HD Expert CLASSIC Antifreeze/Coolant is a fully formulated, traditional chemistry corrosion inhibitor technology heavy-duty diesel engine coolant, and is formulated to include silicate, borate, nitrate and nitrite corrosion inhibitors, amongst others. It is phosphate and amine free.

Applications:
HD Expert CLASSIC Antifreeze/Coolant is suitable for heavy duty gasoline and diesel engines found in on-road, off-road, farm, mining and construction. HD Expert CLASSIC Antifreeze/Coolant contains borate, nitrite and silicate corrosion inhibitors. This product does not require a charge of supplemental coolant additives (SCAs) during initial fill or if the coolant is totally replaced. It is recommended in diesel applications that the coolant be checked and SCAs replenished to comply with the engine OEM recommendations. This product is specifically formulated to protect cylinder liners from pitting in heavy duty applications. The low silicate levels also provide aluminium compatibility for use in mixed fleet, gasoline and diesel, applications.

Performance Features and Benefits:

• Service life
  This product is suitable for up to 3000 hrs or 300,000 km in heavy duty application under normal operating conditions, whichever comes first, provided the coolant is kept in good conditions with the SCA levels in line with the OEM requirements.
• Corrosion protection
  This product protects coolant system metals such as copper, solder, brass, steel, cast iron and aluminium against corrosion. It also protects wet sleeve liners against cavitation and corrosion.
• Field compatability
  HD Expert CLASSIC Antifreeze/Coolant is miscible and compatible with other traditional fully formulated coolant products. It is also compatible with standard heavy duty SCAs and coolant filters.
• Phosphate and amine free
  This product is based on traditional inorganic inhibitors, including silicates, nitrites and borates. It is phosphate and amine free.
