• Leaking Radiator: Cracks or holes in the radiator cause the loss of coolant.
• Broken Water Pump It circulates cooling fluid and any issue can lead to overheating.
• The filtering of the Radiator Fins is clogged. Debris and dirt can stop airflow and reduce the efficiency of cooling.
• Infected Belts or Hoses belts and hoses could hinder the flow of coolant.
