Cleaning the Radiator Core
Cooling efficiency is compromised when there is dirt or dust plugging air passages in
the radiator core. It also could cause corrosion of the radiator core. Periodically wash
the radiator core with water.
ADVICE
• When cleaning the radiator core, do not crush or damage the fins.
