Usage Note — For Maximum Performance

For the best cooling performance from PG55 RC, we recommend flushing the system twice before your final fill:

• Ideally, rinse two times with PG55 RC (recommended for maximum purity), or
• Rinse two times with flash water (clean distilled or de-ionized water) to remove old residues.

Ensure that all remaining coolant—especially ethylene-glycol-based coolant—is completely removed before filling with PG55 RC.
If your system already contains PG55 RC from a previous fill, flushing is not necessary for continuous use.
