What does an EGR cooler do?

the chamber breaks chemical bonds, forming new molecules. Nitrogen oxides (NOx) and
ozone (O3) is formed when this heat combines nitrogen and oxygen atoms from
air. NOx can form
smog, and when mixed with water can form acid rain. The ozone layer protects us from
ultraviolet light, but at ground level this gas can cause breathing problems,
especially for those with sensitive lungs/respiratory problems.

EGR

The body has
a hollow tube or series of tubes through which hot exhaust gases pass.
These pipes are surrounded by several coolant passages. Heat is
transferred through the walls that separate
exhaust and coolant, supplying cooler, inert exhaust gases ready for
lower peak combustion temperatures. Exhaust gas flow through EGR
The cooler is controlled by the on-board computer through the EGR valve.

transferred to the vehicle's cooling system. This extra warmth is just
dissipated through the radiator. However, since the EGR cooler connects
exhaust and cooling systems of your engine, malfunctions inside the cooler can lead to
loss of coolant, overheating and engine damage, among other failures.
What happens if your EGR cooler fails?
