Why does your car overheat going uphill?

Your car may overheat going uphill due to increased engine load, which causes it to work harder and generate more heat. This can overwhelm the cooling system, especially if there are issues like low coolant levels, a failing thermostat, or a malfunctioning radiator. Additionally, reduced airflow to the radiator when climbing can hinder heat dissipation. If the overheating persists, it’s important to have your vehicle checked to prevent engine damage.
