I finally found out where my power-steering fluid was leaking from.
After taking off the front plastic facia (which was easier to do than I thought), the leak was easy to see.
The so-called power-steering fluid cooler is just a 4-ft long piece of aluminum tubing bent into a long U shape and mounted sort-of under and in front of the radiator. Rubber hoses connect to this pipe on the driver's side using simple hose-clamps.
The pipe is welded to a pair of brackets that are bolted to the underside of the radiator bulkhead. A small radiator (tranny cooler?) is mounted to the front side of the radiator, directly behind this cooler-pipe. The inlet and outlet for this small rad are located on the bottom side. The PS cooler pipe was in direct contact with one of the inlet/outlet nuts of this small rad.
One of the brackets must have been bent slightly during a minor front-end impact with either a snow bank or parking curb, causing the pipe to remain in constant contact with the nut. This caused a hole to be worn into the pipe, causing the leak.
Here's what this cooler-pipe looks like:
I could probably make one, it looks so simple in design.
Since it's the fall and the temps are going to get cold, I could probably just bypass this thing by connecting the hoses together.
But I wonder if the power steering fluid gets so hot that you really need this stupid piece of pipe?
