How to use
Drain and flush the existing loop according to your system manufacturer's instructions before filling. Do not mix ES Liquid GL50 with other coolants or additives. Fill the loop with ES Liquid GL50, purge air from the system until circulation is stable, then top up to the required level. Check for leaks and allow the system to run briefly to ensure proper flow and temperature stability.
Usage recommendations
Use ES Liquid GL50 only in single-product fills—mixing with other liquids voids warranty and can alter protective properties. Follow regular inspection and maintenance schedules for fittings, hoses, and radiators to ensure long-term performance.
