And about 8,000 miles, I deleted the factory power steering cooler on my M6 car, Combination of other projects, laziness, and no evidence of leakage kept it on the back burner all this time.
Thankfully there was no contamination. And from now on, no worries!
The one on my '02 car never started leaking either. I bypassed it in, I think, 2012 but didn't bother to replace the hose, so it was just a pass-thru. It had around ~100k miles at that time. I was going to remove it entirely when I replaced the radiator (small cracks were starting on the tank) but I ended up selling the car before ever getting around to this.
Yep, this car has 94k now and no leakage. But figuring the likelihood that I'll keep this car for a good many years to come, and the mess that guys have gotten into when it does leak, it was worth the peace of mind.
My 2000 Formula didn't come with one. The rumor is that by 2001 all the LS! cars were getting them as power steering pumps were burning up and GM wasn't thrilled to replace them under warranty.

My '02 was just a base Z28 and it came with this standard. Not really sure how it would have helped to keep PS fluid temps down with stock fan settings though. Back about ~10 years ago I did some fluid temp testing after deleting the cooler on my '02. I posted all the results in the huge PS cooler delete sticky in the General Maintenance section. PS fluid temps ended up being cooler than coolant temps (with stock fan settings) after the cooler delete, even on a warm ambient day. You'd have to really push the PS system hard to get any actual "cooling" out of that cooler (or retune the fans to cut on much earlier). In stock configuration, it was more of a "warmer" under typical street conditions.
Yep, I always wondered about that. How does running the PS fluid through a hot coolant tube "cool" it? I can only presume the prevailing assumption is that the PS fluid would typically run hotter in most situations, like at 250* vs. a 210* coolant temp. Even in that case, it doesn't seem that a whole lotta cooling would be going on. And your testing indicates that this wasn't the case at all. As you say, it probably served more as a "warmer," which is what common sense would suggest.
