Power Steering Cooler on 99? WTF? Do the 1999 Formula's come with power steering coolers?
WTF!!!
There literally is one on my friend's Formula and it was a PITA to get it off!
Do we really need it?
This is a SHOCKER to us as we have never seen one!

Are they needed? I say yes. Check out the power steering resevoir on any f-body without one and you'll see evidence of the fluid boiling over past the cap.
Is the inline factory one the best option, probably not. You're better off getting a plate style cooler from one of the big warehouses along with some fluid lines for less than $50.

Mine formed a leak between the coolant and power steering side. I just bypassed it. No overflow or boiling of my power steering fluid for over a year now. Works well enough without, but I would say that a plate cooler would be a smarter move. It's on my list of eventuals.
There could be some. Not that I've noticed while under the hood, and I'm under there more than I probably should be. Or maybe not enough. Either way I'll look closely next time I'm in there. Another thing that I should mention is this is by no means my daily driver. So someone who drove their car on a regular basis may have more of an issue.

If you ever autox or road race, you will get overflow. Or doing donuts.

They are very simple to remove & all you need to do is re-route the power steering hose thats connected to it & then buy a top radiator hose that comes in one long piece w/o the cooler. Its like a 10 minute job & the hose cost like $20 max.
Mine ruptured & was leakin power steering fluid into my coolant, so i got rid of the POS & never looked back. Haven't had a single issue & i dont feel they are needed unless you plan to autocross & really heat the pump up.

The PS pump will run at over 12psi when the rpm comes up. However our rack needs only about 3 psi to turn the front tires. So the fluid is bypassed in the rack and flows back to the pump. When auto crossing or doing the driver event weekends you stay at high rpm alot. All that fluid moving around creates a lot of heat. My Z28 did not have a PS cooler installed by the general. The cooler is mostly found on the SS models. I run royal purple fluid and yet ruined 2 PS pumps on the track in 1 summer. I bought a cooler with hoses off a guy and installed it. No more PS pump issues even on the track. There is another option if you do not want to run a cooler. You can install a Turn One PS pump that is specially made to lower the pressure and thereby greatly reducing the amount of fluid bypassed and the resulting heat. Hope this info helps

They started in 01. They weren't trying ti use up all the inventory, they were trying to stop warranty claims on burnt up pumps.
If you wanted it and went to a dealership that would actually look into ordering what you wanted; you could get it.

Sorry, I had a crappy dealership that wouldn't do that. And when I bought my 2nd 99 in January 2000 they were hard to come by (any LS1). I had a black TA before this pewter one.
