The custom Killer Chiller Tank is a direct fit where the OEM heat exchanger was. Notice the stock Bosch pump (upgraded to the -010 model) plumbs directly into the tank using the factory hose. The transmission cooler mounts to the bottom of the tank, and the tank itself mounts using the factory bumper bolts.
The factory return line gets a union fitting and a length of hose going over to the Killer Chiller on the driver’s side.
