Depending on the OEM requirement, some heavy duty engine types
demand use of a fully formulated coolant that meets ASTM D-6210
specification
transfer properties, radiator clogging, water
pump seal damage, toxic and low aluminium
corrosion protection.
Organic inhibitor technology has low
additive depletion, better cooling efficiency-no
deposit/optimum heat transfer, longer drain
interval/life time and excellent aluminium
corrosion protection.However, they are more
expensive than mineral based and are not
compatible with mineral inhibitors.
Presently technology advancement has been
a bigger driver of coolants trends as shown
below:One popular question from coolant
users is whether different coolants can be
mixed. I discourage mixing because of
issues with compatibility. Mixing can result
to destabilisation chemical equilibrium of
inhibitors, compromise corrosion protection
from mineral to organic. This is because organic
inhibitors have detergency properti
