling system. Flushing the radiator helps keep the cooling system clean.
Not enough coolant in the cooling system - Improper ratio of coolant to water in the system - Improper or failing radiator pressure cap - Cooling system water pump may be failing - Radiator fins may be dirty or blocked. - radiator cooling fans are not operating correctly - cooling system is dirty and may need flushing.
Blocked radiator, low on coolant, stuck thermostat, air in cooling system
Enough to shag it, spoken from experience ;) The average automotive radiator is actually two radiators in one - the larger section for the engine's coolant and the smaller section for the cooling of transmission fluid with some having a section for the cooling of power steering fluid. The only valve in a radiator is one at the bottom for draining and flushing of the engine coolant; the rest of the radiator's interior tubing is clear and un-restricted. landcranch
Low coolant? Cooling fan not working? Bad thermostat? Cooling system airbound? Water pump not circulating coolant? Radiator core plugged or restricted? Bad radiator cap?
A 2001 Volkswagen Beetle only takes a specific type of coolant. When flushing or just topping off the radiator in this vehicle be sure to use G12+ coolant to ensure proper cooling for the vehicles engine.
Low coolant? Cooling fan not working? Radiator restricted or plugged? Water pump not circulating coolant? Defective radiator cap? Low coolant? Cooling fan not working? Radiator restricted or plugged? Water pump not circulating coolant? Defective radiator cap?
If the problem your having is in your 'cooling system' , flushing it out could help out a lot.
You may have to replace the cooling fan relay or the cooling fan itself, I had the same problem and I first replaced the relay and it helped but then the cooling fan went out and I repalced it and now everything is fine.
As coolant cycles through the engine, it absorbs heat from the engine, after which, it continues through the cooling system back to the radiator. As the coolant passes through the radiator, the heat is exchanged to the ambient air by way of airflow through the radiator fins (this is why it's important not to bend the radiator fins).
