I'm cutting out the power steering cooling lines from in front of my air con heat exchanger so I have more room for my intercooler. I'm going to mount 2 oil coolers in the fender, one for the auto trans and one for the power steering, I have a GSX-R 750 thermo fan to suck through the cores and I have the speed switch and relay to turn this fan on below a certain speed.

My question is how big should the power steering cooler be? I already have 1 of these for the trans {DESCRIPTION}

my stock power steering cooler is about 10" long about 2" wide, it's not very big at all.
