1. Replace the radiator hose every three years or 36,000 miles. Since hoses are rubberized and will dry out and break over time, their mileage should not exceed 50,000 miles.
2. Regularly check the coolant level. If the liquid level drops significantly between the two inspections, there may be a leak in the car's water tank. It is important to pay close attention, because slow leaks can be difficult to detect.
3. Flush the coolant every 25,000 miles to remove any contaminants from the radiator and its hoses. The service also regulates the cooling system to help prevent rusting of the components and allow them to operate at peak performance throughout their life cycle.
