Back Flush Procedure
WARNING: This page is about a different car, the 2019 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
Connect the DT-45096-50 cooler flush adapter (1) to the vehicle transmission oil cooler supply and return lines at the transmission.
Connect the black supply hose (1) to the return line, top connector of the transmission, and the clear waste hose (2) to the feed line, bottom connector of the transmission, to the vehicle cooler lines. This is the reverse flow - backflush direction.
Turn the main function switch to the FLUSH position. Allow the machine to operate for 30 seconds.
Turn the main function switch to the IDLE position and allow the supply vessel pressure to dissipate.
