I recently added a TruCool Max to my 1995 PSD. I removed the existing cooler that was mounted in front of the A/C condenser and extended those lines to the new cooler. I mounted the new cooler behind the stock front bumper. Pretty easy to do and it's working well. I don't have the bypass valve on mine, so I can't offer any insight there.
