Opticool Antifreeze Yellow is an ethylene glycol-based engine coolant concentrate, which uses Organic Acid Inhibitor Technology and is free from nitrites, amines, phosphates, borates and silicates. It is BTC Classification Type 4E.
Fleet trials have shown that when used at the correct concentration coolants based on Organic Acid Inhibitor Technology continue to provide effective corrosion protection for up to 250,000km for passenger cars and 500,000km in commercial vehicles. It is recommended that the coolant is replaced when the above mileages have been reached or after 5 years. Opticool Antifreeze Yellow provides excellent protection to engine cooling systems, whether they are predominantly of ferrous or aluminium construction.
Unlike traditional coolants which employ inorganic inhibitors, Opticool Antifreeze Yellow has excellent hard water stability and very low inhibitor depletion rates.
Opticool Antifreeze Yellow is suitable for all year round usage in automotive and commercial petrol and diesel engines and certain industrial applications.
