The engine running time before the engine coolant temperature reaches 98°F (36°C), based on the initial engine coolant temperatures, is as follows.
INITIAL ENGINE COOLANT TEMPERATURES
| Initial engine coolant temperature | -54 °F (-48 °C) | -35 °F (-37 °C) | 0 °F (-18 °C) |
| Engine running time | 300 seconds or more | 60 seconds or more | |
