Heater Core- What Is It?
7
It is the heart of your vehicles heating system.
8
Its job is to take the help of engine coolant to
keep the cabin temperature warm.

You can think of it as a small radiator-shaped
component- made of conductive aluminum or brass
tubing.
10
If it stops working due to some reason, you will
encounter several problems.

Heater Core- Reason Why It May Stop Working
12
Blockage
13
The heater core is made of aluminum tubing-
through which coolant circulates.
14
If the tube gets clogged due to some reason, the
heater core will not work properly.
15
Rust/ Corrosion
16
If the inner lining of the conductive tubing
gets corroded, it could obstruct the flow of
coolant.
17
When that happens, the heat generation ability of
the heater core will be significantly reduced.
18
Leak
19
Yep. if there is a leak somewhere in the
conductive tubing, your heater core will
malfunction.
20
To resolve the problem, you must find out and fix
the leak.
21
Low Coolant Level
22
To keep your car cabin warm, the heater core
relies on the engine coolant.
23
And, if your car is low on coolant, its heater
core will not function properly.
24
Also, low coolant can cause engine overheating.
25
Therefore, check your BMWs coolant level
regularly and if necessary top it off.
