HOW IS COOLANT CHEMICAL WORKING IN
HEAVY DUTY VEHICLE?
https://saqrme.com/

The phrase “engine coolant” refers to a
broad category of fluids used to cool
down engines. The radiator dissipates
heat from the internal combustion
engine through the engine coolant, a
crucial component of all HDV engines. It
keeps the engine from overheating and
breaking down as a result. Engine
protection against oxidation, corrosion,
corrosion pitting, scaling, and clogging is
ensured thanks to the coolants
chemical composition.

THE COOLANT’S COMPOSITION

Deionised water, glycol (often ethylene glycol or propylene glycol),
and chemical additives are the primary components of coolant. It is
your responsibility to make an informed decision about the kind of
coolant you use. The decision is based on the engine’s frequency
and exposure to various environmental and temperature
conditions. An ideal coolant does not freeze even in freezing
climates to avoid boiling off into the atmosphere owing to
overheating. Insufficient cooling is to blame for at least 40% of
engine issues.
COOLANT TYPES:

Depending on the use and
application, there are at least
three kinds of coolants used
in heavy-duty vehicle engines.
The following are their
names:
COOLANT IN THE OLD-FASHIONED STYLE

Corrosion-inhibiting coolants protect metals like steel, aluminium,
and copper against corrosion when used as standard or
conventional coolants. This coolant chemical is excellent for heavyduty engines since it covers the wet sleeve liner against corruption.
Green or purple are the most common colours for these
refrigerants. The coolant’s corrosion inhibitors degrade quickly, and
as a result, their usefulness is limited.
COOLANT FOR OAT (OUTDOOR AIR TREATMENT) SYSTEMS

Organic Acid Technology (OAT) is a silicate-free and long-lasting
coolant. The carboxylate acid corrosion inhibitors, employed in
these fluids instead of conventional ones, degrade at a much slower
pace. Supplemental Coolant Additives do not need to be refilled
regularly, and one may last the engine’s lifespan with only one refill.
They’re usually red or orange, depending on the kind. In addition, it
protects metal superbly at high temperatures.
HYBRID COOLANT TYPES AND APPLICATIONS

OAT corrosion inhibitor technology is
used with conventional corrosion
inhibitor technology in this coolant
technology. Yellow and red are the
most common colours for this kind
of coolant.

Coolant filters, which are separate from
the coolants themselves, are part of the
automobile system and help keep the
coolants clean by removing pollutants
from the outside. They’re also utilised to
replenish the coolant’s exhausted supplies
by
adding
Radiator
Cleaning
Chemicals like SCA. Only buy filters from
well-known and certified automobile filter
manufacturers if you want the best
solutions for your engine.
