Aluminum Radiator Maintenance
Proper maintenance of an aluminum radiator is essential for the longevity and efficiency of your vehicle's cooling system. Start by performing a complete flush of the entire cooling system, including all hoses and the engine block, to ensure it is free from old fluid or contaminants. Always refer to your user manual for the correct type of coolant and maintain a 50/50 mix of coolant and water. Failing to do this can lead to
electrolysis, where electricity flows through the system, causing severe corrosion and pitting on the aluminum surfaces. To avoid this, regular maintenance every 30,000 miles is recommended, including flushing and inspecting the system. Additionally,
NEVER use the radiator as a ground for electrical components, as this can accelerate electrolysis and lead to further damage.
