Engine Coolant - HDD

Product Description HDD Coolant 50 has been specifically designed as a general purpose heavy duty cycle engine coolant suitable for diesel trucks, buses, marine, locomotive and static engines as well as mining equipment with both ferrous and aluminium construction. It is a low silicate and amine free formulation, which contains a pre-charge of supplemental coolant additive (SCA) for added protection against wet cylinder liner pitting. It can be used alone, or with an SCA for extended service applications. Recommended Concentration HDD Coolant 50, pre-diluted to 50% v/v, contains sufficient inhibitors to enable it to be used as an initial fill fluid without the need for a pre-charge of supplemental coolant additive. Service Life The recommended maximum service interval without recharging the inhibitor system with an SCA is 240,000 kms (or 2 years) for off-road engines. In instances where extended service is required, HDD Coolant 50 requires ongoing maintenace with an SCA during its service life. Where an SCA dose is required, use the SCA appropriate for that engine. NOTE: Do not use HDD Coolant 50 with the Scania SCA or Glycool 350 coolant as they are NOT compatible.
