When the engine of your BMW is running, it will generate a lot of heat and cause significant wear on its metal parts. Due to these reasons, every model of BMW has a well-functional cooling system that has coolant which is the combination of an equal amount of water and antifreeze to dissipate the heat generated by the engine. When the coolant level is lowered in your BMW, you will notice the problems defined in the following slide.

2. Among the several
important fluids in the
car, the coolant is the
most useful one.

11. Due to the low coolant
level in the engine, the
engine is overheated and
causes permanent or
irreparable damage.

12. Modern cars have a
central computer
system that can shut off
the engine when the
coolant level is lowered.

18. When the coolant level is
lowered, your car is losing
acceleration and consumes
more fuel than required.

20. Running the engine with low coolant can affect the
functions of the heater system and damage it entirely.

21. If you found that hot air is not produced from the heater,
then make sure that the engine either has low or no coolant.
