I came across this Moroso Heat-Sink Transmission Cooler/Filter p/n 41200


Moroso claims:
*Combination cooler/filter uses efficient "Heat Sink" configuration to dissipate the excessive heat build up in racing transmissions
*Made of aluminum with 500 sq. inches of radiation surface for high heat transfer
*Filter with magnet removes all wear particles over 4 microns in size
*Dimension: 3" in diameter, 12" in length, and weighs only one pound
*Very easy to install; not recommended for street use
*Comes complete with filter cartridge and all necessary installation instructions


I was wondering if this would be a good power steering cooler canidiate, plumbed into the stock return line. Runs $68.95 from Summit. Any clue why the "not recommended for street use" disclaimer?

SSeabrook,
I have seen a factory p/s cooler about the same size as the Perma-cool unit you have installed on a '00 Mercedes-Benz CL500. I've also seen a '92 Honda Prelude with a factory p/s cooler that looks like this one. Perma-cool's powersteering cool website is here.

What about running your choice of cooler, then plumb a filter into the return line. Navy Lifer sugguests in this thread either ACDelco: P/N PF883 or WIX: P/N 58964.

How would a normal spin-on oil filter work in this siutation? Maybe use a remote oil filter mount and a standard engine oil filter plumbed into the return line just before the line enters the reservoir. The plus side to this would be filtration of course, but also increased fluid capacity of around 1 quart. I don' think the line pressure is really an issue in this portion of the system. When replacing the filter, I thinking, pre-filling it with p/s fluid would help. Any remaining air bubbles would flow to the reservoir and escape through the cap.

Questions, comments, conerns on my ideas?
