Engine Coolant Temperature Gauge The engine coolant temperature gauge This gauge indicates the engine coolant temperature not the coolant level. If the coolant is not at its proper level or mixture, the gauge indication will not be accurate. It is identified by a thermometer symbol, an "H" (hot), and a "C" (cold). The "NORM" indicates the normal operating range. The bars will move into the normal operating range as the engine coolant warms up. It is acceptable under certain driving conditions such as, heavy stop and go traffic, or driving up hills in hot weather, for the gauge to indicate at the top of the NORM band. If, under any circumstance, the pointer moves above the NORM band, the temperature symbol flashes and a tone will sound to alert the driver that the engine coolant is overheating and continued operation may cause engine damage. If your engine overheats: 1. 2. Pull off the road as soon as it is safely possible. Turn off the engine. If you do not stop the engine as soon as safely possible, severe engine damage could result. 23
