DRIVE January 29, 2026

A cooling arrangement for an electric transaxle includes a first coolant path configured to direct coolant to power electronics of the electric transaxle, a proportional valve downstream of the power electronics and configured to selectively proportion the coolant into a first portion directed to a second coolant path and a second portion directed to a third coolant path, and a heat exchanger configured to remove heat from the coolant in the second coolant path. The second and third coolant paths run in parallel to one another and direct the coolant to cool at least one of an electric motor and a transmission of the electric transaxle.
