Do cars ever use electric water pumps?

처리 내용

BMW abandoned their mechanical water pump in the 3 series when they moved to the E90 generation in 2006. The electric pump is the only pump. A quick search reveals that all other typical cooling system components (i.e. thermostat) still exist, so even when the engine is warming up the coolant circulates. This is probably to prevent hot spots which could happen if the pump just stopped. There is a flow sensor for feedback so if the pump starts to fail the ECU can set a trouble code. E90 owners have reported low flow code as much as a month before total pump failure, but I'm sure reliability and failure rates vary by make/model just like anything else. It seems there are two primary benefits to electric pumps: They don't need a drive belt, so they may be located virtually anywhere. They can run with the engine off. Running with the engine off seems trivial for non-turbo and non-hybrid cars until you consider that most European cars turn off their engines if they come to a complete stop f
