In the last few days, I’ve encountered a puzzling issue with my vehicle. Whenever I’m at a standstill, my engine begins to overheat, but the temperature seems to stabilize once I pick up speed. I’m uncertain if this is related to a faulty thermostat or another underlying problem. Could you help me understand why my car overheats only when idling?
Hello Joey,
It’s concerning to hear about your car’s overheating issues during idle times. Typically, this problem is indicative of a malfunctioning radiator fan. The radiator fan plays a crucial role in cooling the coolant fluid after it has absorbed heat from the engine. This process is vital for maintaining your engine’s optimal temperature.
When your car is moving, the natural airflow helps in cooling down the coolant. However, at idle, your vehicle relies solely on the radiator fan to perform this task. If the fan is broken or malfunctioning, it won’t cool the coolant effectively, leading to an overheated engine when you’re not moving.
While a faulty thermostat could also be a culprit, the symptoms you describe lean more towards a radiator fan issue. We recommend consulting a professional mechanic who can diagnose and repair the radiator fan. This should resolve the overheating problem and ensure your car runs smoothly, whether you’re at a stop or cruising down the road.
Stay safe and take action promptly to avoid further complications. Best regards,
