How to determine that the radiator is clogged? Checking whether there are problems with the heater radiator is quite easy.

1. First you need to make sure that the cause of the heating-system failure is precisely the heater radiator and not another component. Then confirm that the thermostat and pump are working properly.

2. Warm the engine up to operating temperature

3. Locate the two hoses in the engine bay by opening the bonnet

4. Check whether these hoses are at normal temperature. If one is hot and the other cold, the radiator needs flushing

5. Even if both hoses are hot, the cabin can remain cold because coolant does not reach the clogged radiator. In this case we recommend replacing the heat exchanger.

6. To check pump serviceability, start the engine and open the expansion tank of the heat exchanger. If you see coolant flowing from the radiator into the tank, the pump is working correctly

Why the radiator becomes clogged

1 the unit has been in service for a long time and is reaching the end of its life

2 diagnostics were not carried out in time

3 the coolant level is not brought to the required mark

4 use of unsuitable, poor-quality antifreeze

5 continued entry of dirt particles from the cooling system into an already clogged radiator

6 corrosion due to insufficient corrosion inhibitors in the antifreeze

7 using water that contains many salts

8 entry of chemically active fluids—fuel or oil—into the cooling system

How does the heating system work?

The heater operates on the same principle as the radiators in your home: its main task is to warm the cabin in cold weather.

Usually the heater is not switched on in summer and spring, so you can say it actually works for only one season. When the temperature begins to drop, we recommend checking the heater radiator in advance.

The primary task of the heater radiator is to supply warm air to the cabin. It has a rectangular shape and is most often made of aluminium or copper.

The key indicator of a radiator’s serviceability is correct coolant circulation between the pipes.

What a heater radiator consists of

Inlet ports
Round or flat pipes secured by plates to enable coolant circulation. If the pipes are flat, the fluid cools better, and such radiators are accordingly more expensive. This structure directs the flow to heat the cabin as efficiently as possible.
Hoses. Antifreeze comes from the engine, cools down and transfers heat into the hoses
Filter
Fan

Heater-radiator cleaning procedure at VAG Master

We perform radiator flushing in Kyiv using dedicated equipment that maintains the temperature and pressure required for the coolant.
We drain the antifreeze.

Depending on the problem’s complexity, two methods can be used:

With heater removal—the radiator is removed together with the valve. The advantage is that we can assess the entire cooling system and clean the radiator thoroughly.
Without heater removal—the heater can be cleaned without dismantling, but the effect is much weaker and shorter-lived.

We use special chemical agents for cleaning.
Before cleaning we prepare the necessary tool kit. A water pump is used to make the liquid circulate within the heating circuit.

For an hour we circulate the fluid through the radiator in one direction and then the same time in the opposite direction. We change the cleaner and repeat from the start. Finally everything is rinsed with clean water.

You can take advantage of heater-radiator flushing in Kyiv at our network of service centres.

To do this you need to:

call us by phone
submit a request on the website
come to our service station (but it’s better to call in advance)

I asked to have the stove radiator flushed because the heating in the cabin was weak. The craftsmen quickly completed the work, checked everything after the procedure. Now the stove heats much better, the result is noticeable immediately.

I had the stove radiator flushed before winter. I liked the service — everything was done neatly, they explained the cause of the clogging and gave recommendations. The cabin is now warm and comfortable.

I came because of uneven heating. We flushed the stove radiator, checked the system and tested it after work. After the service, the heating works stably, without interruptions.
