WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2003 Pontiac Grand Prix, 2003 Pontiac Bonneville, 2003 Chevrolet Monte Carlo, 2003 Chevrolet Impala, and 2003 Buick Regal. However, it is still accessible from the selected car via links, so may be relevant.
The HOT COOLANT INDICATOR illuminates when the PCM determines that the coolant temperature is greater than 262°F (128°C). The HOT COOLANT INDICATOR control circuit is grounded by the PCM, causing the HOT COOLANT INDICATOR to illuminate. The IPC performs the displays test at the start of each ignition cycle. The HOT COOLANT INDICATOR will illuminate during this test.
