Handling PARCOOL EG

PARCOOL EG should be stored at ambient temperatures, while periods of exposure to temperatures
above 35° should be minimized. PARCOOL EG can be stored for a minimum of 5 years in unopened
containers without any effect on the product quality of performance.
PARCOOL EG is compatible with most other coolants based on ethylene glycol, but you only get the
benefits of 5 years protection when its used on its own. Exclusive use of PARCOOL EG is
recommended for optimum corrosion protection and sludge control.
For simple density-measuring of Ethylene Glycol and Propylene Glycol in general the standard
available 'density' measuring devices are used to measure the concentration of EG. In case a device
is used to measure EG, no PG can be measured afterwards as a result of the difference in the
density. More specific measurements can be done by the use of a refractometer. This device can
measure both EG and PG. A mix of both products will be show unreliable results!
Mixed EG coolants with identical glycol type can be measured by use of a refractometer as well as
the 'density' system. The mixed coolants will be considered as one product.
The use of distilled water is recommended. If you have exceptionally soft water it would be
acceptable, as well. Basically, the engine metals are going to corrode to some extent no matter
what water you use, and hard water will encourage the resulting metal salts to precipitate.
PARCOOL EG comes as a pre-mixed coolant to safeguard the quality of the complete product.
It is recommended that topping up of the cooling system is always done with PARCOOL EG.
