Q
can too much coolant cause check engine light
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
Excess coolant can indirectly trigger the check engine light CEL. This occurs because when the coolant reservoir is overfilled. it increases pressure in the cooling system. potentially causing leaks or impacting radiator efficiency. In modern vehicles. sensors are installed to monitor cooling system performance. If any irregularities are detected. such as abnormal temperatures or pressures caused by excess coolant. the on-board diagnostics OBD will activate a CEL error code. To avoid both the CEL and potential damage to your vehicle. it is crucial to maintain the recommended coolant level. If the CEL illuminates and a coolant issue is suspected. be sure to check for leaks and correct levels before seeking professional assistance for accurate diagnosis and repair. Keeping up with routine maintenance of your cooling system will prevent unnecessary alarms and keep your vehicle running smoothly.
