To keep the big 'Burb cool, we went with an aluminum radiator from Custom Aluminum Radiator in Kingman, Arizona. We were able to use the stock mounts by simply spacing them upward a slight amount. Initially we were going to run an electrical fan on our 'Burb, but decided to use a mechanical fan for sheer simplicity. Since the serpentine belt system uses a reverse-rotation fan, we had to find a fan with the matching pitch. We found one at Performance Automotive Warehouse. While it might look like the fan is too far from the radiator, this is actually its stock position.
