1) I assume bleeding a evo is like bleeding other cars.
2) Go to GADSM and ask the question there also.
3) Check the power steering level and make sure it is full.
4) If full, Turn the car on.
5) Turn the steering wheel all the way to the left and right. Keep doing it... You should hear a whine or buzzing noise.
6) check the fluid level again. Refill if need be.
