Claim 11:
12. A method of cooling electrical components of a vehicle, the method comprising:
directing coolant from a coolant loop into a power module containing one or more inverters, wherein (1) the power module is coupled to a substantially metal casting that is mounted to a frame of the vehicle, and (2) none of the coolant from the coolant loop directly contacts any surface of the metal casting, wherein directing coolant further includes:
a) directing coolant through a capacitor housing including a first coolant channel, the first coolant channel being on a first surface of the capacitor housing;
b) directing coolant out of the capacitor housing and then into the power module through two or more parallel coolant channels extending through the power module, wherein the power module is located externally of the capacitor housing, and
c) directing coolant out of the power module and back into a second coolant channel on the first surface of the capacitor housing,
wherein the two or more parallel coolant channels are in parallel with the first coolant channel and the second coolant channel.
