04|Recommendations
Keep engine temperatures under control.
Proper coolant maintenance helps maintain stable engine temperatures, protect cooling-system components, and support reliable vehicle performance over time.
01
Use as Directed
Radiator Coolant is ready to use. Do not dilute with water unless specifically recommended by the vehicle or equipment manufacturer.
02
Check Coolant Levels Regularly
Inspect the coolant level at recommended intervals and top up as required to maintain proper cooling-system performance.
03
Flush Before Replacement
Flush the cooling system before replacing old coolant to remove contaminants and help achieve maximum cooling and protection.
04
Follow the Service Schedule
Replace coolant according to the vehicle manufacturer's recommended maintenance schedule or applicable service interval.
05
Prevent Contamination
Keep the coolant container sealed and prevent dirt, water, oil, or other contaminants from entering the cooling system.
06
Avoid Incompatible Mixing
Do not mix different coolant types or formulations unless compatibility has been confirmed by the manufacturer.
