Power Steering "Heater" Delete
My temps BEFORE were about the same as "M4N14C"....210-215 driving in South Florida temps. That's friggin hot. And its just about the same as the coolant temps are.
AFTER the aftermarket cooler was put on my PS fluid temps would never go above 120*F......even in stop and go traffic on a 90*F day. I used a laser temp gauge.
BUT.....I think a big part of my cooler PS fluid temps is because of the cut-out I made in front of my cooler in the air dam.....so the cooler gets constant ram air cooling...not just static air....or some swirling air from forward movement. And NO....the cut-out has absolutely zero affect on coolant cooling.....

Stock lines weren't long enough to reach my cooler so I extended them with the ones included in the kit.

160 is way better than stock.....so that's good enough.
A couple friends I know just removed the factory cooler.......did not install an aftermarket cooler.....their temps dropped to around 170-180.....
Never do they reach 200-220.......like it does with the factory cooler on there. So it proves even without a cooler at all on there......it runs cooler than with the factory...."PS FLUID HEATER".......

This has been my observation as well. I didn't see anything higher than 18x on days up to 90°F (which is about as hot as it usually gets here in the summer), with most of the readings in the 160-180 range in average temps.
I think the testing that RPM WS6 did a while back showed the potential for the stock system to raise fluid temperatures, but I don't think we really understand "why" GM put the system there in the first place. The stock system is inexpensive - so we can infer that cost is the reason why the design was chosen, but there must be some condition out there or set of circumstances that would cause the stock P/S system to rise in temperature way above 210*. I'm not sure we have found that, yet.

Yes, I can vouch for that stuff, as it is what all of the road racers use to prevent boilover problems, even with a very large power, air to fluid, steering cooler.
