The OEM power steering “cooler” on the R32 is just an extended hard line that loops in front of the radiator. I know that the power steering fluid always over heats in the summer so I needed to add a real cooler. All I did was get a transmission cooler from Autozone, remove the hard line and install it. Pretty easy.
And you can also tell from the pictures that I got my new radiator in. Koyo, nothing special. It works.
