Installation Notes

Cooling system service should be performed by a qualified automotive or fleet technician. Always allow the engine to cool completely before opening the radiator cap or any coolant lines to avoid burns from pressurized hot coolant. Dispose of used antifreeze according to local environmental regulations, as ethylene or propylene glycol-based fluids require proper disposal. Follow the vehicle manufacturer's dilution ratio recommendations when mixing with distilled water.
