Power Steering Fluid Cooler
By Tom Moxey
This past year I had the opportunity to really push the capabilities
of my 91 SE-R at Nelson Ledges Road Course in Northeast Ohio. It's a bare-bones 2.0 mile,
13 turn flat course that is very fast. What I found was that Porsche Boxsters don't have
too much on our SE-R's. I was all over these guys like a cheap suit most of the time. They
have better straight-line acceleration, but I always reel 'em in at every turn
which brings me to my point. After lapping all day, the fluid overheats and the assist
starts to go away. So, I thought a small cooler would fix the problem and provide a bit of
reserve fluid as well.
Grab a JEG's catalog and check
out part number 771-1007. It's a small cooler with all the hose, fittings and clamps
- Empty the reservoir of as much fluid as possible. Stuff an old, big
towel under the reservoir to catch the impending mess.
- Cut the supplied hose exactly in half and attach the pieces to the
cooler with the clamps. The cooler will mount at the upper right most part of the radiator
with the ties supplied. Mount with the hoses exiting the cooler towards the right fender
and route them to the reservoir. Take care to avoid pulleys and belts in this area. Use
tie-wraps to secure the hoses in a safe manner.
- Now comes the messy part: loosen the clamps on the hose that attaches
the stock cooler to the bottom of the reservoir.
- In one quick move, pull the hose from the bottom of the reservoir and
attach one of the hoses from the cooler. Hope you remembered to slip a clamp on the new
clamp it on.
- Now basically do the same for the end attached to the existing
- Add fluid as needed to bring the reservoir to the max full level and
start the car.
- Drive it around a bit and recheck the fluid level. You're done.
For you inline racers, don't waste your time on this mod. For you
road racer nuts
it proved to be a beneficial $32 and 30 minute mod.
