Wynn’s® Cooling System Cleaner provides safe, effective cleaning for automotive cooling systems during fluid exchange. When added to vehicle’s used coolant prior to fluid exchange, it washes away rust and deposits as the used fluid drains. Prepare the Cooling System for fresh, clean anti-freeze for improved flow and heat transfer.

Add to used coolant and circulate at engine operating temperature for a minimum of 10 minutes. Use the Wynn’s® PowerFlush (P/N 07600) to complete the system service.
