4.9.2 Handling GENCOOL EG
GENCOOL EG should be stored at ambient temperatures, while periods of exposure to temperatures
above 35°C (95°F) should be minimized. GENCOOL EG can be stored for a minimum of 5 years in
unopened containers without any effect on the product quality of performance.
GENCOOL 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 GENCOOL 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.
GENCOOL 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 GENCOOL EG.
