Autumn has come, and with it cooler days. When you don't feel the thermal comfort behind the wheel of a car, heating comes in handy. Like all components of a car, it is also susceptible to breakdowns, sometimes leading to the destruction of the main components of the car. What to check before starting heating for the first time in autumn? Read our tips!

Heating makes driving easier at low temperatures. Unfortunately, like all car components, it sometimes fails. A common cause of malfunctions is a malfunction of the thermostat or air in the cooling system. Regular checks of key vehicle components can in many cases avoid high repair costs.

How does heating work in a car?

The heater is responsible for heating in the car - a structure consisting of several thin finned tubes through which liquid flows from ... the cooling system. This fluid heats the air passing through the heater, which is then directed (often by a fan) into the interior of the car.

Sometimes the coolant temperature is too low to heat the vehicle interior. This issue has been resolved electric pen, which is an accessory for many vehicles. It heats up the air until the coolant reaches the optimum temperature.

Which parts of the machine to check?

Cooling system

The aforementioned cooling system is the first component of the car that is worth checking. Sometimes they appear in it air bubbles that prevent effective heat circulation. Make sure there is no air in the cooling system before turning on the heating in the fall.

The process is extremely simple - just remove the radiator cap, start the engine, set the heat to full blast and wait about a dozen minutes. If bubbles appear on the surface of the liquid, it is necessary to remove air from the cooling system. You should be patient and let the liquid collapse (remembering to replenish it), filling the places previously occupied by air bubbles. Of course, you can repeat the entire operation in an hour. You must also remember that bleeding should only be done on a cold engine.

fan

It happens that the radiator fan is too loud or does not work at all. The causes are usually mechanical damage, worn bearings or dirty blades. It is worth looking at the fuse and power harness - this will allow you to determine if the problem is with the fan motor or not.

thermostat

If the car does not have a temperature gauge, it is recommended that you check the thermostat yourself. The experiment consists in checking the pipe connected directly to the radiator (this must be done immediately after starting the engine). By default, it should be cold and gradually warm up. If it heats up immediately, the thermostat may need to be replaced. For prevention, it is worth changing this element every few years.

Control system

The electronics in the car are extremely prone to malfunction. Malfunctions are often found in the air control system, so it is good to check this by pressing the subsequent buttons on the air conditioner panel. Defective flaps, previously inaudible crackling, or, conversely, silence should be an alarm. A malfunctioning control panel is a complex problem that is best resolved by a mechanic.

What to check before starting the heating for the first time in autumn?

It is very important to regularly check the condition of your vehicle. Try to prevent, not cure, so check the operation of the critical elements of this system before the first heating in the fall. You may then be able to detect the malfunction or notice the first symptoms of a malfunction of this component, thereby avoiding costly repairs or replacement (for example, the engine is jammed due to a blocked thermostat).
