Instruments and Controls Notice: Lack of proper engine oil maintenance can damage the engine. Driving with the engine oil low can also damage the engine. The repairs would not be covered by the vehicle warranty. Check the oil level as soon as possible. Add oil if required, but if the oil level is within the operating range and the oil pressure is still low, have the vehicle serviced. Always follow the maintenance schedule for changing engine oil. If the vehicle has a diesel engine, see the Duramax diesel supplement for more information. If the vehicle is a hybrid, see the hybrid supplement for more information. 5-15 Engine Coolant Temperature Gauge English Metric This gauge shows the engine coolant temperature. It also provides an indicator of how hard the vehicle is working. During a majority of the operation, the gauge reads 100°C (210°F) or less. If pulling a load or going up hills, it is normal for the temperature to fluctuate and go over the 113°C (235°F) mark. If the gauge reaches the 125°C (260°F) mark, it indicates that the cooling system is working beyond its capacity.
