Remembering to keep on top of regular checks of your car’s antifreeze can be difficult at times, however, with Dione G-12+ antifreeze, you don’t have to deal with your coolant for a long time.
Dione G-12+ Concentrate of RYMAX BV Holland is an ethylene glycol based engine coolant concentrate which uses Organic Acid Inhibitor Technology (OAT) and is free from nitrites, amines, phosphates, borates and silicates. Fleet trials have shown that when used at the correct concentration, OAT based coolants continue to provide effective corrosion protection for up to 250.000 km for passenger cars and 500.000 km in commercial vehicles.
Benefits
Unlike traditional coolants which employ inorganic inhibitors, Dione G-12+ Concentrate provides excellent protection against corrosion, overheating in summer and calcium deposits.
How to use
Dione G-12+ is a concentrated antifreeze. It needs to be diluted until 50% of its volume (see table below) with distilled or deionized water. Do not use tap water.
It is recommend that the coolant is completely replaced when the above mentioned mileages have been reached or after 5 years – whichever is the sooner.
