Using this product helps ensure the final water content in your cooling system falls within the limits required for waterless coolant performance. It also contains corrosion inhibitors to protect metals during the cleaning process, though it is not a replacement for Evans Waterless Coolants themselves.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this prep fluid improve a cooling system before installing waterless coolant?\u003c\/h3\u003e\n\u003cp\u003eThe prep fluid actively dissolves and mobilizes pockets of old glycol-based coolant and trapped water left after a routine drain.
