ABSTRACT:
An engine coolant temperature estimation system comprises a coolant temperature estimation module and a coolant monitoring module. The coolant estimation module estimates an engine coolant temperature based on at least one of a mass air flow, a vehicle speed, and an ambient temperature. The coolant monitoring module selectively operates an engine based on the estimated engine coolant temperature.
