Thanks for the replies. My mind is made up, my cooler will be on today. One question though. On the hydroboost system, there are two low pressure lines. One is the return from the steering box which I know I could plumb into no problem. The other low pressure line is from the brake booster. There are two high pressure lines going to this unit and I'm ASSuming the small low pressure is for "left over" fluid and sees little volume. The only reason I ask is it would look much cleaner if I ran the cooler from the brake booster line.
For those not familiar with the 84 system, it's like the 87 except the pump feeds the brakes first, then to the steering.
My car seems like it's becoming one big cooler lol. I have a huge FM intercooler, two tranny coolers, an external oil cooler, and now a powersteering pump cooler. I'm starting to run out of room.
