Doosan Compressor HP1300WCAT-T4i

WARNING: Do not remove the cap from a HOT engine radiator. The sudden release of pressure from a heated cooling system can result in serious personal injury.

The engine cooling system is filled at the factory with a 50/50 mixture of water and ethylene glycol. This permanent type antifreeze contains rust inhibitors and provides protection to --35° F (--37°C).

The use of such a mixture is recommended for both summer and winter operation. When using water alone, be sure to add a reputable brand of rust inhibitor to prevent internal corrosion.

Is the coolant mixture 50/50 water and ethylene glycol?

Is the coolant mixture providing protection to --35° F (--37°C)?

Is the coolant mixture being used for both summer and winter operation?

Is a reputable brand of rust inhibitor added when using water alone?

It is recommended to test the freezing protection of the coolant every six months or prior to freezing temperatures. Replenish with a fresh mixture every twelve months. A drain for the system is located in the bottom radiator tank. An alternate method would be to disconnect a bottom radiator hose.

Is the freezing protection of the coolant tested every six months or prior to freezing temperatures?
