Question:

Approximately how much fluid should be added to compensate for the extra cooling unit. I have a Toyota RAV4 2018 Le two wheel drive. Would like to purchase the 8000 model Class 2 cooler.

The amount of transmission fluid you'd need to add after installing a transmission cooler like the Derale # D13501 really depends but typically it's around 1/2 of a quart. I wouldn't totally adhere to that figure though as the amount that spills out during the install process will vary. Best option is install the cooler with extra fluid nearby and then add as needed once the process is complete.
