When do I need my heater radiator replaced?

The heater radiator is part of the heating system. It is the “battery” that heats the air coming into the cabin. The heater is connected to the cooling system, and if there are problems with it that are not solved for a long time, even the engine itself may suffer. When the car has been badly damaged in an accident, the heater radiator does not need to be replaced. This is obvious. It is also clear that the best solution to the problem is to contact those in the automotive recycling business: https://scrapmycarnear.me.

Signs of a faulty heater

If you observe any of the following, the car definitely needs attention:

Cold air blows from the diffusers even when the engine is warm;
The coolant level is dropping rapidly, it’s leaking into the passenger compartment and under the car;
The windows are sweating and covered with a greasy film.
When does a radiator need to be replaced?
The heating stops working properly most often for two reasons:

the tubes are clogged – over time, as well as if different brands of antifreeze were mixed in the system or water was poured into it; so the circulation is disturbed, the pressure increases excessively;
leaks – due to corrosion caused by bad antifreeze which must be changed, due to system wear and tear, mechanical damage and overheating.

The right thing to do in this situation is to replace the “battery”. Repairing a leak with a soldering iron or sealants can eventually grow into a new problem. To replace the unit with a new one will be the right decision in advance, because it is not as expensive as fixing the whole cooling system.

When can flushing the heater radiator help?

If there are no damages and leaks, you can theoretically do without replacing the old heater. It is advisable to flush the radiator separately from the cooling system. It is necessary to carefully approach the choice of means for cleaning and comply with all recommendations of the manufacturer. The choice of reagent depends on the nature of contamination, and on the metal of which the radiator is made.

Flushing can begin with a test blowdown with distilled water to understand the degree of clogging of the furnace. After we use a reagent, which will need to be flushed out of the system after the work. If everything is done correctly, the flow capacity of the tubes will increase, and the cabin will be properly heated again.

There is no universal way to flush a radiator without having to remove it. Vehicle designs vary, and it is not always possible to clean the installation both inside and out without removing it. What’s more, the layout of the heating system components can create some difficulty in maintaining and replacing it.

How to change the heater radiator yourself?
No one forbids the use of tips from the Internet on how to remove the heater radiator and replace it with a new one. However, be very careful. Note that the removal and replacement of heating units should be carried out by a professional at the service. This way you will save yourself from future problems with the cabin heating system, if you do something wrong.

Removing and replacing the radiator with a guarantee and inexpensive can be carried out by the hands of professionals at Automall (service station in Surgut, service station in Nizhnevartovsk).

If you have decided to replace the elements of heating system by yourself, here are some general recommendations. The main rule: refer to the technical documentation of your car, consider the recommendations of the manufacturer.

Tools you will need for work:

a set of screwdrivers and wrenches;
pail and watering can;
sealant for the shells fasteners.
Don’t forget to remove the battery terminals before interacting with any parts of the machine.

At the very beginning, to make things easier for yourself, you need to clarify the location of the heater radiator. You are lucky if it is under the hood closer to the windshield. Removing the heater radiator is more difficult if it is located in the cabin under the front panel in its central part. After all, in this case you will need to remove the entire torpedo to remove it. The interior parts are fixed by plastic clips, which are easily broken, therefore the panels must be removed very carefully.

Once the radiator is in range, you need to drain all the antifreeze from the system into a container. If the composition is clean, it can be reused with the addition of about one liter of coolant.

Now you can remove the radiator. Before you change the heat exchanger for a new one, you need to seal the attachment points of the casings with sealant, so that later there will be no leaks.

Be careful when choosing a radiator. Replace the old cabin heater should be a model from a proven manufacturer. Often makeshift manufacturers go to different tricks to make money. For example, if you came across a cheap copper radiator, it is quite possible that it is made of painted aluminum.

It is also recommended when installing a new heat exchanger to change the antifreeze, if its use caused problems with the heater or engine cooling.
