Wynns Radiator Flush

✓ Add to the cooling system via the expansion tank if part of the system circuit (2 hoses: out and return), or directly into the radiator if a single hose overflow tank is fitted. ✓ For higher performance, first replace the old coolant by water, then add Wynn’s Radiator Flush. ✓ Warm up the engine with the heater control in HOT position. ✓ Let the engine run at idle for 10 minutes. Heater still in “hot” position. ✓ Stop the engine and allow to cool, open drain valve and empty the system. ✓ With system still open, flush with water until clear, close system and refill with coolant. ✓ One bottle of 325 ml treats systems up to 7 litres.
