Method and systems for determining when to cancel coolant stop. An initial coolant temperature value is measured. The initial coolant temperature value is used to create Multiple Control Valve (MCV) opening thresholds. A first threshold is generated for MCV opening threshold for engine speed. A second threshold is generated for MCV opening for intake air mass flow. A comparison is made between the first threshold and the currently measured engine speed and/or a comparison is made between the second threshold and the currently measured intake air mass flow. The comparison(s) are then used to determine when to cancel coolant stop and open the MCV.
