What should I do if the cooling system is filled with the wrong Coolant/Heat Transfer Fluid?

Drain the Coolant/Heat Transfer Fluid completely and flush the system thoroughly with water (see our recommend a mixture for flushing the system) and then fill with the correct Coolant/Heat Transfer Fluid in the appropriate concentration.
