An electric drive unit for powering a load, e.g., road wheels of a motor vehicle, includes a housing having a floor section separating the housing into upper and lower chambers. The floor section defines an elongated drain opening, drain holes, and an oil supply port in fluid communication with an oil pump. A rotary electric machine is enclosed within the lower chamber, and has electrical leads positioned directly below the drain opening. A cover assembly is fastened to the housing within the upper chamber, and has a coolant channel assembly integrally connected to a cover plate. The coolant channel assembly includes electrical terminals that project through the drain opening and are fastened at a first distal end of the electrical terminals to the electrical leads. The cover assembly defines a primary coolant channel in fluid communication with the oil supply port, and directs oil to the electrical terminals.
