Electronically controlled electric BLDC coolant pump

"Electronically Controlled Coolant Pump
Particular care must be taken when performing servicing work to ensure that the pump does not run dry. When the pump is removed, it should be stored filled with coolant. The bearing points of the pump could seize if the pump were not filled with coolant.
This could jeopardize subsequent start-up of the pump thus rendering the entire heat management system inoperative (the pump not starting up could cause serious engine damage). If the pump should ever run dry, the pump wheel should be turned by hand before finally connecting the coolant hoses. The system should then be immediately filled with coolant.
Particular care must be taken during assembly to ensure that the connector is clean and dry and the connections are undamaged." Page 70 - 71

It should be obvious that the Graphitar plain journal bearings of the ECP will corrode in a used pump or a new pump as well. A new pump should be received wet and stored up-right only.

Eschew eristical argumentation. I am responsible for what I write, not for your understanding of it.
