Did I put the wrong style power steering cooler on the car?

[darkostoj]

I had this cooler laying around.



Its a Rolls Royce with a Dodge Viper V10 in a 2nd gen camaro frame with a Saginaw AGR power steering box.

I plumbed it in the return line with 3/8 tubing. The high pressure line is 8AN

I tried 3 pumps and they are all super noisy and blow power steering fluid out of the vented cap.

I see a lot of the coolers use the tube and fin style and not the reservoir style. Is that what's causing the problem?

Do I need to change the pressure valve in the pump?

I'm stumped.

Thanks!
