Save yourself some major engine repair bills by ensuring the health of your Eagle water pump - keep enough coolant and water in your system, and check your hoses regularly for leaks. You can prevent, or at least slow down, the effects of corrosion on your Eagle water pump, which is a major cause of failure in that component. To prevent failure in your Eagle water pump, check the belts and hoses at regular intervals. Change your coolant every two to three years, and then every five years, get your coolant system flushed. That will help clean out the corrosive filth that has collected in your cooling system over the years. Replacement is required when the coolant losses its anticorrosive powers; most standard antifreeze mixtures will do that in about 2 years or 24,000 to 30,000 miles. Flushing helps to cut down on the air, gasses, impurities, deposits or rust in the coolant fluid. Use distilled water, and cut back on the levels of calcium, lime and other minerals that will clog your radiator. In an emergency, use tapwater but be aware that softened water contains salts that will damage the cooling system of your Eagle vehicle. Look for coolant leaks under your car, since that is the first sign of trouble. If the Eagle water pump has reached the point of failure, it is time to replace it with a new set that you can purchase here and install yourself.
