I mounted the transaxle cooler to the custom tail sub frame (more about that later). I used the same Nissan vibration isolators that I used on the intercoolers and mounted them with four tabs that I designed and laser cut from 0.104” mild steel. The upper two were bent and tacked to the tail sub frame and the bottom two were tacked to a bracket that I fabricated from 1/2” mild steel tube — I’m glad that I didn’t use 4130 because it was difficult to shape with a manual bender!
The M6 screws were swimming in the bushings so I replaced them with M6 shoulder screws with an 8 mm shoulder diameter. The shoulders were too tight so I opened the bushings with a drill bit.
The next step is to mount the thermostat and fabricate the lines. When I get around to fabricating the new tail, I’ll mold a fiberglass duct to the underside of the tail which will transition to an aluminum duct around the cooler.
