Will a Broken Radiator Cap Cause Overheating?
1 Answers
A broken radiator cap will not cause the engine to overheat, but it can lead to coolant loss. The reasons for engine overheating are as follows: 1. System blockage or internal obstruction of the radiator. 2. Mechanical blockages, such as a malfunctioning or damaged thermostat, or a faulty water pump. 3. Air lock, where high pressure from the engine cylinders enters the cooling system. 4. Poor heat dissipation, such as low-speed cooling fans, damaged fan shrouds, or a dirty radiator surface. 5. Cars with electric fans may experience delayed fan activation. Note: Regardless of the cause, it is essential to stop the vehicle promptly and avoid driving forcefully. Overheating prevents proper engine cooling, which can lead to engine damage or failure. Once the temperature drops, drive slowly. If the temperature rises rapidly again, stop immediately and do not restart the vehicle. Seek professional repair assistance or have the car towed to a 4S shop for inspection.
