I tried the product and my radiator has a white crystalline deposit or jell, what is this?
These are tell-tale signs of a radiator that is in need of service. When fluids are not changed often enough under severe operating conditions or in areas with hard water, scale deposits may form in the passages. Sometimes old fluids will jell or crystallize and can be seen in the system. To remove these deposits flush cooling system using a flushing agent and/or a flushing machine.
