Abstract
Examples of techniques for controlling coolant flow in a vehicle cooling system for an internal combustion engine using a secondary coolant pump are provided. In one example implementation, a computer-implemented method includes receiving, by a processing device, engine operation data about the internal combustion engine. The method further includes detecting, by the processing device, a shutdown of the internal combustion engine. The method further includes calculating, by the processing device, an engine flow based at least in part on the block flow request and the head flow request. The method further includes, subsequent to detecting the shutdown of the internal combustion engine determining, by the processing device, an after-run condition based at least in part on the engine operation data. The method further includes activating, by the processing device, a secondary coolant pump based at least in part on determining the after-run condition.
