The TECH brand or any brand is okay as long as it's not the stuff meant for a Honda.

With the car parked on a slope, is the leak under the steering box or the pump? I expect that it is under the steering box and if so, check the Pitman shaft seal.

ktlimq,

Don't pull the clamp and the hose off the fitting. Use a wrench to remove the fitting with the clamped hose still connected. This is easier and more importantly gives you an L fitting that directs the flushing fluid downward into the drain pan.

Good luck,
