Power Steering Cooler
Ok, my '03 has a PS cooler, but it's pretty tiny. Does anyone know if this thing really works? Anyone know what max temps for the fluid are permitted without breaking the fluid down? How about a PS temp gauge? 
I plan on putting a Tru-Cool on anyway, so perhaps delete the stock PS cooler and use the existing OEM tranny cooler?
Practicality?
Does the PS fluid really get too hot using no cooler or the OEM?

Someone recently posted that he inadvertantly replaced the stock P/S cooler with a larger one (thought it was the tranny cooler), and the resulting pressure drop messed up his brakes. The hydro-boost system on our vehicles uses the P/S pump to supply pressure for the braking system too.

Don't think I would lose the power steering cooler either. Just add another transmission cooler. The factory transmission cooler isn't that large to begin with. A second, larger one won't hurt a thing (except heater warmup time in the winter) when pulling that big fiver up a long grade.
JMHO, Joe
p.s. I was shocked to find a power steering cooler under there.

Even if there is a chance of messin' up the brakes, I'll leave it alone. Brakes are a very bad thing if they don't work.
Oh well, just a thought, I was thinking Johnny needed more gauges.
Johnny, don'tcha need to monitor the charge rate for the batts in yer 5ver?
We still need oil temp & pressure, volts, outside air temp, humidity, etc...
Hahahahahaha

Got one of those digital indoor/outdoor thermometers for 9 bucks. Just can't figure out where to put it. It's 1"X4".
Johnny, you forgot wind speed. We understand though, you have gauge envy.
