My Turbo Subie powered 84 GL with AT governor mods was generating so much extra heat that it destroyed the seal between the final drive and trans section before I acquired the van. It now sports an external cooler with a fan. Others have argued that the fan is not needed. Fellows like TerryK just sell scoops supposedly adequate to the task. I am happy to have the extra cooling especially whilst idling in traffic.
My cooler sits aft of the area below the sliding door.
