Malfunction Threshold
The engine running time before the engine coolant temperature reaches 0 °F (-18 °C), based on the initial engine coolant temperatures, is as follows:
MALFUNCTION THRESHOLD
| Initial engine coolant temperature | Engine running time |
|---|---|
| -54°F (-48°C) | 5 minutes or more |
| -35°F (-37°C) | 5 minutes or more |
| -0°F (-18°C) | 1 minute or more |
