The low coolant light on a 1999 Buick Regal with a 3.8L engine may remain illuminated until the engine reaches a certain temperature due to a faulty coolant level sensor or a problem with the cooling system. If the coolant level is adequate but the sensor is malfunctioning, it may incorrectly signal low coolant. Additionally, if the engine is cold, the coolant may not circulate properly, causing the sensor to read low until the engine warms up and the coolant expands. It's advisable to check the coolant level and sensor functionality to diagnose the issue accurately.
