Coolant levels should be checked regularly at the reservoir. If the coolant is low, add a 50/50 mixture of distilled water and your vehicle's approved coolant to "top off". If you find a repeated need to add coolant your system should be checked for leaks.
A visual inspection of belts, hoses and the radiator can help identify problems before they become critical. Radiator leaks, bulging or cracked hoses and frayed or cracked belts all indicate a need for maintenance.
Get your vehicle serviced immediately if you experience engine overheating, coolant leaks, steam or hissing sounds from under the hood, or smell antifreeze.
